ABSTRACT:
A transfer recording medium comprises a substrate and a transfer recording layer disposed thereon capable of changing its transfer characteristic when provided with light energy and heat energy. The transfer recording layer comprises image forming elements which are solid at room temperature and comprise at least a colorant and a functional component sensitive to the provision of light energy and heat energy. Since the image forming elements have a mode particle size of 5-25 .mu.m and comprise 50% by number or more of those having a particle size of .+-.4 .mu.m or less from the mode particle size, the transfer recording medium affords a clear transferred image with high resolution at a high transfer rate when provided with light and heat energies, at least one of which is applied imagewise.
