A siloxane polymer comprising polysiloxane, silphenylene, isocyanuric acid, and polyether skeletons in a backbone and having an epoxy group in a side chain is provided. A photosensitive resin composition comprising the siloxane polymer and a photoacid generator is coated to form a film which can be patterned using radiation of widely varying wavelength. The patterned film has high transparency and light resistance. |
