Title:
LAMINATED ORIENTED FILM, BASE MATERIAL FOR DECORATIVE SHEET, DECORATIVE SHEET AND DECORATIVE PLATE
Document Type and Number:
Japanese Patent JP2023158003
Kind Code:
A
Abstract:
To provide a laminated oriented film which enhances an elastic modulus of a base material for a decorative sheet while maintaining peeling strength (interlayer adhesive force) that can be evaluated by peeling test force with a laminate including a base material for a decorative sheet and a transparent resin layer provided on the upper layer of a printing layer, and thereby improves mechanical strength while being thin, a base material for a decorative sheet, a decorative sheet and a decorative plate.SOLUTION: A base material 6 is a uniaxially or biaxially laminated oriented film which contains a resin material mainly containing polypropylene, wherein the main component of the resin material has a plurality of layers (number n of layers≥2, n is an integer) composed of a polypropylene-based resin. When the uppermost layer positioned on the outermost surface out of the plurality of layers is defined as a surface layer 6-1, layers other than the surface layer 6-1 out of the plurality of layers are defined as core layers 6-2 to 6-(n-1), Martens hardness of the surface layer 6-1 is 20 N/mm2 or more and less than 120 N/mm2, and a peak intensity ratio by Raman spectroscopy is 1.0 or more and less than 6.0.SELECTED DRAWING: Figure 1
