PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material which can be observed by high quality of image on an X-ray film viewer. SOLUTION: In the heat-sensitive recording material with a heat-sensitive recording layer on a transparent substrate, the heat-sensitive material is characterized by chromaticity coordinates by JIS Z 8729 when energy is loaded just before color development is started being in a range of L: 73-85, a*: -4.0-0 and b*: 8-16 and the chromaticity coordinates at a transmission density of 3.0 measured by means of a Macbeth transmission density meter TD904 (a visual filter) being in a range of L: 0.5-1.0, a*: 0-2.0 and b*: -1.0-+1.0. |
