<p>The present invention is directed to a compound of the Formula: R1-R2-R3-R4-A-(R5)n(R6)3-n wherein: A is Si or Ti; R1 is an alkenoxy, acryloxy or ethylenically unsaturated dicarboxylate group; R2 is a 2 to 18 carbon linear, branched or cyclo alkyl, alkenyl, alkynyl, acyl, aryl or poly(alkoxy) group; R3 contains a urethane, urea, or thiourethane linkage; R4 is a 2 to 18 carbon linear, branched, or cyclic alkyl, alkenyl, alkynyl, aryl or acyl non-hydrolyzable silyl linking group; R5 is a 2 to 18 carbon linear, branched, or cyclic alkyl, alkenyl, alkynyl, aryl or acyl group; R6 is any hydrolyzable silyl linking group (alkoxy, alkenoxy, or halogen); and n is 0 to 2. The present invention is further directed to an improved method of using of a compound of the above Formula as an adhesion promoter in a UV-curable composition for a surface with a free nucleophilic group. Preferably, that surface is glass. The present invention is yet further directed to an improved UV-curable coating composition, wherein the improvement comprises adding to said coating composition a compound of the above formula in an amount sufficient to promote adhesion of a coating to a surface with a free nucleophilic group.</p> |
