2-(p-sulphophenyl)amino-1,3,5-triazine derivative and the salt of alkali metal thereof, a process for the preparation and their use as an auxiliary of cationic dye

Abstract

2-(p-sulphophenyl) amino-1,3 5-triazine derivatives [1] and their alkali salts, wherein R1, represents Cl, F; R2 is α- or β-naphthylamino, or α- or β-naphthoxy, and the method for preparing the compound are provided. The compound can be used as a cationic dye auxiliary agent in dyeing animal protein fibers (such as wool, cony hair, camel hair and natural silk) and their textile fabric as well as blended yarn or fabric containing the animal protein fiber.
