<P>PROBLEM TO BE SOLVED: To provide an excellent reversible heat-sensitive recording material which enables the formation or the deletion of a recorded image of a high contrast and a high sensitivity over a plurality of times, prevents the anti-fouling property from changing even after repeatedly performing printing and the deletion, and has a sufficient retouching property. <P>SOLUTION: This revertible heat-sensitive recording material has a reversible heat-sensitive recording layer and an outermost surface layer on a support. In this case, the revertible heat-sensitive recording layer contains a normally colorless or a lightly tinted electron-donative dye precursor, and a revertible color developer which can generate a reversible color tone variation on the dye precursor by the difference of a cooling speed after heating as major components. The outermost surface layer is provided on the top of the reversible heat-sensitive recording layer, and mainly contains an ultraviolet curing type resin. In the revertible heat-sensitive recording material, the outermost surface layer contains an ultraviolet curing resin having a dimethyl siloxane group and a (meth)acrylate group in the same molecule. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
