The light-induced dimerization in anthracene containing poly-mers is accompanied by changes in the solubility of the materials. Since the photodimerization involves not only neighboring anthracene groups in the same rnacromolecule but also the groups from different macromolecules, the originally soluble polymer or copolymer becomes crosslinked and insoluble upon exposure to activating radiation. This effect can be exploited to prepare photoresists which may be utilized in common photoresist and printing processes. In operation the photoresist is imagewise irradiated, developed with a solvent and then treated as in other common printing and photoresist processes.
