Abstract
New oximsulfonate compounds of the formulae I or II, ##STR1## wherein m is 0 or 1; x is 1 or 2; R.sub.1 is, for example phenyl, which is unsubstituted or substituted or R.sub.1 is a heteroaryl radical that is unsubstituted or substituted, or, if m is 0, R.sub.1 additionally is C.sub.2 -C.sub.6 alkoxycarbonyl, phenoxycarbonyl or CN; R'.sub.1 is for example C.sub.2 -C.sub.12 alkylene, phenylene; R.sub.2 has for example one of the meanings of R.sub.1 ; n is 1 or 2; R.sub.3 is for example C.sub.1 -C.sub.18 alkyl, R'.sub.3 when x is 1, has one of the meanings given for R.sub.3, or R'.sub.3 in the formula IV and when x is 2 in the formula 1, is for example C.sub.2 -C.sub.12 alkylene, phenylene; R.sub.4 and R.sub.5 are independently of each other for example hydrogen, halogen, C.sub.1 -C.sub.6 alkyl; R.sub.6 is for example hydrogen, phenyl; R.sub.7 and R.sub.8 are independently of each other for example hydrogen or C.sub.1 -C.sub.12 -alkyl; R.sub.9 is for example C.sub.1 -C.sub.12 alkyl; A is S, O, NR.sub.6, or a group of formula A1, A2, A3 or A4 ##STR2## R.sub.10 and R.sub.11 independently of each other have one of the meanings given for R.sub.4 ; R.sub.12, R.sub.13, R.sub.14 and R.sub.15 independently of one another are for example hydrogen, C.sub.1 -C.sub.4 alkyl; Z is CR.sub.11 or N; Z.sub.1 is --CH.sub.2 --, S, O or NR.sub.6, are useful as latent sulfonic acids, especially in photoresist applications.
