| titleOfInvention | Improvements in dyeing and printing by means of vat dyestuffs |
| abstract | In the process of developing dyeings and printings from ester salts of leuco vat dyes on the fibre by means of a developing bath containing an oxidizing agent other than a copper salt, a soluble sulphocyanide is added to the developing bath to protect the developed dyeing from over-oxidation. In an example, wool is dyed with the ester salt of 5 : 7 : 5<1> : 7<1>-tetrabromindigo, and developed in a bath containing ammonium sulphocyanide, potassium bichromate and sulphuric acid. Specifications 186,057 and 313,407, [both in Class 15 (ii), Dyeing, Processes &c. for], are referred to. |
