Storage-stable photosensitive aminotriarylmethane/selected organic photooxidant compositions
Abstract
Abstract STORAGE-STABLE LIGHT-SENSITIVE COMPOSITIONS COMPRISING AN AMINOTRIARYLMETHANE OR SALT THEREOF AND A SELECTED PHOTOOXIDATANT. THE AMINOTRIARYLMETHANE CONTAINS AT LEAST TWO PHENYL GROUPS HAVING A DISUBSTITUTED AMINO GROUP PARA TO THE METHANE CARBON AND AN ALKYL, ALKOXY, HALO OR BUTADIENYLENE GROUP ORTHO TO THE METHANE CARBON. THE PHOTOOXIDANTS ARE HALOGENATED HYDROCARBONS, HALOGENATED SUBSTITUTED HYDROCARBONS, SULFONYL HALIDES, HALOFENYL HALIDES, TETRAARYLHYDRAZINES, BENZOTHIAZOLYL DISULFIDES, POLYMERTHACRYLALDEHYDR OR ALKYLIDENE-2,5-CYCLO-HEXADIEN-1-ONE. WHEN IRRADIATED WITH LIGHT THE PHOTOOXIDATANT BECOMES ACTIVATED AND OXIDIZES THE AMINOTRIARYLMETHANE TO ITS COLORED FORM. THE COMPOSITIONS ARE USEFUL IN PHOTOCOPYING, PHOTODUPLICATING, MICRO-IMAGING AND PHOTOGRAPHIC APPLICATIONS.
