| titleOfInvention | Disazo urea dyestuff solutions |
| abstract | Disazo Urea Dyestuff Solutions Abstract of the Disclosure A stable concentrated solution of an azo dyestuff is prepared by forming a tertiary alkanolammonium salt of an aminoazo compound of formula I, alone or in admixture with an aminoazo compound of formula II: formula I formula II where A and B each independently, in each occurrence is a naphthylene or phenylene group, and thereafter phosgenating in aqueous solution while maintaining the desired pH with a lithium base. The dyestuffs formed are substantive to cellulose, e.g., paper, and the highly concentrated solutions obtained are stable. |
