PROBLEM TO BE SOLVED: To improve the transparency of an ink fixing layer by incorporating a crosslinked polyalkylene oxide resin with a specified value and a hydrophilic resin with a specified value. SOLUTION: A crosslinked polyalkylene oxide resin is obtained in such a way that polyalkylene oxide and diol are crosslinked by isocyanate compound. A resin having a melt viscosity of 2,000-200,000 poise under a pressure of 50kg/cm<2> at a temperature of 170 deg.C and a water-absorbing capacity of 10-45g/g is suitable. The adding ratio of polyalkylene oxide resin is 20-95wt.% of the total weight of resin composition. As to polyalkylene oxide resin that composes the resin, polyethylene oxide, polypropylene oxide, etc., can be used. As for hydrophilic resin, vinyl pyrrolidone-vinyl acetate copolymer, polyvinyl butyral resin, etc., can be used. The adding ratio of hydrophilic resin is 80-5wt.%. Thereby, a recording material excellent in transparency and water-resistance can be obtained. |
