Abstract:
     The invention is a record film. There is a layer of developer on its carrier. The developer can give stain reaction with oil-soluble basic dyes and rapidly form a trace, of which the color and lustre density and the light-fastness is improved. Besides the conventional components, such as the binder, brightner, filler and so forth in the coating of the film, there are: (a) phenolic polymers of low polymerization degree, (b) aromatic carboxylic acid, and (c)inorganic magnesium compound, of which the MgO and Mg(OH)2 is preferably. When the component ratio of (a) (b) (c) is low polymer 50 parts, acid 1.0-2.5 parts and magnesium compound 10-40 parts, the result is most satisfactory.
