HEAT-SENSITIVE TRANSFER RECORDING MEDIUM

PROBLEM TO BE SOLVED: To provide a printing image which has a favorable transfer property and a high security by a method wherein the major components of a protective layer are made of an acrylic resin and a diallylphthalate resin. SOLUTION: The major components of the protective layer of a heat-sensitive transfer recording medium, are made of an acrylic resin and a diallylphthalate resin. By jointly applying the acrylic resin and the diallylphthalate resin in such a manner, a printing image which is excellent in transfer property, especially 1 dot reproductivity, and in addition, is excellent in abrasion resistance and solvent resistance, etc., and has a high security can be obtained. It is preferable to make the mixing ratio (weight ratio, the same way hereinafter) of the acrylic resin and diallylphthalate resin is made 95:5-70:30. When the mixing ratio of the diallylphthalate resin is less than 95/5, the transfer property, especially the 1 dot reproductivity decreases, and there is an inclination that the visibility of the image is inferior. In the meantime, when the mixing ratio of the diallylphthalate resin is more than 70/30, there is an inclination that the security such as abration resistance and solvent resistance is inferior.
