Title:

METHOD FOR PRODUCING PROTECTIVE FILM-ATTACHED LAMINATE, AND PROTECTIVE FILM-ATTACHED LAMINATE

Document Type and Number:

WIPO Patent Application WO/2019/066079

Kind Code:

A1

Abstract:

According to an aspect of the present invention, a method for producing a protective film-attached laminate 10 is provided, the method comprising: a step for preparing a laminate 20 having a first substrate 21 and a first resin layer 22 which is provided on a first face 21A that is one face of the first substrate 21, the first resin layer 22 having an indentation hardness of at least 100 MPa in a cross section along the film thickness direction D; a step in which a second resin layer composition containing an ionizing radiation-polymerizable compound is applied onto a first face 31A, which is one face of a second substrate 31, and dried to form a coating film 35; a step for bringing the laminate 20 into contact with a coating film 34 such that the first resin layer 22 contacts the coating film 35; and a step for irradiating the coating film 35 with ionizing radiation in a state in which the laminate 20 contacts the coating film 35, and thereby curing the coating film 35 and forming a peelable protective film 30 having a second substrate 31 and a third resin layer 32 which is disposed closer to the first resin layer 22 than the second substrate 31, is composed of a cured product of the coating film 35, and has an indentation hardness of at least 100 MPa in a cross section along the film thickness direction D.
