PURPOSE:To record full-color thermally transfered images with favorable quality on a transparent film, by selecting the refractive indices of light-transmitting particles and a light-transmitting adhesive constituting a rugged surface layer so that they are matched with each other. CONSTITUTION:To the surface 1a of transparent light-transmitting sheet 1 of polyethylene terephthalate, polypropylene or the like, the light-transmitting particles 2 such as particles of a glass are dispersely adhered by a light- transmitting adhesive 3 to provide the rugged surface layer 5. The particles 2 and the adhesive 3 are light-transmitting and the refractive indices thereof a selected to be approximately equal, so that reflection of light at the interface between the particles 2 and the adhesive 3 is prevented from occurring. Therefore, light transmittance is enhanced, reverse transfer is prevented from occurring by the rugged surface, and the adhesive 3 shows favorable ink receptivity. Accordingly, it is possible to perform thermal transfer recording of full-color images to produce a light-transmitting color image film such as a slide film and an OHP film. |
