Abstract
Syntheses of 22 kinds of Celliton Fast Green 3 BS and its homologs, and 2 kinds of bromine derivatives of naphthazarin intermediate have been made and their dyeing properties, especially that of gas fading, have been investigated. The dye-ability of these compounds was better for Tetlon than for acetate but the gas fading was not satisfactory except for bromine derivatives of naphthazarin intermediate. Sublimation tests on Tetlon were generally good.
