Abstract
The present invention relates to a silicone resin composition that can be used for a roll film having small birefringence, the silicone resin composition being suitable for, for example, optical applications, and a window material for an automobile, the silicone resin composition having high heat resistance, the silicon resin composition being stained at a low level, the silicone resin composition having a low thermal expansion coefficient, the silicone resin composition enabling a transparent conductive film to be stably formed, and the silicone resin composition providing good winding property. The silicone resin composition contains: A) a silicone resin mainly composed of a polyorganosilsesquioxane having a cage-type structure in a structural unit, the polyorganosilsesquioxane being represented by [RSiO3/2]n (wherein R is an organic functional group having a (meth)acryloyl group and n is 8, 10, or 12); B) an oligomer that is radically copolymerizable with the silicone resin, the oligomer containing an unsaturated group represented by —R3—CR4═CH2 or —CR4═CH2 in a molecule, and the oligomer having a urethane bond; and C) an other unsaturated compound that is radically copolymeriza…
