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).
根据本发明,化合物具有以下的化学式Ia或Ib,其中Y是二价有机基团,Z是--NH.sub.2,--NH-烷基,含有1-4个碳原子,--OH,--COOH,--COCl,--O--CO--CH.dbd.CH.sub.2,--COO--CH.dbd.CH.sub.2或--O--CH.dbd.CH.sub.2。这些新型的3-或4-偶氮酞酸衍生物可用于制备光交联聚合物。与先前技术中相应的光敏聚合物相比,这些新型聚合物具有更高的光敏性,并且它们还吸收长波长紫外区域的光(波长大于320纳米)。
