  • Method for Producing Ink Jet Recording Sheet and Ink Jet Recording Sheet
    Publication number: 20080038491
    Abstract: 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
