A polarizing structure comprising a polarizing film, a protective film provided on at least one face of the polarizing film with an adhesive layer which is a glyoxal-based adhesive or a water based polymer adhesive such as a PVOH-based adhesive layer, and wherein at least one face of said protective film oriented towards said polarizing film further comprises an adhesion primer structure. The adhesive avoids delamination of the polarizing structure, which withstands edging processing conditions, and which also show excellent dry peel force. Other aspects of the invention relates to a method for manufacturing such a polarizing structure, and a polarized ophthalmic lens comprising such polarizing structure.

A manufacturing method which includes: (1) an alkali cellulose reaction step wherein a mixed solvent having a mixing ratio (a mass ratio) of an alcohol having a carbon number of 3 or less and water of 75:25 to 95:5 is used, and the concentration of the base to the water is 25 to 40 mass %; (2) an etherification reaction step wherein a reaction is carried out under an excess base of 0.2 to 0.5 moles per unit of an anhydroglucose of the cellulose; (3) a neutralization step wherein acid is added to adjust the pH of the reaction mixture to 6.0 to 8.0; and (4) a heating step wherein the mixed solvent is removed, and a base is added to adjust the pH of the reaction mixture to 8.0 to 9.0, and then a heat treatment is performed at 40 to 70 C. for 30 to 120 minutes.

An electrically conductive paste contains: metal nanoparticles which are protected by an organic compound containing an amino group and have an average particle diameter of 30 nm to 400 nm; metal particles which are protected by a higher fatty acid and have an average particle diameter of 1 m to 5 m; an organic solvent; and a resin component consisting of a cellulose derivative.
