Title:
光学積層体および光学積層体の製造方法
Document Type and Number:
Japanese Patent JP6774556
Kind Code:
B2
Abstract:
The present invention provides an optical laminate that has excellent adhesion between a resin substrate and a polarizing film, wherein the difference between the peeling force when the resin substrate is peeled from the optical laminate and the peeling force when the polarizing film is peeled from the optical laminate is reduced. The optical laminate according to the present invention has a resin substrate and a polarizing film that is disposed on one side of the resin substrate, wherein P1 (N/15 mm), which represents the peeling force when the resin substrate is peeled from the optical laminate at an angle of 90º, and P2 (N/15 mm), which represents the peeling force when the polarizing film is peeled from the optical laminate at an angle of 90º, satisfy formula (1). Formula (1): 0.5 < P1/P2 < 5
