An aqueous inkjet ink composition suitable for printing on a hydrophobic surface such as a vinyl surface including an aqueous emulsion polymer having a glass transition temperature (Tg) of from &#x2212;40&#xb0; C. to 150&#xb0; C.; a pigment; and a water-soluble surface agent is provided. Also provided is a method for providing an image on a hydrophobic surface and the image so provided.

Aqueous inkjet ink composition

An emulsion-polymerized addition copolymer formed from a monomer mixture comprising ethylenically unsaturated monomers including from more than 4 to 15 wt % based on the weight of said mixture of at least one ethylenically unsaturated carboxylic acid functional monomer, and from 0.05 to 5 wt % based on the weight of said mixture of at least one polymerizable surfactant monomer, comprising hydrophobic and hydrophilic functional groups, wherein said hydrophilic functional group comprises a polymerizable group within it, is useful as a binder in an ink jet ink having improved print quality.

Inkjet ink composition

An emulsion-polymerized addition copolymer formed from a monomer mixture comprising ethylenically unsaturated monomers including from more than 4 to 15 wt % based on the weight of said mixture of at least one ethylenically unsaturated carboxylic acid functional monomer, and from 0.05 to 5 wt % based on the weight of said mixture of at least one polymerizable surfactant monomer comprising hydrophobic and hydrophilic functional groups, wherein said hydrophobic functional group comprises a polymerizable group within it, is useful as a binder in an ink jet ink having improved print quality.

Polymeric binders for ink jet inks

An emulsion-polymerized addition copolymer formed from a monomer mixture comprising ethylenically unsaturated monomers, including from more than 4 to 15 wt % based on the weight of said mixture of at least one ethylenically unsaturated carboxylic acid functional monomer, and from 0.05 to 5 wt % based on the weight of said mixture of at least one polymerizable surfactant monomer comprising hydrophobic and hydrophilic functional groups, wherein said hydrophobic functional group comprises a polymerizable group within it, is useful as a binder in an ink jet ink having improved print quality.

Polymeric binders from copolymers of unsaturated carboxylic acids and surfactant monomers

An ink composition and a method for preparing the ink composition are disclosed. The ink composition provides stability, bleed resistance and lightfastness without requiring the use of a cosolvent. The composition is based on a polymeric dispersant which is compatible with the hydrophobic surfaces of many pigments and which forms a stable dispersion of pigment in an aqueous environment. The ink composition is useful for organic and inorganic pigments.

Ink composition and method for preparing

Improved adhesion to a polyolefin, especially polypropylene, of substrates of acrylic-based or other protective polymers, in the form of a plastic film, sheet, or coating or a latex or solvent-based paint, ink, or coating is achieved by use of an intermediate layer, laminate, or veneer of a blend of segmented copolymer of a polyolefin and a poly(methacrylate) which is blended with a core/shell copolymer having a crosslinked rubber core.
