ABSTRACT:
A heat-sensitive color transfer recording media comprising a continuous foundation and a multiplicity of coated areas of heat-sensitive transfer inks applied onto the foundation; the multiplicity of the coated areas being disposed on the continuous foundation side by side so as to traverse the continuous foundation; the multiplicity of the coated areas being arranged sequentially in the longitudinal direction of the continuous foundation in a repeating unit which comprises a plurality of different color coated areas; each of the different color coated areas included in the repeating unit having a length in the longitudinal direction of the continuous foundation substantially equal to the length or width of a copy sheet; each of the heat sensitive transfer ink layers of the coated areas being a transparent ink layer comprising a transparent coloring agent and a transparent hot-melt vehicle; and said plurality of the different color heat-sensitive transfer ink layers of the coated areas of the recording media being transferred onto the copy sheet so that different color ink images are superimposed on the copy sheet to give a color image. By employing the recording media, a color copy having a clear color image with a high resolution can be obtained at low cost.
