    摘要： A coated photosensitive material on a support comprising a layer of polyamic acids and polyamic acid aryl esters derived from tetracarboxylic acids or aminodicarboxylic acids containing a benzophenone structural unit and aromatic diamines which are substituted in both ortho-positions by at least one amino group. The material is autophotocrosslinkable and is suitable for producing protective coatings and photographic images, with corresponding polyimides being formed after irradiation by a thermal aftertreatment.
