Abstract: <P>PROBLEM TO BE SOLVED: To enhance photofixation efficiency in a thermal color developing layer to shorten a fixing time.  <P>SOLUTION: In this thermal recording paper, a thermal color developing layer 12 and a protective layer 13 are provided on a support 11. The thermal recording layer 12 includes a yellow thermal color developing layer 21, a magenta thermal color developing layer 22, and a cyan color developing layer 23 in that order from the upper side A. Regarding the visible light, the thermal color developing layers 21 to 23 have an equivalent refractive index. For yellow fixation light, the refractive index of the yellow thermal color developing layer 21 is made equivalent to that of the magenta thermal color developing layer 22. For magenta fixation light, the yellow thermal color developing layer 21 has a higher refractive index than the magenta thermal color developing layer 22. Further, in the thermal color developing layers 21 to 23, for fixation light of each of the layers, the refractive index within the microcapsule is made smaller than the refractive index of the wall or the exterior of the microcapsule. A color thermal recording paper 10 having the above construction is excellent in transparency of a non-color developing part and is excellent in light fixation efficiency. Therefore, the fixation time is shortened, and an increase in recording speed can be realized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
