Abstract:
A positive working photosensitive composition for an infrared laser which comprises the following (a), (b) and (c):(a) a substance which absorbs infrared rays or near infrared rays 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): CH2&boxH;CA1[COâ€”Wâ€”R2]â€ƒâ€ƒ[1]CH2&boxH;CA1[Oâ€”COâ€”R3]â€ƒâ€ƒ[2]CH2&boxH;CA1[U]â€ƒâ€ƒ[3]wherein A1 represents a hydrogen atom, a halogen atom, or an alkyl group; W represents an oxygen atom or NR1; R1 represents a hydrogen atom, an alkyl group, or an aryl group; R2 represents an alkyl group which may have a substituent, or an aryl group which may have a substituent; R3 represents an alkyl group or an aryl group; U represents a cyano group, an aryl group, an alkoxyl group, an aryloxy group, an acyloxymethyl group, a nitrogen-containing heterocyclic group, or CH2OCOR3 (wherein R3 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.
