MANUFACTURING METHOD FOR POLARIZING MEMBER

摘要

PROBLEM TO BE SOLVED: To develop a manufacturing method for a polarizing member by which a overlapping layer of a cross-linked resin excellent in adhesion strength to a polarizing plate can be attached. SOLUTION: In forming a cross-linked resin layer superposed on at least one side of a polarizing plate in two or more layers, a crosslinking processing is performed so that an upper layer is recoated on a lower layer whose crosslinking reaction is controlled to 10-50% and the rate of crosslinking reaction of the lower layer becomes 80% or more with the upper layer. The lower layer and the upper layer form a cross-linked structure mutually at the boundary face.
