Abstract
A silicone compound, either alone or in combination with a photoacid generator, is added to a branched polysilane compound. According to this constitution, highly reliable polymer material and polymer film can be realized which have excellent stability of refractive index against heat and high transparency and, when the photoacid generator is contained, can cause a change in refractive index upon exposure to ultraviolet light with high sensitivity and high resolution.
