摘要

PURPOSE: To produce a material excellent in chemical stability and also excellent in high resolution, high diffraction efficiency and high transparency by dry processing by constituting of a specified non-arom. thermoset epoxy oligomer, an aliphat. monomer, a photo-initiator and a sensitizing dye sensitizing the photo-initiator. ;CONSTITUTION: The non arom. thermoset epoxy oligomer which is solvent soluble and capable of cationic polymerization and expressed by formula (In the formula, R₁ and R₂ are residual groups respectively selected among hydrogen atom, methyl, ethyl and trifluoromethyl group and n is 1-20.) is incorporated. And the aliphat. monomer which is liq. at normal temp. and normal pressure and has ≥100°C b.p. at the normal pressure and has at least one ethylenic unsatd. bond capable of radical polymerization is incorporated. Moreover, the photo-initiator generating simultaneously a radical seed activating radical polymerization and cationic polymerization which are exposed to chemical radioactive rays and Bronsted acid or Lewis acid and the sensitizing dye sensitizing the photo-initiator are incorporated.;COPYRIGHT: (C)1996,JPO
