Concerning a process for producing an information recording material having an information recording layer formed on a substrate, there are disclosed (1) a method of curtain-coating a coating composition film comprising two coating solution films of which the viscosity increases when the two coating solution films are brought into contact, or mixed, with each other and an intermediate coating solution film that is for isolating said two coating solution films one from the other and is provided between said two coating solution films, (2) a method of curtain-coating a coating composition film comprising at least one set of adjacent two layers of which the viscosity increases with the passage of time when the two layers are brought into contact, or mixed, with each other, (3) a method of applying water or an aqueous solution to a substrate surface and curtain-coating the substrate in a non-dry state with a coating composition film made of a plurality of layers, and (4) a method of curtain-coating a coating composition film having, as a lowermost layer, a coating solution having a water content of at least 90 % by weight. According to the method of the present invention, there can be produced an information recording material particularly excellent in quality of applied layers and excellent in various properties with good productivity.
