Abstract

A printing sheet is formed of a base material film, a toner fixing layer formed on one principal surface of the base material film, a planarization layer formed on the other principal surface of the base material film, an adhesive layer formed on the surface of the planarization layer, and a peeling film stuck on the surface of the adhesive layer. The base material film has a laminated structure composed of a white foamed PET film layer on the toner fixing layer side and a transparent non-foamed PET film layer on the adhesive layer side, and the strength of the printing sheet is improved by the combined use of the non-foamed PET film. The planarization layer is formed of a colored ink layer, e.g. white ink layer, and increases the bonding area of the adhesive layer with the base material film side, thereby achieving smooth peeling from an adherend.

Dependent claims

A printing sheet comprising:

a base material film;
a toner fixing layer which is formed on one principal surface of the base material film and is printable;
an adhesive layer which is formed at a side of the other principal surface of the base material film;
a planarization layer provided between the base material film and the adhesive layer;
and
a peeling film which is stuck on a surface of the adhesive layer,
wherein the base material film includes a foamed polyethylene terephthalate resin film at a side of the toner fixing layer and a transparent non-foamed polyethylene terephthalate resin film at a side of the adhesive layer to form a laminated structure, and the adhesive layer is formed of an ethylene-vinyl acetate copolymer resin.
