Patent ID: 8828640

Claim:
A photo-curing polysiloxane composition, comprising: a polysiloxane (A); a quinonediazidesulfonic acid ester (B); a methylene alkoxyaryl-containing compound (C); and a solvent (D) wherein said methylene alkoxyaryl-containing compound (C) is selected from the group consisting of a compound of Formula (I): wherein m is an integer ranging from 1 to 4, R 1 and R 2 are independently selected from the group consisting of a C 1 -C 6 alkyl group and a group of —CH 2 —O—X with the proviso that at least one of R 1 and R 2 is the group of —CH 2 —O—X, wherein X represents a C 1 -C 5 alkyl group, R 3 is selected from the group consisting of hydrogen, methyl, and ethyl, R 4 is selected from the group consisting of a single bond and a group having m valence with the proviso that R 4 is selected from the group consisting of a C 1 -C 6 alkyl group, a C 6 -C 12 cycloalkyl group, and hydrogen when m is 1, R 4 is a bivalent group selected from the group consisting of phenylene, —SO 2 —, when m is 2, R 4 is a trivalent group selected from the group consisting of when m is 3, and R 4 is a tetravalent group selected from the group consisting of when m is 4, wherein X 10 -X 27 are independently selected from the group consisting of hydrogen, halogen, and a C 1 -C 20 organic group, a compound of Formula (II): wherein n is an integer ranging from 10 to 35, R 5 and R 7 are independently selected from the group consisting of hydrogen, methyl, and ethyl, and R 6 represents a C 1 -C 6 alkyl group, and a combination thereof, wherein said polysiloxane (A) is a copolymer obtained by subjecting a silane monomer of Formula (III) to hydrolysis and partial condensation, Si(R a ) t (OR b ) 4−t (III) wherein t is an integer ranging from 0 to 3, R a is selected from the group consisting of hydrogen, a C 1 -C 10 alkyl group, a C 2 -C 10 alkenyl group, a C 6 -C 15 aryl group, an anhydride-substituted alkyl group, an oxetanyl-substituted alkyl group, an oxetanyl-substituted alkoxy group, a glycidyl-substituted alkyl group, and a glycidyl-substituted alkoxy group, plural R a s being identical with or different from each other when t is 2 or 3, and R b is selected from the group consisting of hydrogen, a C 1 -C 6 alkyl group, a C 1 -C 6 acyl group, and a C 6 -C 15 aryl group, plural R b s being identical with or different from each other when 4−t is 2 or 3, with the proviso that said silane monomer of Formula (III) includes at least one silane monomer selected from the group consisting of said silane monomer of Formula (III) having an anhydride group and said silane monomer of Formula (III) having an oxetanyl group.
