Polarizing element i.e. glass-free polarizing lens, manufacturing method, involves lapping time between manufacturing and application of solution of adhesive agent on basis of change of molecular weight of agent determined in solution

摘要

The method involves forming a polarization film by an application of solution containing a dichroic dye e.g. azoic dye, on an orientation layer. Solution of hydro silicon adhesive agent containing epoxy groups is produced by addition of adhesive agent to aqueous solvent. Time between manufacturing and application of the solution of the adhesive agent containing the epoxy groups is lapped on a basis of a change of molecular weight of the adhesive agent determined in the solution of the adhesive agent. The orientation layer made of silicon oxide.
