ABSTRACT:
A latex based adhesive comprising a first component (adhesive component) comprising an interpolymer of at least one hard monomer, at least one soft monomer, and optionally a copolymerizable carboxylic acid comonomer having a Tg of from about -70.degree. C. to about -5.degree. C. and a second polymeric component (tackifier component) that is compatible with the adhesive component having a molecular weight less than 5,000 and a Tg from about -10.degree. C. to about 50.degree. C., both the adhesive component and tackifier component having been separately prepared by emulsion polymerization techniques.
