Patent ID: 8211956

Claim:
Adhesion-promoter composition containing: (i) at least one alkoxysilane monomer of the general formula R 1 n Si(OR 2 ) 4-n (I), in which R 1 represents a residue which has at least one polymerizable group, R 2 represents a C 1 to C 8 alkyl residue and n is 1, 2 or 3, wherein the residues R 1 and R 2 can each be the same or different; (ii) at least one phosphoric acid ester monomer of the general formula O═P(OR 3 ) m (OR 4 ) 3-m (II), in which R 3 represents a residue which has at least one polymerizable group, R 4 represents a residue selected from H, silyl, and C 1 to C 16 alkyl and m is 1 or 2, wherein the residues R 3 and R 4 can each be the same or different; (iii) at least one sulphur-containing monomer which is selected from the group consisting of lipoic acid 2-ethoxycarbonylallyl ester (LSEAE) and 2,2-bisacryloylamino diethyldisulphide (BAADS); and (iv) organic solvent.
