Document Type and Number:
Japanese Patent JP6578765
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas barrier laminated body exhibiting excellent optical properties and gas barrier over a long period even in a severe environment.SOLUTION: Provided is a gas barrier laminated body 10 including: a vapor-deposited layer 12 laminated on at least one side of a resin base material 11; and an overcoat layer 13 laminated on the vapor-deposited layer 12, in which (a) water vapor permeability under the measurement conditions of 40°C and relative moisture of 90% is 0.1 g/(mday) or lower and (b), when the gas barrier laminated body is subjected to a high moisture test of performing preservation for 500 hr under the conditions where temperature is 60°C and relative humidity is 90%, the maximum change rate (ΔT%) of the light permeability in the visible region wavelength of 400 to 700 nm of the gas barrier laminated body before and after the high moisture test is below 3%.SELECTED DRAWING: Figure 1
