Abstract
PURPOSE: To eliminate the need for exposure despite the use of the specific Co(III) complex utilizing thermal reduction and yet enable distinct images to be obtained rapidly with slight current supply quantity or heat quantity by making combination use of alkaline metal hydroxides etc.
CONSTITUTION: The Co(III) complex such as hexammine cobalt (III) trifluoroacetate which produces basic substance through thermal reduction, the (hydr)oxide of alkaline (earth) metals or its hydrate, a material such as 1-nitroso-2-naphthol which colors or decolors by the action of the basic substance and a binder are dissolved or dispersed in a suitable solvent and the solution or dispersion is coated on a conductive substrate and is then dried. When the colored layer formed by being contacted of return circuit to said substrate is scanned and applied with voltage by a recording electrode, and coloring or decoloring trace is formed in the contact portion with the recording electrode, whereby the images are formed. In this recording material, care is not required in its handling under ordinary light or storage.
