Radiation-sensitive coating agent Abstract Polyimides of aromatic tetracarboxylic acid deriva- tives and aromatic diamines where both ortho-positions rela- tive to a phenylene radical bonded to an imide group of the polymer are substituted by alkyl groups can be radiation- crosslinked with organic chromophoric polyazides. Solutions of said polyimides and polyazides in organic solvents can be used as radiation-sensitive coating agents for, for example, preparing insulating and protective films and in particular for producing printed circuits and integrated circuits.
