Methine dyestuffs

NBP reacts with epoxides according to I to yield methine dyestuffs [14] and with alkylating agents (R-X, X = e.g. halogen) according to II to yield colored pigments [15]. [Pg.360]

The largest usage is in polyester and many dyestuff companies have disperse dye ranges for this purpose, some of which are also applied to polyamide fibres. The main colours are in the yellow, orange, red, pink and violet areas with coumarins, methines and perylene dominating the structural classes. [Pg.183]
