  • Patent number: 6797318
    Abstract: A heat-sensitive recording material and a recording process. The heat-sensitive recording material is excellent in head-matching property and has a good coating surface without coating failure. The heat-sensitive recording material has, on a support, a heat-sensitive recording layer, a protective layer and other layers as necessary. The protective layer contains a specific aliphatic compound derivative having at least a —CONH— structure and/or a water-soluble polymer having a specific repeating unit.

  • Publication number: 20030203136
    Abstract: The invention provides a heat-sensitive recording material including, as a heat-fusible substance, a derivative of a higher fatty acid in which one or more hydrogen atoms in an alkyl group are replaced with hydroxyl groups, and a preferable derivative of the higher fatty acid is a derivative of 12-hydroxystearic acid. The invention also provides a heat-sensitive recording method, which includes the steps of applying thermal energy via a thermal head having an uppermost layer whose carbon content is 90% or higher, to a heat-sensitive recording material.

  • Patent number: 6395679
    Abstract: A heat-sensitive recording material is provided which has an excellent head matching performance and a surface which is coated well without any coating defects. A method for producing the heat-sensitive material is also provided. The heat-sensitive recording material includes a substrate, and a heat-sensitive recording layer and a protective layer disposed on the substrate in that order. The protective layer is formed by applying a coating solution for the protective layer containing a pigment, a binder, and an emulsion of silicone oil dispersed so that an average particle diameter of silicone oil is 0.15 &mgr;m or less. It is preferable that the silicone oil is at least one type of silicone oil selected from the group consisting of ether modified silicone oil, carboxy modified silicone oil and amino modified silicone oil. Further, it is preferable that the silicone oil has a viscosity within a range from 400 to 100,000 cps.
