US 2003/0157278 A1 · Recording material for back-printing

Abstract

A recording material for back-printing contains (i) a back-printing sheet comprising a transparent substrate, an ink-absorbing layer that is provided on the transparent substrate, and a porous ink-receiving layer that is provided on the ink-absorbing layer and has filler dispersed in a binder resin, and (ii) a back-printing sheet cover film having a cover substrate, and an adhesive layer that has an adhesive resin and is formed on the cover substrate, the refractive index of the filler and the refractive index of the adhesive resin are different to one another. Specifically, the difference between the refractive index of the filler and the refractive index of the adhesive resin is at least 1.0.
