Abstract

The invention discloses a color adhesion agent and its manufacturing process and a polaroid with the application of the color adhesion agent. The color adhesion agent comprises the following components: by weight, 1-5% of an adhesion agent raw material, 93-98.75% of pure water, 0.25-1.5% of a dye, and 0.5% of a color fixing agent. The adhesion agent which can be used to adjust a plurality of colors can be used to bond a cellulose triacetate (TAC layer) and a PVA layer, and after drying and curing, the color polaroid with high degree of polarization and high transmitance is immediately obtained. The polarization degree of the iodine Polaroid reaches more than 99%, transmitance reaches more than 40%, and polaroids of different colors can be obtained. Thus, usage requirements are met.

Description

technical field [0001] The invention relates to an adhesive, in particular to a colored adhesive, a manufacturing process and a polarizer using the colored adhesive. Background technique [0002] The current polarizers can be divided into iodine-based polarizers and dye-based polarizers according to the manufacturing method. The adhesives used in these two types of polarizers are transparent liquids. Iodine-based polarizer refers to a polarizer that uses other additives such as iodine and potassium iodide as a dichroic medium, which can make the PVA film produce polar polarization characteristics. The polarization degree of the polarizer made by this manufacturing method reaches 99.9%. The pass rate reached 42%. However, this manufacturing method can only produce gray polarizers. [0003] Dye-based polarizers refer to polarizers dyed with dichroic dyes. This manufacturing method can produce polarizers of various colors. However, the degree of polarization of polarizers pro...
