Abstract:
A positive silicone-containing photosensitive composition which comprises:(a) a water-insoluble and alkali-soluble polymer having a structure represented by the following formula (I) and/or (II): ##STR30##wherein X represents a group selected from the group consisting of a --C(.dbd.O)--R group, a --CH(OH)--R group, and a carboxyl group, and a plurality of X's may be the same or different; R represents a hydrogen atom or a hydrocarbon group which may have a substituent; R', R"", R""', R"""" and R""""', which may be the same or different, each represents a group selected from the group consisting of a hydroxyl group, and an alkyl, cycloalkyl, alkoxyl, alkenyl, aralkyl and phenyl groups each of which may have a substituent; Y represents an alkyl group, an alkoxyl group or a siloxyl group; R.sub.0 represents a group selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted aliphatic hydrocarbon group and a substituted or unsubstituted aromatic hydrocarbon group; l, m, n and q each represents 0 or a positive integer; and p represents a positive integer;(b) a compound which generates an acid upon irradiation with actinic rays or radiation, and(c) a polymer which has a repeating unit containing a group represented by formula (III), (IV) or (V) at the side chain, and shows the enhanced solubility in an alkaline developing solution by the action or an acid: ##STR31##wherein R.sub.a, R.sub.b and R.sub.c each represents a hydrogen atom, or a hydrocarbon group which may have a substituent; and s represents an integer of 2 or more.
