摘要： Proposed are novel ink-jet recording sheet having high water resistance, excellent transparency of the ink-receptive layer, ink absorptivity and color developability as well as the advantages of absence of surface tackiness and blocking and a liquid coating composition for forming the ink-receptive coating layer of the recording sheet. The liquid coating composition comprises, as a uniform blend in an aqueous medium: (A) an acetoacetylated polyvinyl alcohol; (B) a polyvinylpyrrolidone resin; and (C) an acidic aqueous dispersion of a colloidal silica, each in a specified weight proportion, in a limited weight proportion.

摘要： Provided by the invention is a recording film suitable for recording by using an ink-jet printer capable of giving very sharp printed images and having advantages of rapid drying of the water-base printing ink thereon and little re-transfer of the printed images directly after printing onto the surface coming into contact with the printed surface of the recording film. The recording film is a layered sheet material comprising (A) a base film of a plastic resin; (B) an ink-receptive layer formed from a mixture of a polyvinyl alcohol and a polyvinyl pyrrolidone; and (C) an overcoating layer on the ink-receptive layer. The overcoating layer is formed from a mixture of a water-insoluble polyvinyl acetal resin, fine particles of an acrylic resin and a polyvinyl pyrrolidone.
