Abstract
A positive working photosensitive composition comprising a resin having repeating units represented by the following formulae (I), (II) and (III), respectively and a compound which generates an acid with irradiation of an active ray or radiation: ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group; R.sub.2 represents --C(.dbd.O)--O--C(R.sub.6) (R.sub.7) (R.sub.8) or --O--R.sub.5 --C(.dbd.O)--O--(R.sub.6) (R.sub.7) (R.sub.8); R.sub.3 represents --O--C(R.sub.6)(R.sub.7) (R.sub.8), --O--Si(R.sub.6)(R.sub.7)(Rs) or --O--C(R.sub.9)(R.sub.10)--OR.sub.11 ; R.sub.4 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, an acyl group or an acyloxy group; R.sub.5 represents an alkylene group; R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 each independently represents a hydrogen atom, an alkyl group, a cycloalkyl group or an alkenyl group, provided that at least two among R.sub.6, R.sub.7 and R.sub.8 are groups other than a hydrogen atom; R.sub.11 represents an alkyl group or an aryl group; two groups selected from R.sub.6, R.sub.7 and R.sub.8 and two groups selected from R.sub.9, R.sub.10 and R.sub.11, each two groups may be combined to form a ring; and n is an integer from 1 to 3.
