Abstract
Sulfonyl compounds have the formula ##STR1## where n is 0, 1 or 2, Y is vinyl or a radical of the formula C.sub.2 H.sub.4 Q, where Q is hydroxyl or an alkali-detachable group, E is C.sub.3 -C.sub.6 -alkylene with or without interruption by 1 or 2 oxygen atoms in ether function, Ar is the radical of benzene or naphthalene, and R.sup.1, R.sup.2 and R.sup.3 are each hydrogen, unsubstituted or substituted C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, hydroxyl, halogen, nitro, amino, hydroxysulfonyl, carboxyl, carbamoyl, sulfamoyl, cyano or a radical of the formula (NH--).sub.m (CH.sub.2 --).sub.q SO.sub.2 --Y, where m is 0 or 1, q is 0, 2 or 3, and Y is as defined above.
