POSITIVE-TYPE RADIATION-SENSITIVE MIXTURE AND RADIATION-SENSITIVE RECORDING MATERIAL MANUFACTURED BY USING SAID MIXTURE

摘要

PURPOSE: To obtain the radiation sensitive mixture high in sensitivity and resolution and free from no corrosive action by using as a base a specified acid- producing compound in combination with a compound cross-linkable by an acid. CONSTITUTION: This radiation sensitive mixture comprises (a) the compound to be allowed to release a strong acid by action of chemical rays, (b) a compound having a C-O-C or C-O-Si bond cleavable by the acid, and (c) a polymer binder insoluble in water but soluble or swellable in an aqueous solution of alkali and the compound (a) is 1-sulfonyloxy-2-pyridone represented by the formula in which R<1> is an H atom or an alkyl group or the like; R<2> is an H or halogen atom or an alkyl group or the like; R<3> is an H atom or an alkyl group; R<4> is an H to halogen atom or a nitro or alkyl group or the like; R<5> is an H atom or an alkyl or aryl group; R<6> is an H or halogen atom or a nitro or alkoxyalkyl group or the like; R<6> is an H or halogen atom or a nitro or alkoxyalkyl group or the like; R<7> is an alkyl or cycloalkyl group or the like; (n) is an integer of 0-30; and (m) is 1 or 2.
