Title:
LAMINATE FOR IMAGE DISPLAY DEVICE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/049687
Kind Code:
A1
Abstract:
The laminate for an image display device of the present invention at least comprises: an adhesive layer formed of an adhesive composition comprising an adhesive polymer (A), a conductive polymer (B) comprising a conjugated polymer and a polyanion, and a crosslinking agent (C), an image display element located on one of two surfaces of the adhesive layer, and a polarizing film located on the other surface of the adhesive layer, wherein with respect to a test material comprising the adhesive layer having the polarizing film on one surface and a protective material, which has a release layer and which comprises polyethylene terephthalate (PET), on the other surface of the adhesive layer, with the adhesive layer and the release layer being located so as to be adjacent to each other, when the protective material is peeled off from the test material in an environment of a temperature of 23C and a relative humidity of 50%, a surface resistivity of the adhesive layer is 1 x 1012Ω/□ or less, a haze value of the test material from which the protective material has been peeled off is 2% or less, and the following formula (1) is satisfied. y/x < 10 ・・・ (1) (wherein x represents a surface resistivity of the adhesive layer when the protective material is peeled off from the test material in an environment of a temperature of 23°C and a relative humidity of 50%, and y represents a surface resistivity of the adhesive layer when the protective material is peeled off from the test material in an environment of a temperature of 23°C and a relative humidity of 50%, provided that the test material has been maintained in an environment of a temperature of 60°C and a relative humidity of 90% for 500 hours and dried at 80°C for 1 hour.)
