Description

technical field [0001] The invention relates to a dye, in particular to a solvent-type dye composition and a preparation method thereof. [0002] Background technique [0003] Perylene pigments are a class of high performance (HPP) organic colorants. As early as 1913, perylene-based products (perylene red) had been developed, but before 1950, it was mainly used as vat dyes, such as 90# bright red, due to the market demand for high-grade organic pigments and breakthroughs in the technical field , In 1951, it was synthesized into several varieties of pigments, which are widely used in plastics, synthetic fibers, coatings and other industries. At present, the consumption of perylene pigments in the world market is about 2300t / year, and the consumption of automobile paint is the largest, which is about 1800-1900t / year. [0004] The reason why perylene pigments have excellent application properties mainly depends on their special molecular structure. Its molecular structure i...
