본 발명은 (A) 1분자 중의 적어도 2개의 알케닐기 및 적어도 1개의 아릴기를 가지는 오르가노폴리실록산, (B) 1분자 중의 적어도 2개의 규소 원자 결합 수소 원자를 가지는 오르가노폴리실록산, (C) 1분자 중의 적어도 1개의 아릴기를 가지며, V, Ta, Nb 및 Ce으로 이루어지는 군에서 선택되는 금속 원자를 함유하는 오르가노폴리실록산, 및 (D) 하이드로실릴화 반응용 촉매로 적어도 이루어지는 경화성 실리콘 조성물에 관한 것이다. 본 발명으로 인해 열 에이징에 의해서도 크랙을 일으키는 일이 없고, 또한 황변이 적은 경화물을 형성할 수 있는 경화성 실리콘 조성물을 제공할 수 있다. The present invention relates to a curable silicone composition comprising: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule, (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule, (C) an organopolysiloxane having at least one aryl group in a molecule and containing a metal atom selected from the group consisting of V, Ta, Nb and Ce, and (D) a hydrosilylation-reaction catalyst. The present invention can provide the curable silicone composition, which does not develop a crack by thermal aging and further can form a cured material that exhibits less yellowing. Abstract (as published by WIPO) The present invention pertains to a curable silicone composition comprising at least: (A) an organo-polysiloxane having, per molecule thereof, two or more alkenyl groups and one or more aryl groups; (B) an organo-polysiloxane having, per molecule thereof, two or more silicon-bonded hydrogen atoms; (C) an organo-polysiloxane having, per molecule thereof, one or more aryl groups, and a metal atom selected from a group consisting of V, Ta, Nb and Ce; and (D) a hydrosilation reaction catalyst. The present invention is capable of providing a curable silicone composition capable of forming a cured product which exhibits minimal yellowing, without producing cracks caused by thermal aging.
