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.

Latex based adhesive prepared by emulsion polymerization

A phosphorus modified latex composition useful in the coating of substrates with inorganic fillers. A latex particle having phosphorus groups intimately bound to the particle's surface formed by the emulsion polymerization of a latex with a phosphorus compound. Also a method of preparing a composite sheet and a paper coating latex with the phosphorus modified latex is provided.
