An aqueous coating composition useful as electro-deposition coatings includes (A') an aqueous dispersion of a resin (A) having functional groups which are reactive toward isocyanate, and (B') an aqueous, solvent-free dispersion of a solubilized masked polyisocyanate (B). The coating is cured by baking at a temperature which regenerates the isocyanate groups.

Aqueous coating compositions comprising curing agents which can be

Aqueous synthetic resin dispersions comprising (A) an ionic resin, based on aralkylated epoxy resins, (B) a blocked polyisocyanate and (C) a polymer of at least one olefinically unsaturated monomer which is capable of undergoing free-radical polymerization are useful, for example, as binders in processes of coating by electrodeposition.

Aqueous dispersion of ionic aralkylated epoxy resin and blocked

Urethane-modified novolaks which are prepared by simultaneous reaction of a monohydric or polyhydric phenol (A) with an oxo compound (aldehyde or ketone) (B) and a urethane (C) in the presence of an acidic catalyst (D) at an elevated temperature of 60.degree. to 200.degree.

Polyurethane dispersions prepared by polymerization, initiated by free radicals, of polyurethane macromonomers containing carboxyl, phosphonic acid or sulfonic acid groups and lateral vinyl groups and optionally terminal vinyl, hydroxyl, urethane, thiourethane and/or urea groups. These polyurethane dispersions are suitable for the production of coatings on substrates, as adhesives or as binders in printing inks.

Polyurethane dispersions

Polyesters obtained by reacting from 5 to 50 parts of at least one linear or branched, aliphatic or cycloaliphatic, at least dihydric alcohol, from 2 to 40 parts of at least one at least dibasic, aromatic carboxylic acid, from 0 to 40 parts of at least one 2-alkenyldicarboxylic anhydride, from 10 to 30 parts of at least one at least dibasic, linear or branched, aliphatic carboxylic acid, from 0 to 15 parts of an aliphatic, linear or branched hydroxy acid, from 0 to 15 parts of an aliphatic, linear or branched polyamine having at least one primary and at least one secondary or tertiary amino group, from 0 to 15 parts of a glycidyl ester of a branched, aliphatic monocarboxylic acid or of a glycidyl ether of a branched, aliphatic alcohol, and from 0 to 15 parts of polyhydroxyamine are useful, for example, as additives in coating compositions.

Polyesters and their use as additives in coating compositions

Binders for powder coatings comprising A) a solid unsaturated polyester and B) a polyurethane comprising (meth)acryloyl groups. These polyester-containing mixtures are distinguished by an improved blocking stability compared with polyurethane alone.

Binders for powder coatings

An aqueous coating composition containing at least one water-dispersible polyurethane resin containing air-drying groups and optionally further binder resins and conventional paint additives, which polyurethane resin contains structural units derived from

Air-drying polyurethane resins, their preparation and use

Polymer mixtures comprising at least one amino group-containing polymer A) and at least one polymer B) of ethylenically unsaturated monomers, which mixtures are obtained by reacting an epoxide with an amine in the presence of the ethylenically unsaturated monomers, and then arrying out free-radical polymerization. These polymer mixtures are employed for the preparation of binder vehicles for water-based printing inks and print varnishes.

Polymer mixtures

Aqueous synthetic resin dispersions comprising A) an ionic resin, preferably a cationic resin, B) a blocked polyisocyanate and C) a polymer of at least one ethylenically unsaturated monomer which can be polymerized by free-radical polymerization. These synthetic resin dispersions are used as binders in electrodeposition coating baths.

Emulsifier-free synthetic resins and mixtures of synthetic resins with water are used as binders for water-borne printing inks and printing varnishes. The resins contain: (a) a polymer resin A containing acid groups which may have been neutralized or partially neutralized and can be prepared by in-situ polymerization of ethylenically unsaturated compounds containing acid groups with further ethylenically unsaturated compounds and condensation with monohydroxy compounds and, if desired, neutralization or partial neutralization, and (b) if desired, a water-insoluble polymer resin B in the form of latex particles which can be prepared by emulsion polymerization of ethylenically unsaturated compounds in the presence of the polymer resin A.
