PRODUCTION OF COATED PAPER
PURPOSE:To obtain a coated paper having excellent stable whiteness and color tone by using a starch paste having an extremely low degree of coloring even in the case of preserving the starch paste at a high pH and at a high temperature by stably retaining the starch paste at a low viscosity.

| description | PURPOSE:To obtain a coated paper having excellent stable whiteness and color tone by using a starch paste having an extremely low degree of coloring even in the case of preserving the starch paste at a high pH and at a high temperature by stably retaining the starch paste at a low viscosity. CONSTITUTION:This method for producing the coated paper comprises impregnating or coating base paper with a coating solution using a starch paste which is obtained by making an aqueous dispersion of starch into paste by heating and contains thiourea dioxide. The added amount of thiourea dioxide is preferably 0.05-2wt.% based on the solid content of starch. A thermally chemically denatured starch using ammonium persulfate is especially excellent in making the starch paste into paste under heating. |
