Patent number: 6060556Abstract: 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 pendant-functional polymer particles; and water. The waterborne pendant-functional polymer comprises at least one pendant amine reactive functional moiety selected from the group consisting of carbonate, epoxide, isocyanate, isopropenyl, carboxylic acid, and allyl groups. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne pendant-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine).Type: GrantFiled: May 21, 1998Date of Patent: May 9, 2000Assignee: Eastman Chemical CompanyInventors: Martha Jean Collins, James Wayne Taylor, David Logan Murray
