Title:
PRINTING SHEET
Document Type and Number:
WIPO Patent Application WO/2019/116478
Kind Code:
A1
Abstract:
[Problem] To provide a printing sheet which is able to be smoothly separated from an adherend, while having high strength. [Solution] According to the present invention, a printing sheet 10 is configured of: a base material film 12; a toner fixation layer 18 which is formed on one main surface of the base material film 12; a planarization layer 20 which is formed on the other main surface of the base material film 12; an adhesive layer 22 which is formed on the surface of the planarization layer 20; and a release film 24 which is bonded to the surface of the adhesive layer 22. The base material film 12 has a multilayer structure that is composed of a white foamed PET film layer 14 on the toner fixation layer 18 side and a transparent non-foamed PET film layer 16 on the adhesive layer 22 side; and the strength of the printing sheet 10 is improved by the combined use of the non-foamed PET film. The planarization layer 20 is composed of a colored ink layer (for example, a white ink layer), and increases the joint area between the base material film 12 and the adhesive layer 20, thereby enabling smooth separation from an adherend.
