An ink jet recording sheet having an enhanced ink-absorbing property and bright color image-forming property and an excellent surface hardness has a specific coating layer formed on a surface of a substrate sheet, which comprises a pigment and a resinous binder composed of a cationic copolymer prepared by copolymerizing (a) 99.95 molar % or less of a principal copolymerization component comprising at least one fatty acid vinyl ester comonomer with (b) 0.05 to 0.4 molar % of a cationic copolymerization component comprising at least one cationic comonomer having an ethylenically unsaturated hydrocarbon radical and a cationic radical selected from tertiary amino radicals and quaternary ammonium radicals and, optionally, a member selected from (c) an additional copolymerization component comprising at least one polymerizable non-ionic comonomer different from the fatty acid vinyl ester and (d) a graft copolymerization component comprising polyvinyl alcohol.

Ink jet recording sheet and process for producing same

A method of manufacturing containers covered tightly with a protective sheet with a porous resin film layer or rubber film layer in-between. By the method of this invention, a resin solution or rubber solution is foamed mechanically in advance and the foamed layer made by the foamed resin film or the foamed rubber film then is covered with a heat shrinkable sheet which is heat shrunk tightly to the containers. The foamed layer does not shrink during the heating. Accordingly, the surface of the heat shrinkable sheet is free from waviness due to gas foaming of the covered layer during heat shrinking which has been the case with conventional methods. The method, therefore, does not affect the appearance or printing performance of the surface of the heat shrinkable sheet.
