Abstract: This invention relates to improved flexible laminates formed from at least one corona treated polyolefin or polyester film bonded to another polymeric or cellulosic film via an aqueous based laminating ink. The improvement in the flexible laminates resides in the aqueous based emulsion used to print and bond the respective films. The aqueous based emulsion is comprised of an acrylic interpolymer prepared by emulsion polymerizing alkyl(meth)acrylates, .alpha.,.beta.-unsaturated olefins, such as styrene and suitably substituted styrenes, and/or .alpha.,.beta.-unsaturated nitrites, such as acrylonitrile, with an amino(meth)acrylate, an amino (meth)acrylate or vinyl amine.

Abstract: The invention relates to improved carboxylated styrenic polymers suited for use in the graphic arts industries as dispersants for pigments and varnishes. The base polymer comprises polymerized units of styrene and an .alpha.,.beta.-unsaturated monocarboxylic acid, with said polymer incorporating hydrophilic functionality. The improvement in the polymer composition comprises the polymerized incorporation of hydrophilic functionality based upon the half acid ester of an .alpha.,.beta.-unsaturated dicarboxylic acid or anhydride thereof and a polyethylene glycol monoether having greater than three ethylene oxide units. The half ester not only provides surfactant properties to the polymer through the incorporation of the polyethylene glycol ether but also provides carboxyl functionality necessary for water dispersibility. The number average molecular weight is from 1,500 to 20,000 and the acid numbers for these polymers typically range from 125 to 300.

Abstract: This invention relates to improved flexible laminates formed from at least one corona treated polyolefin or polyester film bonded to another polymeric or cellulosic film via an aqueous based laminating adhesive. The improvement in the flexible laminates resides in the aqueous based laminating adhesive used to bond the respective films. The aqueous based laminating adhesive is comprised of an acrylic interpolymer prepared by emulsion polymerizing alkyl (meth)acrylates, .alpha.-.beta. unsaturated olefins, such as styrene and suitably substituted styrenes, and/or .alpha.-.beta. unsaturated nitriles, such as acrylonitrile with a glycidyl (meth)acrylate and having the pendent epoxy group converted to the hydroxy amine. The preferred pendant units are hydroxy propylamine groups.

Abstract: This invention pertains to aqueous emulsions containing water insoluble, vinyl polymer particles containing polymerized Michael adduct units of N-vinylformamide and to emulsions of vinyl acetate polymers containing said Michael adducts. These latex dispersions are prepared by the emulsion polymerization of a Michael adduct of N-vinylformamide, optionally with other ethylenically unsaturated monomers, e.g., vinyl acetate.The Michael adducts of N-vinylformamide are represented by the formula: ##STR1## where R is H or CH.sub.3, X=CN, O=CR.sub.1, O=COR.sub.1 or other electron withdrawing group such as SO.sub.3 M, SO.sub.3 R.sub.1 and NO.sub.2 wherein R.sub.1 is a linear or branched alkyl, cycloalkyl, heterocyclic, arylalkyl, alkyloxy or aryl group containing between 1 and about 20 carbon atoms and substituted derivatives thereof and M is an ion.
