Abstract
A method for producing a laminate, the method comprising at least a pretreatment step of pretreating a surface of a substrate made of a plastic film by reactive ion etching so that the maximum displacement of the substrate surface measured by local thermal analysis is 300 nm or more, and a lamination step of laminating a thermoplastic resin layer made of a material different from that of the substrate on the pretreated surface of the substrate; wherein the plastic film is a polyethylene terephthalate film.
Claims8
A method for producing a laminate, comprising the steps of:
- a pretreatment step of pretreating a surface of a substrate made of a plastic film by reactive
- ion etching so that a maximum displacement of the surface of the substrate measured by local thermal analysis is 300 nm or more, and
- a lamination step of laminating a thermoplastic resin layer made of a material different from that of the substrate on the pretreated surface of the substrate;
- wherein the plastic film is a polyethylene terephthalate film.
A laminate comprising:
- a substrate made of a plastic film;
- and,
- a thermoplastic resin layer on the substrate;
- wherein
- the thermoplastic resin layer is made of a material different from a material constituting the substrate, and
- when the substrate and the thermoplastic resin layer are peeled in a wet state, a difference C between a carbon concentration of a peeled surface of the substrate and a carbon concentration of a peeled surface of the thermoplastic resin layer after peeling satisfies the following formula (A) in measurement by X-ray photoelectron spectroscopy (XPS):
- 0≤|C|≤10 (atomic %) Formula (A)
A laminate, comprising:
- a substrate made of a plastic film;
- and,
- a thermoplastic resin layer on the substrate;
- wherein
- the plastic film is a polyethylene terephthalate film, and
- a maximum displacement of a surface of the substrate on a side facing the thermoplastic resin layer is 300 nm or more, the maximum displacement being measured by local thermal analysis.
