Title:
OPTICAL LAMINATE
Document Type and Number:
Japanese Patent JP2018141962
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical laminate that can effectively reduce transition of a dichroic dye contained in a polarizing film to a conductive layer to prevent deterioration of the conductive layer.SOLUTION: An optical laminate has a first cured material layer that is formed of a cured material of a curable composition containing a polymerizable compound, an adhesive layer, and a conductive layer laminated in this order on one face of a polarizing film that contains a dichroic dye in a polyvinyl alcohol resin, where the first cured material layer has a rate of increase in absorbance represented by the following formula (1) of 30% or less. (1) the rate of increase in absorbance (%)=(after immersion Abs(360nm)-before immersion Abs(360nm))/before immersion Abs(360nm)×100.SELECTED DRAWING: None
