Patent ID: 8791170

Claim:
A photocurable organopolysiloxane composition comprising: (A) 100 parts by weight of a diorganopolysiloxane having at least two silicon atoms having a hydroxyl group and/or hydrolyzable group attached thereto in one molecule; (B) 0.1 to 30 parts by weight of a complex compound, composed of titanium-(meth)acrylate-trialkoxide and b-diketone, represented by formula (3): wherein R 1 is a hydrogen atom or methyl group, R 2 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, and 2-ethylhexyl, R 3 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, 2-ethylhexyl, phenyl, and benzyl, and R 4 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, 2-ethylhexyl, methoxy, and ethoxy; and (C) 0.1 to 30 parts by weight of a silane having at least two hydrolysable groups in one molecule, represented by the following formula, and/or its partial hydrolyzate condensate: R a SiZ 4-a wherein R is an unsubstituted or substituted monovalent hydrocarbon group having 1 to 12 carbon atoms, Z independently denotes a hydrolyzable group selected from the group consisting of alkoxy groups, alkoxyalkoxy groups, acyloxy groups, alkenyloxy groups, ketoxime groups, amino groups, aminoxy groups, and amide groups, and a is an integer of 0 to 2.
