Abstract

Vat dyestuff preparations are obtained by mixing vat dyes, or mixtures thereof with the amounts necessary for vatting of alkali meta-silicates, obtainable according to the process of Specification 391,407, [Group III], and anhydrous alkali hydrosulphite. Dispersing agents such as sulphite cellulose liquor and alkylated naphthalene sulphonic acids may be added. According to examples the vat dyestuffs pyranthrone, thioindigo, o-chlorbenzoyl-4-amino-1 : 9-anthra-pyrimidine, or monochloro- - N - dihydro - 1 : 2 : 2<1> : 1<1> - anthraquinoneazine are mixed with dry sodium meta-silicate, obtainable according to the said Specification 391,407, and with anhydrous sodium thiosulphate, with or without the dry sodium salt of an isopropylated or isobutylated naphthalene sulphonic acid, to give dry preparations. Specification 250,251, [Class 2 (iii)], also is referred to.
