ABSTRACT:
This temporarily sticking material includes a base material opaque at least partly, an inter-layer peel ply formed on the principal surface of the base material, a synthetic resin layer transparent at least partly formed on the principal surface of the inter-layer peel ply and an adhesive layer formed on the principal surface of the synthetic resin layer being transparent in the part corresponding to the transparent part of the synethic resin layer. The synthetic resin layer of the temporarily sticking material is stuck on a material to be sticked with the adhesive layer. The base material of the temporarily sticking material can be easily peeled off the synthetic resin layer in the part where the inter-layer peel ply is formed. And the secret information shown on the principal surface of the material to be sticked is visible through the synthetic resin layer when the base material is peeled off the synthetic resin layer.
