Process for preparing metalized azo pigments |
| abstract |
Preparation of Aqueous-Stable Metalized Azo Pigment from 5-amino or 4-amino-2-chloro-toluene-5-sulfonic Acid and 3-hydroxy-2-naphthoic Acid with Calcium and Strontium Salts by diazotizing one of 2-chloro-5-amino-toluene-4-sulfonic acid and 2-chloro-4-amino-toluene-5-sulfonic acid, contacting the diazo with an inorganic salt of calcium, coupling the diazo with 3-hydroxy-2-naphthoic acid, and contacting the coupled diazo with an inorganic salt of strontium. The resulting metalized azo pigment exhibits high stability in aqueous coating compositions. |
