| titleOfInvention | Polarizing film having ultraviolet absorbing ability and its production |
| abstract | The present invention relates to a method for imparting ultraviolet absorbing performance to a polarizing film based on a polyvinyl alcohol film and a polarizing film having ultraviolet absorbing performance produced by the method. The present invention dissolves a composition consisting of 95 to 80% boric acid and 5 to 20% boric acid in water to make 100 parts of an aqueous solution of 0.05 to 1.5% of boron, and an organic ultraviolet absorber 2,2 ', 4,4'ted La hydroxy benzophenone was added to 0.05 to 0.5 parts by weight to dissolve the polyvinyl alcohol film before the fixing process, which was prepared by mixing the three-component aqueous solution of the organic ultraviolet absorber, boric acid and borax, and stretching and dyeing the mixed aqueous solution according to a known method. High durability, high polarization dye-based polarizing film having ultraviolet absorbing ability produced by immersing 30 seconds to 5 minutes at a temperature of -60 ° C. and pH 4.5 to 7.2 at the same time in the same bath at the same time. To provide. |
