Abstract

The invention relates to application of a bistable photochromic material in ink, bistable photochromic ink and a preparation method thereof. The bistable photochromic ink consists of the following components in parts by weight: 1-10 parts of the bistable photochromic material, 1-25 parts of extender pigment, 20-55 parts of connection material and 3-45 parts of additive. According to the invention, the problem that the photochromic state of the existing ink disappears along with the light source is solved, and the colorless bistable photochromic ink with a good anti-fake effect is provided.

Description

technical field [0001] The invention relates to the application of a bistable photochromic material in ink, a bistable photochromic ink and a preparation method thereof. Background technique [0002] Existing photochromic inks undergo a discoloration reaction after absorbing a certain wavelength of light energy, the light disappears, and the color returns to the initial state; but there is no photochromic reaction and a stable discoloration state, and another ink with a certain energy intensity must be absorbed. The photochromic ink can only be restored to its original state after a certain amount of light energy, and the absorption wavelength is in the visible light region. Contents of the invention [0003] The purpose of the present invention is to provide a colorless bistable photochromic ink which is applicable to various printing methods and has good anti-counterfeiting effect, and solves the problem that the photochromic state of the ink disappears with the light so...
