Abstract
Disclosed is a method of producing, with good productivity, information recording materials such as a thermal recording material and an inkjet recording material excellent in coating properties and excellent in various properties. The method comprises forming a coating composition film made of a plurality of coating color layers on a substrate by curtain coating and drying the coating composition film to form part or all of layers for forming an information recording material, and either (1) adjusting the viscosity of each of the coating colors for a plurality of the coating color layers to at least 100 mPa·s and controlling the surface tension of the coating color for a lowermost layer to 18 to 45 mN/m, or (2) controlling the density of the coating color for a layer to be positioned above not to exceed 140% of the density of the coating color for an adjacent layer to be positioned below. The present invention has been completed on the basis of the above findings.
