ABSTRACT:
An aqueous ink recording sheet is described which is prepared by coating on the surface of a substrate sheet a resin composition containing as the chief ingredient a mixture comprising (A) 10 to 90 wt % of photo polymerizable, double bonded anionic synthetic resin, and (B) 90 to 0 wt % of partially or completely saponified polyvinyl alcohol, or partially or completely saponified polymer resin composed of 20 to 100 wt % of vinyl acetate and 80 to 0 wt % of other polymerizable monomer or derivatives thereof, and/or (C) 90 to 0 wt % of homopolymer resin of N-vinylpyrrolidone or copolymer resin of other polymerizable monomer therewith, with the weight ratio of (A)/[(B)+(C)] being 90/10 to 10/90, drying the coated resin composition, and then curing the resin composition by the irradiation with actinic rays so as to form a resin coating layer on the substrate.
The aqueous ink recording sheet of the present invention is not only capable of recording distinctly and sharply the multicolor full color copy that is an advantageous point in ink jet process but also excellent in both the adsorbency and the dryness against the ink.
