Provided is a printing coated paper which is advantageous not only in that the coated paper has offset printability and causes no mottling in the printed area even in ink jet printing, but also in that the coated paper exhibits excellent rubbing resistance with respect to the printed area and excellent print density of a dye ink. The task of the present invention is achieved by a printing coated paper having a coating layer comprised mainly of a pigment and a binder formed on at least one side of a base paper, wherein the base paper is a treated base paper which has been subjected to size press using a treatment solution containing at least one member selected from a cationic resin and a water-soluble multivalent cation salt, wherein the total applied amount per each side of the at least one member selected from a cationic resin and a water-soluble multivalent cation salt, in terms of the solids content, is in the range of from 0.1 to 5.0 g/m.sup.2, and wherein the at least one pigment in the coating layer is ground calcium carbonate having an average particle diameter of 0.1 to 0.28 μm, wherein the amount of the ground calcium carbonate having an average particle diameter of 0.1 to 0.28 μm contained in the coating layer is in the range of 60 parts by mass or more, relative to 100 parts by mass of the total of the pigment(s) in the coating layer.

The present invention relates to a press-heating gas grafting hydrophobization apparatus, and a hot water-resistant paper and an oil-absorbing paper manufactured using the press-heating gas grafting hydrophobization apparatus. In the press-heating gas grafting hydrophobization apparatus according to the present invention, since a non-air-permeable dryer belt is provided surrounding and pressing a drying roller to prevent dissipation from a base material of a fatty acid chloride vaporized by the drying roller, the press-heating gas grafting hydrophobization apparatus has an advantage of improving efficiency of a gas grafting reaction. Therefore, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, the reaction amount of fatty acid chloride per unit area can be remarkably improved.
