ABSTRACT:
The dicarboxylic acid derivatives according to the invention have the following structure ##STR1## wherein X denotes O, S, (CF.sub.2).sub.m, C(CF.sub.3).sub.2 or CF.sub.2 --CF(CF.sub.3) (m=1 to 10), and R stems from the following compounds: fluoro- or trifluoromethyl- and nitro- or cyanophenols, thiophenols or -aminobenzenes, 4-hydroxy-, 4-mercapto- or 4-aminocoumarins, N-hydroxysuccinimides or N-hydroxymaleimides, 2-hydroxy- or 2-mercaptobenzoxazoles or -benzothiazoles and 1-hydroxy- or 1-mercaptobenzotriazoles.
