Claims
- 1. A process for manufacturing a coated paper used in printing, said process comprising the steps of: coating a layer containing a color-containing pigment and a water-soluble binder on a base paper surface, said binder comprising at least one member selected from the group consisting of a starch and a starch derivative; drying the coated paper surface; applying an aqueous penetrant solution to the dried coated paper surface in an amount of 1.about.1 g/m.sup.2 to redistribute the water-soluble binder in the coating layer, said aqueous penetrant solution having a penetrating force of less than 50 seconds as determined by the canvas disk method; drying the coated paper; and finishing the dried coated paper with a calender.
- 2. A process as defined in claim 1, wherein an aqueous penetrant solution with a penetrating force of less than 30 seconds is used as the aqueous penetrant solution.
- 3. The process as defined in claim 1, wherein at least one member selected from the group consisting of carboxyl methyl cellulose, hydroxy ethyl cellulose, polyvinyl alcohol, and olefin-maleic anhydride resin is contained in said water-soluble binder.
- 4. The process as defined in claim 2, wherein at least one member selected from the group consisting of carboxyl methyl cellulose, hydroxy ethyl cellulose, polyvinyl alcohol, and olefin-maleic anhydride resin is contained in said water-soluble binder.
- 5. The process as defined in claim 1, wherein said coating layer contains at least one substance selected from the group consisting of a conjugated diene-based copolymer latex, an acrylic polymer latex, a vinyl-based polymer latex, an alkali-soluble polymer, an alkali-insoluble polymer and a copolymer latex made by denaturing a copolymer latex with a functional group-containing monomer.
- 6. The process as defined in claim 2, wherein said coating layer contains at least one substance selected from the group consisting of a conjugated diene-based copolymer latex, an acrylic polymer latex, a vinyl-based polymer latex, an alkali-soluble polymer, an alkali-insoluble polymer and a copolymer latex made by denaturing a copolymer latex with a functional group-containing monomer.
- 7. The process-as defined in claim 1, wherein 2-6 g/m.sup.2 of aqueous penetrant solution is applied to the dried coated paper surface.
