ABSTRACT:
The present invention provides N-acylidihydroresorufin derivatives of the general formula: ##STR1## wherein R.sup.1 is a lower alkyl, aryl or aralkyl radical, which can be substituted by carboxyl or sulphonic acid residues, R.sup.2, R.sup.3 and R.sup.4, which can be the same or different, are hydrogen or halogen atoms or lower alkyl or lower alkoxy radicals, Y is an --NR.sup.5 R.sup.6 or --OR.sup.7 group, wherein R.sup.5 and R.sup.6 are, in each case, hydrogen atoms or lower alkyl radicals, which can be substituted by carboxyl or sulphonic acid residues, or together represent a hydrocarbon bridge optionally interrupted by hereto atoms and R.sup.7 is a lower alkyl radical which can be substituted by a lower alkoxy or poly-lower alkoxy radical.
