Abstract:
A positive-working photosensitive composition, comprising:(a) a macromolecular compound having alkali-soluble groups; and (b) a compound that has a phthalocyanine skeleton, has in its molecule at least one group which can form a bond by interaction with the alkali-soluble group in said macromolecular compound and is defined by General Formula 1 below, wherein said alkali-soluble groups of said (a) macromolecular compound is selected from the group consisting of a phenolic hydroxyl group (â€”Arâ€”OH wherein Ar is an unsubstituted or substituted divalent aryl group), a sulfonamide group (â€”SO2NHâ€”R wherein R is an unsubstituted or substituted hydrocarbon group) and an active imide group (â€”SO2NHCOR, â€”SO2NHSO2R, â€”CONHSO2R wherein R is an unsubstituted or substituted hydrocarbon group), and said photosensitive composition becomes substantially soluble in an alkali aqueous solution upon irradiation with infrared rays wherein R11 to R14, R21 to R24, R31 to R34 and R41 to R44 each independently represent a substitutable hydrogen atom, halogen atom, cyano group, alkyl group, aryl group, alkenyl group, alkynyl group, hydroxyl group, carbonyl group, thio group, sulfonyl group, sulfinyl group, oxy group, amino group, or onium salt structure, and at least one of R 11 to R14, R21 to R24, R31 to R34 and R41 to R44 is selected from the group consisting of an amino group, hydroxyl group, thio group, carbonyl group, sulfonyl group, sulfinyl group, oxy group, and onium salt structure; two or more of the R11 to R44 groups may be bonded together to form a ring; and M represents two hydrogen or metal atoms, a halometal group, or oxymetal group.
