Title:
LAMINATED FILM
Document Type and Number:
Japanese Patent JP2018154004
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated film excellent in adhesibility between a substrate layer and a hard coat layer, and excellent in adhesiveness between layers under high temperature and high humidity.SOLUTION: The laminated film is provided which has a substrate layer (layer A) containing a polyester resin as a main component, and a resin layer (layer B) on at least one surface adjacent to the layer A, and in which a carboxyl terminal group amount of the polyester resin of the layer A is 20 eq/ton or more and 50 eq/ton or less. The laminated film satisfies expression 1: 230≤Tmeta+0.05T, in expression 1, Tmeta represents a minute endothermic peak temperature (°C) of the laminated film obtained by differential scanning calorimetry (DSC), and T represents a thickness (μm) of the laminated film.SELECTED DRAWING: None
