Abstract
The dye receiving sheet for preparation of a transparency according to the present invention is a sheet to be used in combination with a heat transfer sheet having a dye layer formed thereon and includes (2) a transparent substrate, (3) a transparent receiving layer provided on the transparent substrate for receiving the dye migrating from the heat transfer sheet corresponding to the energy applied from a thermal head and (5) an optically detectable layer provided on at least a part of the heat transferable sheet. By the provision of the optically detectable layer (5), improvement of running performance, operability within a heat-sensitive device as well as image density and sensitivity during printing can be attained, and also a detection mark can be freely added, whereby operability of the dye receiving sheet can be further improved.
