Abstract:
1. A photo-curable resin composition comprising (A) a silicone-containing polymer comprising recurring units of the general formula (1) and having a weight average molecular weight of 3,000 to 500,000, wherein R 1 to R 4 are each independently a monovalent C 1 -C 8 hydrocarbon group, m is an integer of 1 to 100, a, b, c and d each are 0 or a positive number, a+b+c+d=1, X is a divalent organic group of the general formula (2), and Y is a divalent organic group of the general formula (3), wherein W is a divalent organic group selected from the following: n is 0 or 1, R 5 and R 6 are each independently a C 1 -C 4 alkyl or alkoxy group, k is independently 0, 1 or 2, wherein V is a divalent organic group selected from the following: p is 0 or 1, R 7 and R 8 are each independently a C 1 -C 4 alkyl or alkoxy group, and h is independently 0, 1 or 2, (B) a photobase generator of the general formula (4) which is decomposed with radiation of wavelength 190 to 500 nm to generate a base, wherein R 9 and R 10 are each independently hydrogen or a straight, branched or cyclic C 1 -C 10 alkyl group, or R 9 and R 10 may bond together to form a nitrogen-containing aliphatic or aromatic ring of 3 to 8 carbon atoms with the nitrogen atom to which they are attached, which ring may have a substituent or contain a heteroatom, R 11 and R 12 are each independently hydrogen, a straight, branched or cyclic C 1 -C 10 alkyl group or an optionally substituted phenyl group, Z is a monovalent organic group selected from the general formulae (Z-1) to (Z-4) and (Z-12): wherein R 13 to R 45 are each independently selected from the class consisting of hydrogen, halogen, an optionally substituted, straight, branched or cyclic C 1 -C 10 alkyl group, optionally substituted C 1 -C 6 alkoxy group, optionally substituted C 2 -C 6 alkenyl group, optionally substituted C 2 -C 6 alkynyl group, and optionally substituted C 6 -C 10 aryl group, and (C) a solvent.
