Title:
ADHESIVE COMPOSITIONS CONTAINING STABLE AMINO-CONTAINING POLYMER LATEX BLENDS
Document Type and Number:
WIPO Patent Application WO2001090272
Kind Code:
A3
Abstract:
This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured. The latex is useful in variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like.
