Cross-linkable surface coatings having a latex seed core and a monomer, the monomer having acid functional pendant moieties and being capable of forming a stable enamine structure by reaction with amines

摘要

A single-package aqueous polymeric initial formulation comprising: i) A polymeric ingredient having a latex seed core with a number average particle size from 20 nanometers to 60 nanometers and a polymerisable monomeric ingredient, the polymerisable monomeric ingredient having both acid functional pendant moieties and pendant moieties having the ability to form stable enamine structures by reaction with amines, the pendant moieties containing a divalent group of the structure shown: where R1 is H, alkyl or phenyl; ii) A polyfunctional amine having at least two amine functional moieties. iii) An effective amount of base to inhibit crosslinking of the polymeric ingredient with the polyfunctional amine. iv) An evaporable aqueous carrier. The seed core is of a different chemical composition than the polymerisable monomeric ingredient.
