Abstract
A method of manufacturing an inkjet recording cast-coated paper wherein a coating solution containing a pigment and a binder resin is supplied to a base paper, a treatment solution having the function of solidifying the binder resin is supplied to the coating layer while it is still wet in order to solidify the coating layer, and the wet, solidified coating layer is brought into pressure contact with the mirror surface of a heated drum and dried to obtain a cast-coated layer. According to this invention, the treatment solution is supplied by the double pond method wherein the roll is enclosed by the base paper so as to bring the wet coating layer into contact, and ponds of treatment solution are formed both before and after the coating layer comes into contact with the roll.
