Organosiloxane polymer, photo-curable resin composition, patterning process, and substrate-protecting coat
An organosiloxane polymer comprising recurring units of the general formula (1) and having a weight average molecular weight of 1,000-500,000 is novel. R1 to R4 are monovalent hydrocarbon groups, n is an integer of 1-2,000, X has a structure of the formula: and R5 is an acrylic functional organic group of the formula: wherein R′ is H or methyl and R″ is a divalent hydrocarbon group. A photo-curable resin composition comprising the organosiloxane polymer and a sensitizer can be cured with a wide wavelength range of light.
