This invention relates to ethylenically unsaturated polymerizable monomers of formula (I) wherein Y is (a, b, c, d, e, f, g, h or i) wherein A is (j, k, l, m, n or o) wherein each R is individually H, -(-CqH2q-O-)m-R2, (p), etc., which are particularly suitable for use as wet adhesion promoters and in the preparation of self-crosslinking polymers. More specifically, the polymerizable monomers of the present invention are useful to promote adhesion in polymers and copolymers, and especially in aqueous emulsion copolymer latices which are used to prepare latex paints, as well as in the preparation of self-crosslinking polymers for coating systems.

L'invention a trait à des monomères éthyléniquement non saturés, polymérisables, ayant la formule (I), Y étant (a, b, c, d, e, f, g, h ou i), A étant (j, k, l, m, n ou o), et chaque R, pris individuellement, étant H, -(-C¿q?H¿2q?-O-)¿m?-R?2¿, (p), etc.. Ces monomères sont particulièrement utiles comme promoteurs d'adhérence en milieu humide et dans la préparation de polymères autoréticulables. De façon plus spécifiques, les monomères polymérisables décrits dans la présente invention sont utiles pour favoriser l'adhérence dans des polymères et copolymères, et spécialement dans des émulsions aqueuses de copolymères au latex utilisées dans la préparation de peintures au latex, ainsi que dans la préparation de polymères autoréticulables pour successions de couches.
