Abstract

1,203,324. Dyeing with salts of sulphuric acid esters of leuco-vat dyes. SANDOZ Ltd. 4 Jan., 1968 [5 Jan., 1967], No. 560/68. Heading D1B. Fibrous materials e.g. cotton, linen, silk, regenerated cellulose, polyamides, polyesters and polyacrylonitriles, especially polyester/cotton mixtures are padded or printed with compositions which contain a salt of a sulphuric acid ester of a leuco-vat dye and an alkali metal nitrite, e.g. sodium nitrite, no acids or compounds yielding acid being present, the materials are then dried and the dye fixed by a heat treatment preferably for 5 secs. to 5 minutes at 170-240‹C.
