PURPOSE:To obtain an ink ribbon for thermal transfer recording capable of obtaining a high-grade recording image constituting the ultraviolet curable resin composition of a heat-resistant lubricating layer of a specific ultraviolet curable resin and a lubricant being a specific ultraviolet curable silicon resin and prescribing the additional amount of the lubricant. CONSTITUTION:A heat-resistant lubricating layer is composed of a heat-resistant lubricating layer composition prepared by adding a photopolymerization initiator and a diluent to an ultraviolet curable resin composition. The ultraviolet curable resin composition is constituted of an ultraviolet curable resin based on polyfunctional acrylate and an ultraviolet curable silicone resin being a lubricant. As polyfunctional acrylate, acrylate represented by formula I is used. As the ultraviolet curable silicone resin being the lubricant, one having an acryloyl group or a methacryloyl group as a functional group is used. The addition amount of the lubricant is set to about 0.1-10 pts.wt. per 100 pts.wt. of the ultraviolet curable resin. By this addition amount, sufficient running properties are kept and head contamination and film irregularity can be prevented. When the ultraviolet curable silicone resin having the acryloyl or methacryloyl group as the functional group is used as the lubricant, the heat-resistant lubricating layer is further enhanced in heat resistance and can prevent thermal fusion. |
