LAMINATED SHEET AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laminated sheet enhanced in ink absorptivity and constituted so that the cracking of its coating layer is prevented.

SOLUTION: The laminated sheet is constituted by forming a hydrophilic thermoplastic resin layer, a paper base material layer 1 and a coating layer 1 on a support through a thermoplastic resin layer or without interposing the thermoplastic resin layer. The coating layer and the hydrophilic thermoplastic resin layer become moisture absorbing functional layers of ink and, since the paper base material layer 1 is provided between both layers to restrict the effect accompanied by the absorption and swelling of the hydrophilic thermoplastic resin layer by the paper base material layer 1, the cracking of the coating layer does not occur.
