UV CURABLE ADHESIVE SILICONE COMPOSITION, UV CURABLE ADHESIVE SILICONE COMPOSITION SHEET, OPTICAL SEMICONDUCTOR DEVICE AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: An UV hardening adhesive silicone composition is easy to handle and to process because the composition is in solid-state or semi solid-state of plasticity in uncured state. CONSTITUTION: An UV hardening adhesive silicone composition contains organopolysiloxane of resin structure, organohydrogenpolysiloxane of resin structure and an optical active type catalyst. The organopolysiloxane includes R^1SiO_3/2 units, R^22SiO_2/2 units and R^3aR^4bSiO_ (4-a-b)/2 units. Part of R^22SiO_2/2 units is repeatedly formed and includes a structure of the repeat counts of 5-300.The organohydrogenpolysiloxane includes R^1SiO_3/2 units, R^2_2SiO_2/2 units and R^3_cH_dSiO_ (4-c-d)/2 units. Part of R^2_2SiO_2/2 is repeatedly formed and includes a structure of the repeat counts of 5-300. The UV hardening adhesive silicone composition is in solid-state or semi solid-state of plasticity in uncured state.
