Patent ID: 7686878

Claim:
A coating composition which comprises an adhesion-promoting amount or crosslinking effective amount of a silane which, upon hydrolysis of its hydrolyzable sites, produces an organic compound selected from the group consisting of acetylenic glycols, polyalkoxylated variants of acetylenic glycols, hydroxycarboxylic acids and ester alcohols wherein the silane has the general formula: Y[-G(—SiX u Z c w ) s ] r (Formula 1) wherein each occurrence of G is independently chosen from a set of groups comprising a polyvalent group derived by substitution of one or more hydrogen atoms of an alkyl, alkenyl, aryl or aralkyl group, or a molecular component which can be obtained by removal of one or more hydrogen atoms of a heterocarbon, with G containing from about 1 to about 30 carbon atoms; each occurrence of X is independently selected from the group consisting of a monovalent alkoxy group derived from acetylenic glycols, polyalkoxylated variants of acetylenic glycols, hydroxycarboxylic acid and ester alcohols; each occurrence of Z C is independently selected from the group consisting of —O(R 10 CR 11 ) f O—, —NR 4 -L 1 -NR 5 —, and —OC(═O)R 10 CR 11 C(═O)O—, wherein each occurrence of R 10 and R 11 is independently R and each occurrence of L 1 is independently G; each occurrence of R is chosen independently from the set of groups consisting of hydrogen, and organic groups having 1 to about 20 carbon atoms and selected from straight alkyl, cyclic alkyl, branched alkyl, alkenyl, aryl, aralkyl, an ether, a polyether and molecular components obtained by removal of one or more hydrogen atoms of a heterocarbon; each occurrence of R 4 and R 5 is independently given by one of the structures listed for R each occurrence of the subscript f is an integer from 1 to about 15; each occurrence of the subscript u is an integer equal to 1; each occurrence of the subscript w is an integer equal to 1; each occurrence of the subscript r is an integer from 1 to about 6; each occurrence of the subscript s is an integer from 1 to about 6; and, each occurrence of Y is a functional group of valence r.
