A coated printing paper offering high gloss, no mottled impression, sufficiently practical levels of printability in terms of ink-drying property and surface peel strength, and good productivity achieved by elimination of deposits on the calender rolls, wherein the coated printing paper comprises a base paper and a coating layer comprising pigment and adhesive formed on the base paper, and wherein a surface layer comprising 100 weight-parts of thermoplastic copolymer with a glass-transition temperature of 80&#xb0; C. or above and 3 to 100 weight-parts of surface sizing agent of styrene-acrylic, olefin or styrene-maleic acid copolymer type is formed on the coating layer.

Coated paper for printing

A coated sheet for web offset printing which includes a pigment coating layer containing a pigment and an adhesive formed on a base paper, and a surface layer containing a surface-sizing agent and a plastic pigment formed on the pigment coating layer.

Coated sheet for rotary offset printing

A coated paper for gravure printing that offers good gravure printability resulting from reduced missing dots while at the same time achieving high sheet gloss, wherein the paper comprises a base paper and a coating layer containing a pigment and an adhesive. This paper also contains a compound having an effect of inhibiting the binding between pulp fibers, wherein the compound, when added to 0.3 weight-part per 100 parts of bone-dry pulp, will reduce the tensile strength of the paper by five % to 40% (as measured in accordance with JIS P 8133).
