Title:
LAMINATE FILM
Document Type and Number:
Japanese Patent JP2020066175
Kind Code:
A
Abstract:
To provide a laminate film of which a substrate film is soft, and steel wool resistance, flexibility, and roll shape storing stability of a laminated hard coat layer is excellent.SOLUTION: There is provided a laminate film having a substrate film (A), a mixed layer (B) and a hard coat layer (C) in this order directly, the substrate film has penetration strength by a nanoindenter measurement of 1 MPa to 50 MPa, the hard coat layer has penetration strength by the nanoindenter measurement of 20 MPa to 100 MPa, the mixed layer is an area existing between the substrate film and the hard coat layer, and a ratio of intensity a1 of X in the hard coat layer and intensity a2 of X in the area, a2/a1 satisfies 0.1 to 0.9, where a fragment exhibiting maximum intensity of the hard coat layer is X measured by a TOF-SIMS method.SELECTED DRAWING: Figure 1
