摘要： 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.
