摘要： This invention is directed to an improvement in acrylic based adhesives that are particularly suited for use in the application of paper and plastic labels onto glass surfaces, such as in bottle labeling. The base adhesive is comprised of an emulsion polymerized acrylic copolymer having acid functionality, e.g., carboxyl or sulfonic acid functionality; wherein the emulsion polymerization is carried out in the presence of a stabilizer system comprising a polymer containing polymerized units of carboxylic acid. The improvement for enhancing the blush resistance of the adhesive resides in incorporating a long chain crosslinking polyamine or polyamide containing residual amines.

摘要： This invention is directed to aqueous-based ethylene-vinyl acetate (EVA) polymer emulsions suited for use in heat seal applications. The EVA polymers of this invention are produced by a relatively low-pressure process, i.e., less than 2000 psig, preferably from about 1000 to about 2000 psig. The aqueous-based EVA based polymer emulsions contain crystalline segments resulting from ethylene linkages and are prepared by emulsion polymerizing ethylene and vinyl acetate, preferably with a carboxylic monomer, in the presence of a stabilizing system containing surfactant or a cellulosic protective colloid in combination with surfactant.
