摘要：
Aminobenzophenones have the formula ##STR1## where the ring A may be benzofused,X.sup.1 is hydrogen or hydroxysulfonyl,X.sup.2 is hydrogen, hydroxysulfonyl, hydroxysulfonylphenyl, hydroxysulfonylbenzyl or hydroxysulfonylphenylethyl,R.sup.1, R.sup.2 and R.sup.3 are each independently of the others hydrogen, halogen, C.sub.1 -C.sub.12 -alkyl, cyclohexyl or C.sub.1 -C.sub.4 -alkoxy, or one of them may also be the radical of the formula ##STR2## where L is a chemical bond, C.sub.1 -C.sub.4 -alkylene or --O--CH.sub.2 -- and Y.sup.1, Y.sup.2 and Y.sup.3 are each independently of the others hydrogen, halogen, C.sub.1 -C.sub.12 -alkyl or C.sub.1 -C.sub.4 -alkoxy and R.sup.4, X.sup.1, X.sup.2 and the ring A are each as defined above, andR.sup.4 is hydrogen or chlorine,with the proviso that X.sup.1 and X.sup.2 are not both hydrogen, their intermediates having the formula ##STR3## where L is as defined above.
