摘要

PROBLEM TO BE SOLVED: To provide a UV-curable adhesive silicone composition that is in a plastic solid state or a semi-solid state in an uncured state at room temperature and therefore is easy to handle, can uniformly disperse a phosphor and cover a surface of an LED chip, and can readily form a cured layer only on a necessary portion.;SOLUTION: A UV-curable adhesive silicone composition includes: (A) an organopolysiloxane having a resin structure, consisting of R¹SiO_3/2, R²₂SiO_2/2, and R³_aR⁴_bSiO_(4-a-b)/2 units, wherein R⁴ represents a vinyl group or an allyl group, and 5 to 300 R²₂SiO_2/2 units are continuously repeated, (B) an organohydrogenpolysiloxane having a resin structure consisting of R¹SiO_3/2, R²₂SiO_2/2, and R³_cH_dSiO_(4-c-d)/2 units, wherein 5 to 300 R²₂SiO_2/2 units are continuously repeated, and (C) a photoactive catalyst, wherein the UV-curable adhesive silicone composition is in a plastic solid state or a semi-solid state in an uncured state at room temperature.;COPYRIGHT: (C)2013,JPO&INPIT
