Abstract
An aqueous emulsion comprising at least one (co)polymer is provided. The (co)polymer is derived from a monomer having formula (1): EQU (R.sub.1 R.sub.2 C.dbd.CR.sub.3 --CO--L--).sub.q A(--NCOblock).sub.p(1) wherein R.sub.1, R.sub.2, and R.sub.3, which are the same or different, represent a hydrogen or a group selected from hydrocarbon chains comprising 1 to 12 carbon atoms, halogens, and electron-withdrawing functional groups; L, which is the same or different, represents a divalent hydrocarbon radical comprising 2 to 12 carbon atoms; A represents an organic backbone which has n free valencies, n is a number between 2 and 7, and is equal to p+q; NCOblock represents a protected isocyanate functional group; p is a number between 1 and 6; and q is a number between 1 and 6.
