  • Method for manufacturing polarizing plate
    Patent number: 11975500
    Abstract: Provided is a method for manufacturing a polarizing plate, comprising a step of irradiating an optical laminate with ultraviolet rays having an emission wavelength band of 380 nm to 410 nm. The optical laminate sequentially comprises a first base film, a first adhesive layer, a linear polarizer, a second adhesive layer, a second base film and a reverse dispersion liquid crystal layer. The first adhesive layer and the second adhesive layer each comprise a photosensitizer for initiating a curing reaction in a wavelength band of 350 nm to 410 nm, and the ultraviolet rays are irradiated on the first base film side of the optical laminate.

  • Method for the reduction of acrylamide formation
    Publication number: 20060240174
    Abstract: The present invention relates to a method for the reduction of acrylamide formation, in which a nucleophilic a-amino group (—NH2) is protonated and converted into a non-nucleophilic amine (—NH3+). The inventive method has the effect of allowing the formation of acrylamide to be highly reduced by simple treatment with a pH-lowering agent. Particularly, when applied to foods or foods ingredients, the inventive method has the effect of allowing the formation of acrylamide to be highly reduced without affecting the flavor and color of the foods or foods ingredients.
