ABSTRACT:
The subject of the present invention is a composition comprising at least one masked or unmasked polyisocyanate in the form of an aqueous emulsion and at least one polyhydroxylated polymer, advantageously a polyol, in the form of a second aqueous dispersion. This composition is further defined in that the polyol content, expressed in mass per cent, is at least equal to 35-0.75 R and the polyol content, expressed in mass per cent, does not exceed 45-2 R with R equal to the ratio of the mean size (d.sub.50) of the emulsion to that of the polyol dispersion.
