A coated paper sheet having a coating layer formed on one or two surfaces of a substrate paper sheet and containing a pigment and a binder, wherein the pigment includes kaolin particles having an average particle size of 0.3 to 1.5 mum and an aspect ratio L/W (L: major axis, W: minor axis of the particles) in the range of 5 to 50; the binder contains (a) a copolymer having a glass transition temperature Tg of 10 to 60° C. and a single phase structure and/or a synthetic polymeric compound having a core-shell composite structure; the coating layer surfaces have a 75 degree specular glossiness of 50% or more; and the air permeability of the coated paper sheet is 7000 seconds or less, is useful as printing sheet especially for gravure printing.
