ABSTRACT:
High quality cast-coated paper is obtained with high productivity by applying an aqueous coating composition containing a coating pigment and a binder to the surface of base paper by means of a blade coater to form an undercoating layer, the application rate being from 5 to 25 g/m.sup.2 on dry basis per side; then applying to said undercoating layer an aqueous coating composition containing a coating pigment and a polymer latex having a glass transition point of 38.degree. C. or higher to form an overcoating layer, drying said overcoating layer at a temperature below the glass transition point of the latex in said overcoating layer; and subjecting it to mirror finish treatment at a temperature higher than said glass transition point.
