Title:
LAMINATE, COMPOSITE POLARIZING PLATE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/176719
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a laminate in which the rate of change of resistance of a transparent conductive layer is small even in a high-temperature and high-humidity environment. In addition, another purpose of the present invention is to provide a composite polarizing plate and an image display device employing said laminate.
The present invention provides a laminate characterized in that a transparent conductive layer and a pressure-sensitive adhesive layer having a moisture permeability of 100 g/(m2·day) or less, at a temperature of 40ºC and a relative humidity of 92%R.H., are laminated in contact with each other. It is preferable that the pressure-sensitive adhesive layer be a rubber-based adhesive or a polyolefin-based adhesive.
