Reaction Steps

Dispersion 3 containing comparison solvents CS-2 and CS-3 and comparison stabilizer CST-1 has a high number of crystals. Use of the solvent of the invention with CST-1 reduces the number of crystals, as in Dispersion 4, but further improvement is achieved through the use of the solvent of the invention S-1 combined with stabilizer of the invention ST-1 as in Dispersions 5, 6, 7, and 9. The use of solvent S-3 with ST-1 and IC-7 also provided a dispersion with low crystals, as in Dispersion 10. The combination of the coupler of the invention and the solvent of the invention also provided a low crystal dispersion, as in Dispersion 9.
