Abstract:
A positive-working photosensitive composition comprising (a) a basic nitrogen-containing compound having a polycyclic structure represented by the following general formula (I), (b) at least one of compounds represented by the following general formulae (II) to (IV) which generates an acid when irradiated with actinic rays, and (c) a resin containing a group which undergoes decomposition to increase its solubility in an alkaline developer when acted on by an acid: ##STR28## wherein Y and Z may be the same or different and each represent a straight-chain, branched or cyclic alkylene group which may contain a hetero atom or may be substituted; ##STR29## wherein R.sup.1 to R.sup.37 each represent a hydrogen atom, straight-chain, branched or cyclic alkyl group, straight-chain, branched or cyclic alkoxy group, hydroxyl group, halogen atom or --S--R.sup.38 in which R.sup.38 represents a straight-chain, branched or cyclic alkyl or aryl group; and X.sup.- represents an anion of benzenesulfonic acid, naphthalenesulfonic acid or anthracenesulfonic acid having at least one group selected from the group consisting of branched or cyclic alkyl or alkoxy groups having 8 or more carbon atoms, at least two groups selected from the group consisting of straight-chain, branched or cyclic C.sub.4-7 alkyl or alkoxy groups or at least three groups selected from the group consisting of straight-chain, branched or cyclic C.sub.1-3 alkyl or alkoxy groups or an anion of benzenesulfonic acid, naphthalenesulfonic acid or anthracenesulfonic acid having at least one group selected from the group consisting of an ester group, R.sup.39 --CO-- group, R.sup.40 --CONH--X0 group, R.sup.41 --NH-- group, R.sup.42 --OCONH-- group, R.sup.43 --NHCOO-- group, R.sup.44 --NHCONH-- group, R.sup.45 --NHCSN-- group, R.sup.46 --SO.sub.2 NH-- group and nitro group in which R.sup.39 to R.sup.46 each represent a straight-chain, branched or cyclic alkyl or aryl group.
