摘要:
A process for producing a coated sheet, in which there can be formed a coating layer simultaneously attaining an ink absorption rate and coating film cracking control suitable for use as an inkjet recording layer, in particular, there can be realized high gloss, high ink absorption, high printing density and high image quality required for use as a glossy inkjet recording sheet. There is provided a process for producing a coated sheet, comprising coating a support, or undercoat layer superimposed on the support, with a coating liquid containing a thermosensitive polymeric compound reversibly exhibiting hydrophilicity and hydrophobicity depending on temperature change, characterized in that the coating liquid containing a thermosensitive polymeric compound is applied concurrently with application of a treatment liquid whose temperature is in the range in which the thermosensitive polymeric compound exhibits hydrophilicity, or after the application of the treatment liquid without drying after the application.

The present invention relates to a method for producing an ink jet recording sheet characterized by including: applying a coating liquid containing at least both a temperature-sensitive polymeric compound and a pigment the temperature-sensitive polymeric compound having a temperature region where hydrophobicity is exhibited and a temperature region where hydrophilicity is exhibited, the coating liquid becoming more viscous or gelating in the temperature region where hydrophilicity is exhibited, onto either an air-permeable support or at least one undercoating layer provided on an air-permeable support in the temperature region where hydrophobicity is exhibited, to form a coating layer of the coating liquid, bringing the temperature thereof to the temperature region where the temperature-sensitive polymeric compound exhibits hydrophilicity to increase the viscosity of the coating layer or gelate the coating layer, then applying a wetting liquid containing an ink fixing agent (and colloidal particles) onto the viscosity-increased or gelated coating layer, followed by bringing the assembly into contact and press to a heated specular surface and drying to form an ink-receptive layer.
