DULL CAST-COATED PAPER AND METHOD FOR MANUFACTURING THEREOF

摘要

A cast-coated paper has, on at least one coated surface of a base paper, a coat containing pigment(s) and binder and having low gloss. The coat has a topographical surface profile in which the average peak-to-valley height Ra is from 0.1 mu m to 0.5 mu m and the maximum peak-to-valley height Rt is from 1.0 mu m to 4.5 mu m, and the wave height Wt is less than 5.0 mu m. In a process for the production of a cast-coated paper having low gloss, an aqueous coating composition which contains pigment(s) and binder is applied to at least one surface of a base paper, the coated surface is brought into contact with the surface of a heated cylinder, the coat is dried in contact with the cylinder surface and the dried paper is removed from the cylinder surface. The cylinder surface has the topographical surface profile in which the average peak-to-valley height Ra is from 0.1 mu m to 0.6 mu m and the maximum peak-to-valley height Rt is from 1.0 mu m to 5.0 mu m. The surface gloss R'(75 DEG ) of the cast-coated paper according to the invention is less than 30 (measuring angle 75 DEG ), measured according to DIN 54502.
