Novel photosensitive polymers having an intrinsic viscosity [ eta ] of not less than 0.10 dl/g, measured at 25 DEG C. in N,N-dimethylformamide, and consisting of 1 to 40 mol % of recurring structural elements of the formula I <IMAGE> (I) and 60 to 99 mol % of recurring structural elements of the formula II <IMAGE> (II) in which R, R', R'', X, Z and Z1 are as defined in patent claim 1, are described. The polymers according to the invention can be partially complexed with metal ions of a metal of group VIII or Ib of the periodic table. In not less than 20% of the structural elements of the formula II, Z1 is -COO-C2-12-alkylene-OH, -COO(CH2CH2O)pH, -COO[CH2CH(CH3)O]pH, hydroxymethylphenyl, -CONH-C1-4-alkylene-OH or -COO-C1-4-alkylene-N(Q')(Q''), where p=2-4. The polymers according to the invention can be used, inter alia, for producing images, in particular for the construction of electrically conductive coatings or patterns. |
