The invention relates to an improved water-based polymer coating composition comprising a polymer resin, water and surfactant. As an improvement over prior water-based polymer coating compositions an anionic and/or nonionic surfactant is present in an amount effective to plasticize the coating formed from the composition. A water-based polymer coating composition of the invention is also substantially free from cosolvents. The invention also relates to a method of coating a substrate and a substrate which has been coated with a coating formulation of the invention.

Use of surfactants as plasticizers to reduce volatile organic compounds in water-based polymer coating compositions

This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured. The latex is useful in variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like.

Adhesive compositions containing stable amino-containing polymer latex blends

Surfactant-containing acetoacetoxy-functional polymers (SAAP's) are described. The acetoacetoxy-functional polymer may be a surfactant-containing enamine-functional polymer and more preferably a surfactant-containing, polymeric (polyamino)enamine (PPAE). The PPAE is the reaction product of a surfactant-containing acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The polymers may be prepared as waterborne polymer compositions, such as latexes. The waterborne polymer compositions can be prepared with high solids content while maintaining low viscosity. Waterborne polymer compositions containing the polymers of the inventions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, and adhesives. When used in coating formulations, the polymers of the invention provide adhesion and crosslinking in the final film or coating. The film or coating may be cured at ambient temperatures or may be thermally cured.

This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne pendant-functional polymer particles; and water. The waterborne pendant-functional polymer comprises at least one pendant amine reactive functional moiety selected from the group consisting of carbonate, epoxide, isocyanate, isopropenyl, carboxylic acid, and allyl groups. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne pendant-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured. The latex is useful in variety of coating compositions such as, for example, paints, inks, sealants, and adhesives.

Surfactant-containing acetoacetoxy-functional and enamine-functional

This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispsered, waterborne acetoacetoxy-functional polymer particles; and water. In a preferred embodiment, a latex of the invention comprises dipsered, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invetion provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured. The latex is useful in variety of coating compositons such as, for example, paints, inks, sealants, and adhesives.

Stable amino-containing polymer latex blends

A water-based ink composition is described. The ink composition contains a pigment and a polymer latex. The polymer latex may be a polymeric (polyamino) enamine latex or a mixture of a polymeric (polyamino) enamine latex and an acetoacetoxy-functional polymer latex. The inks are particularly useful as laminating and surface-printing inks. Methods of printing are also described.

Use of stable amino-functional latexes in water-based inks

The present invention provides waterborne crosslinkable polymer compositions encompassing (A) functional latex polymers containing at least one pendant ethylenically unsaturated functional group, (B) a silicon hydride compound containing at least two reactive hydrogen atoms, and (C) a catalyst suitable to attain a crosslinked film.

Waterborne silicon hydride crosslinkable latex compositions and methods

This invention provides polymers useful in coating compositions. The polymers are prepared via a free radical polymerization using ethylenically unsaturated monomers. The polymers of this invention possess pendant allylic groups which are capable of effecting free-radical flux when the compositions are applied to a substrate and exposed to oxygen. Coatings formed from preferred compositions possess superior solvent, print, and block resistance.

Waterborne polymers having pendant allyl groups

Provided are allyl-functional polymers having pendant enamine moieties and preferably also possessing pendant methacrylate groups. The presence of such groups in the polymer allows for a free-radical crosslinking reaction to take place during film formation and provides coatings having superior solvent resistance. Amino-containing waterborne particles can be prepared by reacting propylene imine with carboxylic acid-containing latexes. The amino-functionalized latexes are subsequently reacted at room temperature with for example acetoacetoxyethyl methacrylate. During ambient and thermal cure studies, clear films exhibited significant increases in solvent resistance, gel fraction, and crosslink density.

Waterborne polymers with pendant crosslinkable groups

This invention relates to reactive polymers, e.g., aqueous emulsion polymers, having pendant flexible or dangling side chains prepared from ethylenically unsaturated carbodiimides, e.g., carbodiimide (meth)acrylates. The reactive polymers contain ethylenic unsaturation near the surface or in the surface area of the particles that form the polymers, the ethylenic unsaturation being connected to the polymer through the pendant flexible or dangling side chains. This invention also relates to the process for preparing the reactive polymers, to crosslinkable formulations based on the reactive polymers, and to thermoplastic and crosslinked films prepared from the reactive polymers. The reactive polymers are useful as decorative and functional coatings, inks, adhesives, textile coatings and sealants.
