PURPOSE: To provide a photosensitive composition material with high photosensitivity and usable for the light with the wide-range wavelength by containing a specific compound and alkali-soluble polymer. n CONSTITUTION: A compound expressed by the formula is contained in an alkali- soluble polymer such as cresol resin, where R 1 indicates alkyl group, substituted alkyl group, allyl group or substituted allyl group, R 2 indicates alkyl group, substituted alkyl group, allyl group or substituted allyl group, stil group, substituted stil group, vinyl group or substituted vinyl group, and R 3 -R 6 independently indicate hydrogen atom, alkyl group, allyl group, substituted allyl group, halogen atom or alkoxy group respectively. R 3 and R 4 , R 4 and R 5 , R 6 and R 6 may be bound to each other to form a benzene ring or a heterocycle together with carbon atom bound to them. The added quantity of the compound expressed by the formula in a photosensitive composition material is preferably set to 1-50wt.% against the whole solid of the photosensitive composite material. n COPYRIGHT: (C)1992,JPO&Japio |
