摘要： A curable silicone composition is disclosed. The composition comprises: (A) a hydrosilylation-reactive resin-linear block copolymer type organopolysiloxane; (B) an organopolysiloxane resin containing a curing-reactive group having a carbon-carbon double bond in the molecule; (C) an organohydrogenpolysiloxane; and (D) a hydrosilylation reaction catalyst. An absolute value (ΔRI) of a difference between refractive indices of component (A) and component (B) measured at room temperature is less than 0.05. The curable silicone composition generally has excellent handleability, moldability, and mechanical strength (hardness, in particular) and flexibility of a cured product while achieving high transparency. Also disclosed is a resin sheet for an optical member including the composition or cured product thereof, and a light-emitting device or the like including the composition or cured product thereof.

摘要： A gas permeable ophthalmic lens material comprises a tetraethoxysilane and an ionic silane. The ionic silane comprises positive charges and negative charges. The lens made therefrom thus comprises positive and negative charges, thus the gas permeable ophthalmic lens is hydrophilic, and prevents adhesion of bacteria in allowing the surface of the human eye to breath. A gas permeable ophthalmic lens made of the gas permeable ophthalmic lens material is also provided.

摘要： Golf ball comprising a colorless coating surrounding and adjacent to a TiO2 white-pigmented layer comprising a polymeric composition that comprises throughout: (i) passivated TiO2 particulates amount of from about 1 wt. %-10 wt. % based on total weight of second polymeric composition; and (ii) silane-containing adhesion promoter(s), for example, organosilanes and/or organosiloxanes in an amount of from about 0.1 wt. % to about 5.0 wt. % of the total weight of the polymeric composition. The coating comprises a coating composition that is different than the polymeric composition and does not contain any silane-containing adhesion promoter; and there is no surface treatment with adhesion promoter at an interface between the colorless coating and TiO2 white-pigmented layer. In lieu of the colorless coating, the golf ball may include a coating that is clear tinted or translucent.
