Zusammenfassung:	PURPOSE: To prepare cast-coated paper having excellent aqueous gravure printabllity, especially excellent ink drying properties and ink colorability as paper for gravure printing. CONSTITUTION: In cast-coated paper provided with a coated layer comprising pigment and a water-soluble and/or water-dispersible adhesive as main components, the cast-coated paper is provided with a coated layer which comprises a pigment having a ratio of 10-80 pts.wt. of the pigment having >=1.20ml/g relative sedimentation volume in 100 pts.wt. of the whole pigment as the pigment, at least 1-30 pts.wt. of an aqueous urethane resin based on 100 pts.wt. of the pigment as the water-soluble and/or water-dispersible adhesive and 1-25 pts.wt. of a water-soluble polymer based on 100 pts.wt. of the pigment and subjected to cast finishing to give the objective cast-coated paper for aqueous gravure printability.
