PURPOSE:To maintain various performances, such as profile, heat resistance and residual film ratio, and to improve a sensitivity, resolution and value by incorporating an alkali-soluble resin, quinonediazide compd. and a specific phenol compd. into the above compsn. CONSTITUTION:This compsn. contains the alkali-soluble resin, the quinonediazide compd. and the phenol compd. expressed by formula I. These compds. are obtd. by bringing 1,5-dihydroxynaphthalene and 3-hydrox-alpha-methyl styrene or 4- hydroxy-alpha-methyl styrene into reaction in the presence of an acid catalyst. The quinonediazide compd. is not particularly limited and includes, for example, 1,2-naphthoquinonediazide-4-sulfulate, 1,2-naphthoquinonediazide-5-sulfonate. The alkali-soluble resin used for the compsn. is not particularly limited and includes, for example, a polybiphenol or novolak resin, etc. |
