    摘要： The present application can provide a polyorganosiloxane and a release composition that can form a release layer capable of securing solvent resistance by maximizing a bonding force between a base film and the release layer. Also, the present application can provide a polyorganosiloxane and a release composition that can form a release layer capable of having an appropriate peel force even under room temperature and high temperature conditions, having a little change in the peel force even under high temperature and ultraviolet irradiation conditions, and securing an excellent residual adhesion rate. In addition, the present application can provide a release layer, and a release film and a pressure-sensitive adhesive film comprising the release layer as applications of the polyorganosiloxane and the release composition.

    摘要： A silicone gel composition of the present invention contains the following components: A 100 parts by mass of an organopolysiloxane that is curable by an addition reaction; B. 0.01 to 10 parts by mass of an unsaturated hydrocarbon compound having one alkenyl group per molecule; and C. an addition reaction curing catalyst in a catalytic amount. The unsaturated hydrocarbon compound is at least one selected from the group consisting of an α-olefin that is liquid at room temperature (25°C) and does not volatilize or decompose at 100°C and α-methylstyrene. A silicone gel sheet of the present invention is obtained by molding the silicone gel composition into a sheet, and curing the sheet.
