Abstract
A heat transfer image-receiving sheet including (i) a substrate sheet, and (ii) a dye-receiving layer including an ultraviolet-absorbing agent having a melting point of from 50.degree. C. to 150.degree. C. and provided on at least one surface of the substrate sheet.
Claims7
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.
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.
