Abstract

The invention provides compounds which are particularly valuable for use as the active ingredient in sun tan lotions and creams and the like. These compounds have the general formula: ##STR1## in which Y denotes hydrogen or the radical SO.sub.3 H or a salt thereof with an organic or inorganic base, and Z denotes the radical --CH.sub.2 Br or --CHBrBr or a radical Z' which denotes the radical --CH.sub.2 I, --CH.sub.2 R, --CHR'R', --CHO or --COOR", in which R denotes --NR.sub.1 R.sub.2, --N.sup.+ R.sub.1 R.sub.2 R.sub.3, --OR.sub.4, --OCOR.sub.5, --SR.sub.6, --CN, -COOR" or --SSO.sub.3 Na, in which R.sub.1 and R.sub.2 independently denote hydrogen, C.sub.1-18 alkyl or hydroxyalkyl, or R.sub.1 and R.sub.2, together with the nitrogen atom to which they are attached, denote a heterocyclic ring, R.sub.3 denotes C.sub.1-4 alkyl or hydroxyalkyl or sulphonatopropyl, R.sub.4 denotes hydrogen, alkyl, polyoxyethylene, aryl which is optionally substituted, menthyl or dialkylaminoalkyl, R.sub.5 denotes alkyl, alkenyl, aryl or a 5 or 6 membered heterocyclic ring which is optionally aromatic, and R.sub.6 denotes hydrogen, alkyl, carboxyalkyl, aminoalkyl, hydroxyalkyl, aryl or 3-alanyl, R' denotes -…
