Abstract
The present invention relates to a one-component system based on coreactive latexes which is able to lead to coatings which are crosslinkable at room temperature and post-crosslinkable by heat treatment, the said system consisting of a mixture of two particle dispersions, (A) and (B), each obtained by aqueous emulsion polymerization of a monomer composition A and B, respectively, (a) at least one free-radically polymerizable ethylenically unsaturated monomer comprising a functional group ##STR1## where X represents O or S, which enters into the monomer composition A; and (b) at least one free-radically polymerizable ethylenically unsaturated monomer comprising a masked aldehyde functional group selected from acetal, mercaptal, mercaptol, dioxolane and dithiolane, which enters into the monomer composition B.
