This invention provides a process for producing an ink jet recording sheet characterized by comprising coating a coating liquid containing at least a temperature-sensitive polymeric compound having a temperature region where hydrophobicity is exhibited and a temperature region where hydrophilicity is exhibited, the coating liquid being thickened or gelled in the temperature region where hydrophilicity is exhibited, and a pigment onto either a gas-permeable support or at least one undercoating layer provided on a gas-permeable support at the temperature region where hydrophobicity is exhibited, to form a coating layer of the coating liquid, bringing the temperature to the temperature region where the temperature-sensitive polymeric compound exhibits hydrophilicity to cause thickening or gelation, then applying a wetting liquid containing an ink fixing agent (and colloidal particles) onto the thickened or gelled coating layer, and then pressing the assembly against a heated specular surface for drying to form an ink-receptive layer. |
