Claims
- 1. A heat transfer system comprising a heat transfer sheet and an system used in combination therewith, said image-receiving sheet comprising:
- a substrate sheet; and
- a dye-receiving layer provided on at least one surface of said substrate sheet, said dye-receiving layer comprising a dyeable resin comprising at least vinyl chloride/vinyl acetate copolymer and an ultraviolet-absorbing agent selected from the group consisting of benzotriazole compounds, cyanoacrylate compounds, salicylate compounds and oxalic anilide compounds, said ultraviolet-absorbing agent having a melting point of from 60.degree. C. to 140.degree. C.
- 2. The heat transfer system according to claim 1, wherein said ultraviolet-absorbing agent has a sensitizing effect.
- 3. The heat transfer system according to claim 1, which is capable of producing an image with a relative optical reflection density of more than 1.00.
- 4. The heat transfer system according to claim 1, wherein said ultraviolet-absorbing agent has a heat of fusion (.DELTA.H) of from 10 mJ/mg to 300 mJ/mg.
- 5. The heat transfer system according to claim 1, wherein said ultraviolet-absorbing agent has a molecular weight of from 150 to 400.
- 6. A heat transfer system comprising a heat transfer sheet and an system used in combination therewith, said system comprising:
- a substrate sheet; and
- a dye-receiving layer comprising a dyeable resin comprising at least vinyl chloride/vinyl acetate copolymer and an ultraviolet-absorbing agent having a melting point of from 50.degree. C. to 150.degree. C., said ultraviolet-absorbing agent consisting of benzophenone compounds represented by the following formula: ##STR11## wherein R.sub.1 is a hydrogen atom, a hydroxyl group or an alkoxyl group having 1 to 21 carbon atoms,
- R.sub.2 is a hydroxyl group, an alkoxyl group having 1 to 21 carbon atoms, a hydroxyalkoxyl group having 1 to 21 carbon atoms or a phenylalkoxyl group having 1 to 21 carbon atoms, and
- R.sub.3 is a hydrogen atom, a sulfonic acid group or an alkoxyl group having 1 to 21 carbon atoms.
- 7. The heat transfer system according to claim 6, wherein said benzophenone compound is selected from the group consisting of the following compounds (i) , (ii) and (iii): ##STR12##
