<p>A cast coating composition contains either of calcium formate and calcium acetate and any one of zinc compounds such as zinc oxide, zinc chloride, zinc sulfate, etc., as air permeability modifiers respectively, so that the cast coating composition is applied onto a base paper (1). Next, the base paper (1) is dried by a drying machine (3) until the base paper (1) contains a predetermined rate of moisture. A rewetting liquid is applied from a nozzle (4) to the dried base paper (1) so as to moisten the base paper (1) and plasticize the coated material. The paper is then brought into contact with the surface of a mirror-finished drum (7) which is heated to a high-temperature, and pressed by a press roll (5) so as to be finished to be glossy. Particularly, as for the quantities of the air permeability modifiers to be added, it is preferably that the quantity of either of calcium formate and calcium acetate is in a range of from 0.2 parts to 1.8 parts by weight, and further the quantity of any one of zinc compounds such as zinc oxide, zinc chloride, zinc sulfate, etc., is in a range of from 0.1 part to 3.0 parts by weight, per 100 parts by weight of the pigment. Thus, high-quality cast coated paper having a high gloss without any surface defect such as pin-holes can be produced at a high speed under the production conditions having a comparatively acceptable and reasonable range in manufacturing.</p> |
