Document Type and Number:
WIPO Patent Application WO/2022/198725
Kind Code:
A1
Abstract:
The present invention relates to the field of organic pigments, and in particular, to a perylene pigment and a preparation method therefor. The perylene pigment of the present invention has a general formula below, wherein Y is H or Cl, and X is C=O, C=S, or C=NH, Bx, Cr'R". According to the perylene pigment, by introducing a hydrogen bond, a new chromophoric group, and a combination of an electron withdrawing group and an electron donating group, not only a blue compound is obtained, but also the stability and weather resistance of color are improved, such that good flocculation resistance is achieved, and the perylene pigment can be used for thermal dye sublimation, is applicable indoors and outdoors, and has a wide application prospect. The preparation method of the present invention is simple in process, easy to prepare and high in yield, and satisfies industrial production and manufacturing requirements.
