Abstract:
A positive photosensitive composition comprising (A) a compound which generates an acid upon irradiation with an actinic ray or radiation, and (B) a resin having a group which is decomposed by the action of an acid to increase solubility in an alkaline developing solution, wherein the resin contains a structure represented by formula (a) and at least one structure represented by the following formulae (I), (II) and (III): ##STR71##wherein R.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom or an optionally substituted straight-chain, branched chain or cyclic alkyl group, or R.sub.1 and R.sub.2 may be bonded to each other to form a monocyclic or polycyclic ring which may contain an oxygen atom, a sulfur atom, a nitrogen atom, a ketone bond, an ester bond, an imido bond or an amido bond as a linking group; R.sub.3, R.sub.4 and R.sub.5, which may be the same or different, each represents a hydrogen atom, an optionally substituted straight-chain, branched chain or cyclic alkyl or alkoxy group, or two or more of R.sub.3, R.sub.4 and R.sub.5 may be bonded to each other to form a monocyclic or polycyclic ring which may contain an oxygen atom, a sulfur atom, a nitrogen atom, a ketone bond, or an ester bond as a linking group; R.sub.15 represents a hydrogen atom, a halogen atom, a cyano group, an alkyl group or haloalkyl group; X represents a single bond or a divalent linking group, or X and either or both of R.sub.1 and R.sub.2 may be bonded to each other to form a monocyclic or polycyclic ring; Y represents-an oxygen atom, a sulfur atom, --NH--, --N(OH)-- or --N(alkyl)--; and n represents an integer of from 1 to 3; and wherein the composition further comprises (F) a fluorine-base and/or silicon-base surface active agent.
