Abstract: An inkjet ink binder composition including an emulsion polymer, the polymer including as polymerized units 1-10%, by weight based on dry polymer weight, of a monomer selected from the group consisting of methylol acrylamide, methylol methacrylamide, methyl acrylamidoglycolate methyl ether, acrylamidoglycolic acid, and mixtures thereof is provided. An inkjet ink composition including the emulsion polymer, a liquid medium, and a pigment and a method for improving the durability of inkjet ink printed on a substrate are also provided.

Abstract: A non-pigmented heat resistant ink composition suitable for use in ink jet printing is provided made up of cross-linked hollow micro-sphere particles. The remainder of the ink composition comprises a suitable carrier vehicle, which typically contains water, alcohols, surfactants, humectants and optionally a resin component.

Abstract: An ink composition is provided including at least one colorant, an aqueous medium, and a polymeric binder. The polymeric binder contains at least one hydrophobic monomer or fluorinated monomer as a polymerized unit. Also provided is a method inkjet printing the ink composition onto a substrate. The ink composition is suitable for providing dried ink films with improved wet rub resistance.

Abstract: Inorganic material particles are dispersed in an aqueous medium with surface charge adjusting additives to give a moderately stable slurry or pigment grind. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to give the same performance as products including inorganic material dispersed with conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance properties with like levels of inorganic material.

Abstract: A non-aqueous dispersion for modifying alkyd-containing coating formulations and a method for manufacturing the non-aqueous dispersion are provided. The non-aqueous dispersion contains from about 10 to about 60 parts by weight of a low molecular weight solution polymer, having a selected glass transition temperature greater than about -10.degree. C., and from about 90 to about 40 parts by weight of a polymer which is insoluble in the non-aqueous medium, and where the soluble polymer is attached to or adsorbed onto the insoluble polymer particles. The non-aqueous dispersion is preferably prepared by dispersion polymerization to form the insoluble polymer in a non-aqueous medium in the presence of the soluble polymer.

Abstract: This invention relates to a non-aqueous coating composition and a method for reducing the drying time of a non-aqueous coating composition by incorporating composite polymer particles having a softer, insoluble first stage and a hard second stage without adversely affecting the viscosity and pot life of the liquid coating composition and without degrading the properties of the final dry coating, including color, flexibility, impact resistance, gasoline resistance, salt spray resistance and humidity resistance.

Abstract: Novel thickening agents, useful for thickening non-aqueous solvent-containing compositions, are provided. The thickening agents are the reaction product of a polyol containing at least two hydroxyl groups; a polyisocyanate containing at least two isocyanato groups; and an active hydrogen compound. A method of thickening non-aqueous systems by admixing with the novel thickening agents is also provided.

Abstract: Low levels of surface-active, aliphatic C.sub.16 or greater hydrocarbon-type compounds are used to reduce the rate of evaporation of water from waterborne polymer products such as latex coatings. This increases the wet-edge or open time of the freshly applied coating, improves integrity and adhesion of the dried coating, and reduces skin formation in containers and on application equipment.
