Single-component system has a base of the latex coreagents leading to the crosslinkable coatings ambient temperature and post - crosslinkable by heat treatment, and their application in the field of coatings

摘要

The present invention relates to a single-component system of coreactive latexes, which may lead to the coatings which crosslink at room temperature and post - cross-linked by heat treatment, the said system being constituted by the mixture of two particle dispersions, (a) and (b), each obtained by emulsion polymerization in aqueous medium of a composition of monomers a and b, respectively, (a) at least one monomer containing ethylenic unsaturation radically polymerizable, comprising a (cf drawing in bopi) used in the composition of monomers a and (b) at least one monomer containing ethylenic unsaturation radically polymerizable, comprising an aldehyde or masked aldehyde functional group chosen from acetal, mercaptal, mercaptol, dioxolane and dithiolane contained in the composition of monomers b / p
