  • Patent number: 8025924
    Abstract: The present invention aims to provide a cast-coated paper having good sheet gloss, printability and productivity and a process for preparing it. Herein disclosed is a cast-coated paper obtained by applying a cast coating layer comprising a pigment and an adhesive on a base paper, and pressing and drying the cast coating layer in the wet state against a heated mirror finishing surface to finish it, characterized in that the cast coating layer contains 50 parts by weight or more of a kaolin having a particle size distribution containing 65% by volume or more of particles in the range of 0.4-4.2 ?m per 100 parts by weight of inorganic pigments and further contains a plastic pigment; as well as a process for preparing it.
    Type: Grant
    Filed: October 15, 2004
    Date of Patent: September 27, 2011
    Assignee: Nippon Paper Industries Co., Ltd.

  • Patent number: 7208068
    Abstract: A dull coated printing paper that is bulky (low in density) having a density of 0.90 to 1.15 g/cm3 and yet offers excellent pliability, superior surface smoothness, high degree of print gloss and minimal small-scale gloss variations in the image area are obtained by forming a coating layer comprising a pigment and an adhesive on a base paper which contains an organic compound having an action to inhibit binding between pulp fibers and then carrying out calender treatment at a line pressure for the treatment of 50 to 150 kg/cm.
