Abstract
The invention relates to novel .omega.-aminocarboxylic acid amides having the formula (I) ##STR1## wherein A is --SO.sub.2 OH or --OPO(OH).sub.2, PA1 R.sup.1 is hydrogen, an acyl group, such as benzoyl, arylsulfonyl, alkoxycarbonyl, cycloalkoxycarbonyl or aralkoxycarbonyl group or an aralkoxycarbonyl group having a halogen, alkoxy, nitro, phenylazo or alkoxyphenylazo substituent, alkyl-substituted aryloxycarbonyl or carbonyl, PA1 R.sup.2 is hydrogen or a carbonyl group, with the proviso that when R.sup.1 and R.sup.2 each stand for carbonyl, the two carbonyl groups form a ring through an intervening o-phenylene, alkylene or vinylene group when A is --SO.sub.2 OH and R.sup.1 is an acyl group such as benzoyl, aryl sulfonyl, alkoxy-carbonyl, cycloalkoxycarbonyl or aryloxycarbonyl group or an aralkoxy carbonyl group having a halogen, alkoxy, nitro, phenylozo or alkoxyphenylazo substituent or an alkyl-substituted aryloxycarbonyl group or carbonyl group, PA1 R.sup.2 is hydrogen or a carbonyl group, with the proviso that when R.sup.1 and R.sup.2 each stand for carbonyl, the two carbonyl groups form a ring through an intervening o-phenylene, alkylene or vinylene group when A is --O--P--O(OH…
