Document Type and Number:
WIPO Patent Application WO/2001/076884
Kind Code:
A1
Abstract:
A method for producing an information recording material, characterized in that (1) a coating liquid film having a plurality of layers is subjected to curtain flow coating wherein an intermediate coating liquid layer is arranged between two coating liquid layers which form a high viscosity liquid upon contacting or mixing with each other, (2) a coating liquid film having a plurality of layers is subjected to curtain flow coating wherein at least one set of adjacent layers gradually form a high viscosity liquid after contacting or mixing with each other, (3) the surface of a supporter is first coated with water or an aqueous liquid and then, before the supporter is dried, a coating liquid film having a plurality of layers is subjected to curtain flow coating, and (4) a coating liquid film having a plurality of layers is subjected to curtain flow coating, wherein a coating liquid layer containing 90 wt % or more of water is arranged as the layer nearest to the surface of a supporter. The method allows the production with good productivity of an information recording material which is excellent especially in qualities relating to application and has excellent various properties.
