ABSTRACT:
Oxime sulfonates of the formula I ##STR1## in which m is 0 or 1 and n is 1 or 2, R.sup.1 and R.sup.2 are monovalent radicals or, together with the atoms to which they are linked, form a ring system, and R.sup.3 is the n-valent radical of a mono- or di-sulfonic acid, can be split photochemically to give the free sulfonic acid. They can therefore be used as latent acid catalysts for combined radiation curing and heat curing of acid-curable finishes.
