  • Patent number: 7361713
    Abstract: 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.
