Claim:
A cross-linkable composition comprising: a) a saccharide-siloxane copolymer; b) a crosslinking agent; and c) optionally, solvent, wherein the saccharide-siloxane copolymer has the following formula: R 2 a R 1 (3-a) —SiO—[(SiR 2 R 1 O) m —(SiR 1 2 O) n ] y —SiR 1 (3-a) R 2 a wherein each R 1 can be the same or different and comprises hydrogen, C 1 -C 12 alkyl, an organic radical, or R 3 -Q, Q comprises an epoxy, cycloepoxy, primary or secondary amino, ethylenediamine, carboxy, halogen, vinyl, allyl, anhydride, or mercapto functionality, m and n are integers from 0 to 10,000 and may be the same or different, each a is independently 0, 1, 2, or 3, provided that if a is 0 then m is from 1 to 10,000 and if m is 0, then a is 1, 2 or 3, y is an integer such that the copolymer has a molecular weight less than 1 million, R 2 has the formula Z-(G 1 ) b -(G 2 ) c , and there is at least one R 2 per copolymer, wherein G 1 is a saccharide component comprising 5 to 12 carbons, b+c is 1-10, b or c can be 0, G 2 is a saccharide component comprising 5 to 12 carbons additionally substituted with organic or organosilicon radicals, Z is the linking group and is independently selected from the group consisting of: —R 3 —NHC(O)—R 4 —; —R 3 —NHC(O)O—R 4 —; —R 3 —NH—C(O)—NH—R 4 —; —R 3 —C(O)—O—R 4 —; —R 3 —O—R 4 —; —R 3 —CH(OH)—CH 2 —O—R 4 —; —R 3 —S—R 4 —R 3 —CH(OH)—CH 2 —NH—R 4 —; and —R 3 —N(R 1 )—R 4 , and R 3 and R 4 are divalent spacer groups comprising (R 5 ) r (R 6 ) s (R 7 ) t , wherein at least one of r, s and t must be 1, and R 5 and R 7 are independently an alkylene group of 1 to 12 carbons or a group of formula (R 9 O) p wherein p is any integer 1-50, each R 9 is a divalent organic group of 1 to 12 carbons and each R 9 O may be the same or different, R 6 is —N(R 8 )—, where R 8 is H or C 1 -C 12 alkyl, and at least one of R 3 and R 4 must be present in the linking group and may be the same or different, wherein the saccharide-siloxane copolymer comprises a reaction product of a functionalized organosiloxane polymer and at least one polyhydroxy-functional saccharide such that the organosiloxane is covalently linked via the linking group, Z, to the at least one polyhydroxy-functional saccharide.
