Abstract
A UV-curable silicone composition is disclosed. The UV-curable silicone composition comprises: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule; (B) a polysiloxane block copolymer comprising: (i) a polysiloxane block and (ii) an organo block, wherein the polysiloxane block (i) is bonded to the organo block (ii) via a specific linkage, and wherein the polysiloxane block copolymer has at least two thiol groups in a molecule; (C) a photoinitiator; and (D) an inorganic filler. The composition exhibits excellent transparency even if an inorganic filler is added to improve thixotropic property.
