ULTRAVIOLET-CURABLE SILICONE RESIN COMPOSITION, AND IMAGE DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet-curable silicone resin composition capable of exhibiting excellent curability even when irradiated with the ultraviolet light emitted from an ultraviolet light source whose short-wavelength ultraviolet light intensity is comparatively low.SOLUTION: A ultraviolet-curable silicone resin composition contains: (A) straight-chain polyorganosiloxane containing aliphatic unsaturated groups; (B) polyorganosiloxane having a viscosity at 23°C of 10-10,000 cP and containing mercaptoalkyl groups bonded to silicon atoms; (C) an acylphosphine oxide-based photoreaction initiator; and (D) a compound which exhibits compatibility to (A), (B) and (C) and has a boiling point of ≥200°C. A ratio of the number of the mercaptoalkyl groups in (B) to the number of the aliphatic unsaturated groups in (A) is 0.1-10. (C) accounts for 0.1-0.5 wt.% and (D) accounts for 0.1-2.0 wt.% of the total weight of (A) to (D).
