PURPOSE:To obtain a stratified structure which usually has such a weak tack that it can be released and re-stuck and which can also reveal a strong tack, by providing a supporting base material with a self-adhesive layer of weak tack on one side and a specified self-adhesive layer of strong tack on the other side thereof. CONSTITUTION:This stratified structure consists of a supporting base material, a self-adhesive layer of weak tack provided on one side of this base material, and a self-adhesive layer of strong tack which is provided on the other side of the base material and can be released therefrom by applying a force greater than the tack of said self-adhesive layer of weak tack. Said self-adhesive layer of a photographic sheet, on which a releasable base material, a self-adhesive layer of weak tack, and a release paper are put one over another. By this technique, and release of a photoprint obtained from a photographic sheet after developing can be realized. |
