Abstract:
The present invention provides alkoxylated polymers. The alkoxylated polymers have two or more alkoxylated sites. The alkoxylated polymers can comprise any monomers and/or oligomers that contain one or more functional groups with an active hydrogen. The alkoxylated polymers are useful in any application for which polymers are generally used. For example, the alkoxylated polymers are useful as additives in ink and coating compositions.
Abstract:
A water based dual crosslinked resin and printing inks derived therefrom containing (a) a water borne epoxy/ester/acrylate copolymer having reactive keto groups and thylenic unstaruation and (b) a poly(urethane/urea) having terminal amino groups; whre the crosslinking occurs between the reactive keto and terminal amino groups. The resin also contains onium carboxylate salt groups derived from carboxylic acid groups, ammonia or volatile amine so that the crosslinking system is neither neutral nor basic.
Abstract:
The present invention provides a water-based black ink, utilizing biochar as the black pigment. The black inks of the invention contain high bio-renewable carbon content (BRC), preferably 100% BRC. The inks exhibit the physical properties required to perform according to the requirements of rotogravure and flexographic printing.
Abstract:
This development pertains to polyurethane resins for producing stable pigment dispersions that are compatible with co-solvents and humectants used in aqueous inkjet inks. Inks with improved flow in printhead and penetration of substrate may be obtained.
Abstract:
The present invention provides novel anionic modified rosin ester resins having a high BRC content, up to 100% BRC. The resins of the present invention are useful as emulsion, dispersion, or solution resins. High BRC content pigment grind vehicles, coatings, and finished inks can be prepared using the resins of the present invention. Advantageously, the finished inks of the present invention have equal to or superior properties compared to current commercially available inks sold as sustainable products, but having little to no BRC content. The present invention represents a significant step towards developing sustainable inks and coatings that are better for the environment.
Abstract:
The present invention is directed to a water-based printing ink or coating composition comprising an acrylic resin emulsion and an epoxy ester resin dispersion. The present invention also provides a process for preparing the printing ink or coating composition comprising forming an emulsion of an acrylic resin having the general formula I by copolymerizing monomers in water, forming an epoxy ester resin dispersion by adding the epoxy ester resin to a solvent and combining the acrylic resin emulsion and the epoxy resin ester dispersion to provide the composition. Finally the present invention provides a process for preparing an article with a coating or an ink printed thereon which comprises applying the ink or coating composition to a surface of an article and drying the composition. The compositions exhibit a high degree of alkali resistance, acid resistance and/or water softener resistance.
Abstract:
A method of preparing a polyurethane resin is disclosed which consists of reacting in the absence of an independent catalyst at least one diisocyanate compound with at least two diisocyanate reactive compounds such that at least one of the diisocyanate reactive compounds contains at least one isocyanate reactive group and a carboxylic acid functional group.
Abstract:
Described herein is a polar non-aqueous dispersion comprising polar polymeric microparticles in a polar non-aqueous medium, the polar polymeric microparticles being insoluble in the medium and being produced by dispersion polymerization of vinyl monomers such as acrylate monomers in the medium in the presence of a polymeric acrylic stabilizer. Inks, coatings and overprint varnishes are formulated that employ the polar non-aqueous dispersion. Such inks, etc., exhibit superior chemical resistance properties, for example in one-part and two-part systems.
Abstract:
The present invention concerns polyester resins of General Formula I (HO-[R 1 R 2 C(CH 2 -)] a [- OCOC x H y CO 2 -] b [-C p H z O-] c -H) or General Formula II (HO-[R 1 R 2 C(CH 2 -) 2 ] a [-OCOC x H y CO 2 -] b [- CH 2 CR 3 (CO 2 H)CH 2 O] d -H), wherein R 1 , R 2 , a, b, c, d, x, y, p, and z are as defined herein, for use in inks and coating compositions. The polyester resins of the present invention are particularly, but not exclusively, suitable to enhance the adhesion between a printing ink or coating composition and a substrate, especially a plastic substrate, to which it is applied. The polyester adhesion promoters of the invention are compatible with urethane-based inks and coating compositions.

Abstract:
Solvent based poly(urethane/urea) resins suitable for formulating flexographic and gravure laminating printing ink and coating compositions formed from a poly(urethane) prepolymer solution made from a blend of polymeric diols and diols reacted with diisocyanates and then with diamine in an organic solvent. The resin is prepared by adding the poly(urethane) prepolymer solution at a controlled rate to the diamine in a organic solvent which allows a resin solution to be formed, which may be used in the formulation of laminating printing ink and coating compositions without the need for adjuvants, grinding in polyvinyl butyral or blending with nitrocellulose base.
