FORMING METHOD OF COATING FILM TO POROUS SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a forming method of a coating film to the surface of a porous substrate having no problem from an aspect of production such as strike-through or the stop of production and capable of obtaining the coating film such as desired printing or a protective film. SOLUTION: The forming method of the coating film to the surface of the porous substrate 11 is composed of a process (1) for forming a non-porous layer 13 to one side of the porous substrate 11, a process (2) for forming the coating film 15 to the other side of the porous substrate 11 from a liquid composition by a coating method and/or a printing method and a process (3) for peeling and removing the non-porous layer 13 after the coating film 15 is formed. The forming method of the non-porous layer 13 is preferably a dry lamination method using an adhesive in an amount of 0.5-10 g/m2or an extrusion coating method using no anchor coat.
