Abstract
A novel organosiloxane polymer is obtained by addition reaction of an organohydrogenpolysiloxane, an alkenyl-containing organopolysiloxane and an unsaturated compound of formula (3) or (4). Using the organosiloxane polymer, a photo-curable resin composition is prepared which can be exposed to radiation having a wide range of wavelength and developed to form a pattern.
