A method of preparing concentrated solutions of lithium salts of 1:2 complex metal azo dyestuffs |
| abstract |
Concentrated solutions of the lithium salts of possibly asymmetrical 1: 2 metal complex azo dyes in organic solvents are obtained by carrying out the neutral to alkaline coupling and the metallization without intermediate insulation and by adjusting the pH for the coupling reaction with lithium compounds which are alkaline in water. Asymmetric complexes are obtained either by first producing 1: 1 metal complexes and then reacting them with a metal-free azo or azomethine dye, or by adding a separately produced 1: 1 metal complex as a metallizing agent after coupling. |
