    摘要: The photocurable silicone composition of the present invention comprises: (A) an organopolysiloxane represented by the average composition formula: R 1 a R 2 b SiO (4-a-b) /2 , wherein, R 1 is an alkenyl group having from 2 to 12 carbons, R 2 is an alkyl group having from 1 to 12 carbons, an aryl group having from 6 to 12 carbons, or an aralkyl group having from 7 to 12 carbons; provided that, at least 30 mol% of R 2 are the aryl groups or the aralkyl groups; and "a" and "b" are positive numbers satisfying: 1 ≤ a + b ≤ 2.5 and 0.001 ≤ a/(a + b) ≤ 0.2; (B) an organic compound having at least two ether bonds and at least one aliphatic carbon-carbon double bond in a molecule; (C) a compound having at least two thiol groups in a molecule; (D) a photoradical initiator having a phosphorus atom; and (E) a hindered phenol compound. The present composition solves a problem in that the part where the light is shielded stays uncured, suppresses reduction in transmittance due to coloring or haze at high temperatures or in high temperature/high humidity conditions, and achieves excellent coatability.
