Thermally stable anthrapyridone compositions

Public has a formula (I) of anthracene pyridine ketone combination property, which "a," and "b" respectively selected since has about 10 to about 20 a ring carbon Atomic of replaced or is not replaced of ring ketone group; "a," for 0-4 of integer, R1-R4 for price replaced base; Dang "a," for 0 o'clock, R1 selected since hydrogen, and alkyl, and Jones Lang LaSalle amine base and contains sulfonic base of group; R2-R4 for selected since hydroxy, and fat hydrocarbon base, and aryl, and hybrid ring base, and halogen Atomic, and cyanide base, and with Carbonyl of group, and amino and with sulfonic base of Group of replaced base. Anthracene described one used as a heat-stable colorant, preparation for coloring of polymer resins and components you need.
