Photosensitive resin composition

摘要

A positive type photosensitive composition for an infrared laser which comprises the following (a), (b) and (c): (a) a substance which absorbs a light and generates heat, (b) an alkaline aqueous solution-soluble resin having a phenolic hydroxyl group, and (c) a fluorine-containing polymer containing at least the following (1), (2) and (3) as a copolymer component: (1) an addition polymerizable fluorine-containing monomer having, at the side chain, a fluoro aliphatic group, (2) a monomer represented by the following formula (1), (2), (3) or (4): wherein A<1> represents a hydrogen atom, a halogen atom, or an alkyl group; W represents an oxygen atom or -NR<1>-; R<1> represents a hydrogen atom, an alkyl group, or an aryl group; R<2> represents an alkyl group which may have a substituent, or an aryl group which may have a substituent; R<3> represents an alkyl group or an aryl group; U represents a cyano group, an aryl group, an alkoxy group, aryloxy group, an acyloxymethyl group, a nitrogen-containing heterocyclic group, or -CH2OCOR<3> (wherein R<3> has the same meaning as above); and (3) an addition polymerizable monomer having an acidic hydrogen atom and an acidic group, said acidic hydrogen atom being bonded to a nitrogen atom of the acidic group.
