Non-silver light sensitive compsns. - contg. a hydroxy deriv. of naphthalene, and aromatic amine, satd. halogenated hydrocarbon and a polymeric binder

Non-silver light-sensitive compsns. are comprised of (by wt.) 1-10% of a hydroxy deriv. of naphthalene (I); 29-60% of a satd. aromatic amine (II); 35-29% of a halogenated hydrocarbon (III); and 35-1% of a polymeric binder. (I) is e.g. alpha-naphthol, beta-naphthol, 1-naphtholphthalein, aminonaphthol or dihydroxynaphthalene. (II) is e.g. diphenylbenzylamine, 1-naphthylamine, indole or dibenzylaniline. (III) is e.g. carbon tetrabromide or iodoform. (IV) is e.g. polystyrene, PMMA, polyvinyl acetate or PVC. The compsns. are silver-free and have high sensitivity and resolution. They can be applied from solvent solns. to substrates such as paper, glass, porcelain, metal, ceramics, plastics, etc. By choice of the components, multicolour images can be obtd., e.g. blue with diphenylbenzylamide, red with indole, yellow with dibenzylaniline and brown with 1-naphthylamine. The prods. are useful in photography, reprography, microfilm, microelectronics etc. L'INVENTION CONCERNE LES MATERIAUX PHOTOSENSIBLES.LA COMPOSITION PHOTOSENSIBLE FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT UNE AMINE AROMATIQUE, UN DERIVE HALOGENE SATURE D'HYDROCARBURE ET UN LIANT POLYMERE, ET EST CARACTERISEE EN CE QU'ELLE CONTIENT EN OUTRE UN DERIVE HYDROXYLE DU NAPHATALENE.
