Abstract
Provided is a positive image forming composition which comprises (a) a compound generating an acid when exposed to light or heat and (b) a sulfonimide compound represented by the following formula (I): EQU L.sub.1 --(SO.sub.2 --NR.sub.2 --SO.sub.2 --R.sub.1).sub.n (I) wherein n is an integer from 1 to 6; R.sub.1 is an aromatic group or an alkyl group; L.sub.1 is an aromatic group or an alkyl group in the case of n=1, while it is a polyvalent organic linkage group in the case of n=2-6; and R.sub.2 is an alkoxymethyl group, an arylmethyl group, or an alicyclic alkyl group; or a polymer containing in side chains constitutional units represented by the following formula (I'): EQU --L--SO.sub.2 --NR.sup.2 --SO.sub.2 --R.sup.1 (I') wherein R.sup.1 has the same meaning as R.sub.1 in formula (I); L is a polyvalent organic group for connecting the constitutional unit of formula (I') to the polymer skeleton; and R.sup.2 has the same meaning as R.sub.2 in formula (I).
