Abstract

4097. Ransford, R. B., [Cassella & Co., L.]. Feb. 19. Dyes, artificial. - Colouring-matters dyeing cotton directly greenish-yellow shades exceptionally fast to washing are produced by heating a mixture of dehydrothiotoluidine, or derivatives thereof containing a higher proportion of sulphur, and benzidine, or thiobenzidine with sulphur, and transforming the products so obtained into soluble colouring-matters by treating with concentrated solutions of caustic alkalies or alkali sulphides.
