Abstract
Structurally colored cross-linkable compounds usable in coating compositions of the formula: ##STR1## wherein A is a single bond, an oxygen atom or an ##STR2## group, R.sub.1 being an alkyl group containing 1 to 6 carbon atoms, .beta.-cyanoethyl, methoxymethyl, cyclohexyl, phenyl, tolyl, xylyl, monochlorophenyl or dichlorophenyl; X is the residue of a dye of the formula X(COOH).sub.n or X(AH).sub.n ; Z is the residue of a polyisocyanate Z--N.dbd.C.dbd.O).sub.p+1 ; Y is the residue of a hydroxyl compound YOH bearing q groups having a polymerizable ethylenic double bond; p is 1 or 2; n is a whole number from 1 to 4; and q is a whole number from 1 to 7, are disclosed together with methods for their preparation, their use in coating compositions and the coatings obtained thereby.
