<P>PROBLEM TO BE SOLVED: To provide a water resistant laminated sheet which improves the ink-setting properties when offset printing is performed using general-purpose ink, and has excellent wear resistance. <P>SOLUTION: The water resistant laminated sheet includes, on a sheet coated with a thermoplastic resin: a coating layer composed of a composition of inorganic ultrafine particles and a copolymer; or a coating layer containing a composite body of inorganic particles and organic particles. In the water resistant laminated sheet, the coating layer has nanopits, the diameter of the nanopits is 20 to 300 nm, and also, the occupancy ratio of the nanopits in the surface of the coating layer is 2 to 40%. It is preferable that: the inorganic ultrafine particles in the coating layer are composed of colloidal silica, the copolymer is composed of a styrene-acrylic copolymer or an acrylic copolymer; and the ratio of solid contents between the inorganic ultrafine particles and the copolymer is 100:10 to 100:100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
