ABSTRACT:
The compounds according to the invention have the formulae Ia or Ib ##STR1## in which Y is a divalent organic radical and Z is --NH.sub.2, --NH-alkyl having 1-4 C atoms, --OH, --COOH, --COCl, --O--CO--CH.dbd.CH.sub.2, ##STR2## --COO--CH.dbd.CH.sub.2 or --O--CH.dbd.CH.sub.2. These novel 3- or 4-azidophthalic acid derivatives may be used for the preparation of photo-crosslinkable polymers. Compared to corresponding photosensitive polymers of the prior art, these novel polymers have the advantages that they are even more photosensitive and that they also absorb in the long wavelength UV region (at wavelengths greater than 320 nm).
