Rigmentary salt of a triphenylmethane compound and process for making same |
| abstract |
Pigmentary Opal Sulfate is made by combining triphenylpararosaniline (Opal Blue) with a dilute acid. The pigmentary Opal Sulfate is a substitute for Alkali Blue. The most preferred process for producing the pigmentary Opal Sulfate involves drowning a solution of Opal Blue in a highly agitated solution of dilute sulfuric acid. |
