Abstract:
A positive photosensitive composition comprising (A) a compound which generates an acid upon irradiation with actinic rays or a radiation, (B) a resin having monovalent polyalicyclic groups represented by at least one of formulae (I), (II), and (III) and further having groups which decompose by the action of an acid to enhance solubility of the resin in an alkaline developing solution, and (C) compound represented by formula (CI) or (CII): ##STR86##wherein R.sub.1 to R.sub.5 may be the same or different and each represents an optionally substituted alkyl, cycloalkyl, alkenyl, acyloxy, or alkynyl group, a halogen atom, a cyano group, or a group represented by--R.sub.6 --O--R.sub.7,--R.sub.8 --CO--O--R.sub.9,--R.sub.10 --CO--NR.sub.11 R.sub.12,--R.sub.13 --O--CO--R.sub.14,--R.sub.15 --CO--X.sub.1 --A.sub.1 --R.sub.16,--R.sub.15 --CO--X.sub.1 --A.sub.2 --R.sub.17,--R.sub.15 --CO--NHSO.sub.2 --X.sub.2 --A--R.sub.17, or--COOZ,wherein R.sub.7 and R.sub.9 may be the same or different and each represents a hydrogen atom, an optionally substituted alkyl, cycloalkyl, or alkenyl group, --Z, or such a group that the --O--R.sub.7 or --CO--O--R.sub.9 functions as an acid-decomposable group which decomposes by the action of an acid to enhance solubility of the resin in an alkaline developing solution,Z is a group represented by either of the following formulae: ##STR87##wherein R.sub.19 to R.sub.26 may be the same or different and each represents a hydrogen atom or an optionally substituted alkyl group and a and b each represents 1 or 2,R.sub.11, R.sub.12, and R.sub.14 may be the same or different and each represents a hydrogen atom or an optionally substituted alkyl, cycloalkyl, or alkenyl group, provided that R.sub.11 and R.sub.12 may be bonded to each other to form a ring,R.sub.6, R.sub.8, R.sub.10, and R.sub.13 may be the same or different and each represents a single bond or an optionally substituted alkylene, alkenylene, or cycloalkylene group,R.sub.15 represents a single bond or an optionally substituted alkylene or cycloalkylene group,X.sub.1 represents an oxygen atom, a sulfur atom, or --NH--,X.sub.2 represents a single bond or --NH--,A represents one member or a combination of two or more members selected from the group consisting of a single bond and optionally substituted alkylene, ether, thioether, carbonyl, ester, amide, sulfonamide, urethane, and urea groups,A.sub.1 represents one member or a combination of two or more members selected from the group consisting of optionally substituted alkylene, ether, thioether, carbonyl, and ester groups,A.sub.2 represents one member or a combination of two or more members selected from the group consisting of optionally substituted alkylene, ether, thioether, carbonyl, ester, amide, sulfonamide, urethane, and urea groups, provided that at least one A.sub.2 is selected from sulfonamide, urethane, and urea groups,R.sub.16 represents --COOH, --COOR.sub.9, --OR.sub.7, --COOZ, --CN, a hydroxyl group, or --CO--NH--SO.sub.2 --R.sub.30, andR.sub.17 represents --COOH, --COOR.sub.9, --OR.sub.7, --CN, a hydroxyl group, --CO--NH--R.sub.30, --CO--NH--SO.sub.2 --R.sub.30, --Z, or an optionally substituted alkyl, cycloalkyl, or alkoxy group,wherein R.sub.30 represents an optionally substituted alkyl or cycloalkyl group andl, m, n, p, and q may be the same or different and each represents 0 or an integer of 1 to 5,provided that when l, m, n, p, or q is 2 or larger, the plural substituents with respect to each of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 may be the same or different; two of the plural substituents, which are present on the same carbon, in combination may represent a carbonyl group (.dbd.O) or a thiocarbonyl group (.dbd.S); two of the plural substituents, which are bonded to adjacent carbon atoms, may represent a double bond between the carbon atoms; and two of the plural substituents may be bonded to each other to form a ring,the bond for external linkage of each monovalent polyalicyclic group represented by formula (I), (II), or (III) being located in any position in the polycyclic hydrocarbon structure; ##STR88##wherein in formula (CI), X represents O, S, --N(R.sub.53)--, or a single bond, R.sub.51, R.sub.52, and R.sub.53 each represents a hydrogen atom or an alkyl group, R' represents such a group that the --COOR' functions as an acid-decomposable group, and R represents a residue having a valency of n1 and comprising either an internally crosslinked hydrocarbon group or a naphthalene ring, andin formula (CII), R.sub.60 represents a hydrogen atom or an alkyl group, R.sub.61 represents such a group that the --O--R.sub.61 functions as an acid-decomposable group, m1, n1, and p1 may be the same or different and each represents an integer of 1 to 4, and q1 represents an integer of 0 to 10.
