වර්ණක රතු 242 has a yellowish red or large red phase, and is excellent in solvent resistance and acid / alkaline resistance. It is mainly used for coloring of plastics such as PVC, PS, ABS, and polyolefins. It is heat-resistant to 300 ° C (1 / 3SD) in HDPE, but it affects dimensional deformation. It is suitable for the coloring of raw pulp of polypropylene and resistance to migration in soft PVC. It has medium tinting strength; it is also recommended for coatings, automotive coatings, anti-glazing paints, and heat-resistant 180 ° C; for high-end printing inks, such as PVC film and metal decorative printing inks, laminated plastic films, etc.

Synthetic principle: 2-chloro-5-trifluoromethylaniline is added to a hydrochloric acid medium, and an aqueous solution of sodium nitrite is added to carry out the diazotization reaction; the diazonium salt is reacted with 2-hydroxy-3-naphthoic acid to produce Mono-azo dyes are reacted with sulfoxide in o-dichlorobenzene to be converted into acid chloride derivatives; and then subjected to a condensation reaction with 2,5-dichloro-1,4-phenylenediamine to produce crude azo condensation products, CI pigment red 242 was prepared by pigmentation.
