Abstract:
A method of coating a substrate by(1) applying a coating composition comprising:(a) a crosslinker component comprising a polyfunctional glyoxylated compound of the Formula I ##STR5## wherein n is a whole positive integer of at least 2; wherein Y is ##STR6## wherein A is --NH-- or --O--; wherein R is the residue of a poly (active hydrogen group)-containing compound after abstraction of n active hydrogen-containing groups, wherein the active hydrogen groups are selected from hydroxyl, amino and aminohydroxyl groups;wherein R.sup.3 is hydrogen, an alkyl group having from 1 to 4 carbon atoms, a hydroxymethyl or an alkoxymethyl group having 2 to 4 carbon atoms; andwherein each R.sup.4 is H or an alkyl group having from 1 to 6 carbon atoms; and(b) a polyfunctional active hydrogen-containing material containing on average of at least two groups with active hydrogen functionality and/or functionality convertible thereto; and(2) heat curing the so-applied coating.
