FIELD: physics. ^ SUBSTANCE: light-sensitive photographic material consists of a substrate saturated with a solution of light-sensitive substances in form of successively deposited derivatives of 2-amino-1,4-naphthoquinon-2-amino-(3'-acetoxyphenyl)-3-piperdino-1,4-naphthoquinone (I) and a quaternary salt of 4-(1,4-naphthoquinoyl-2-)-1,1'-dimethylpiperazonium iodide (II). ^ EFFECT: simultaneous inclusion of a cationic and neutral derivative of amino-1,4-naphthoquinone into the light-sensitive layer ensures six-fold increase in light sensitivity of the photographic material. ^ 2 cl, 1 dwg, 3 ex |
