A red leuco dye demonstrates unusually good thermal and photo stability. The red dye may be used with developers and wax carries for microencapsulation to form thermochromic pigments for use in inks, coatings and the like. This pigment is particularly desirable for use in metal-deco coatings, such as those used in aluminum cans in high beverage canning operations.
A charge control agent containing a barium salt of a sulfoisophthalic acid compound and optionally a metal salt of a salicylic acid compound. A toner for developing an electrostatic latent image comprising such a charge control agent, a binder resin and a colorant.

Alkylene oxide polymerizations are performed in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound provides several benefits including more rapid catalyst activation, faster polymerization rates and the reduction in the amount of ultra high molecular weight polymers that are formed. The catalyst mixture is unexpectedly useful in making polyethers having low equivalent weights.

3-(1-R-2-R1-5/6-Y-indol-3-yl)-3-(2-R2-4-N-R3-N-R4-aminophenyl)-X-phthalides,7-(1-R-2-R1-5/6-Y-indol-3-yl)-7-(2-R2-4-N-R3-N-R4-aminophenyl)furo[3,4b]-pyridine-5(7H)-ones and 5-(1-R-2-R1-5/6-Y-indol-3-yl)-5-(2-R2-4-N-R3-N-R4-aminophenyl)furo[3,4b]-pyridine-7(5H)-ones are useful as color formers in transfer imaging systems, pressure-sensitive carbonless duplicating systems and thermal-responsive marking systems. The phthalides are prepared by the interaction of the corresponding 2-(1-R-2-R1-5/6-Y-indol-3-yl)carbonyl-X-benzoic acid with the corresponding 3-R2-N-R3-N-R4-aniline or the interaction of the corresponding 2-(2-R2-4-N-R3-N-R4-aminophenyl)carbonyl-X-benzoic acid with the corresponding 1-R-2-R1-5/6-Y-indole. The furopyridines are prepared by the interaction of the corresponding 2/3-(1-R-2-R1-5/6-Y-indol-3-yl)carbonylpyridine-3/2-carboxylic acid with the corresponding 3-R2-N-R3-N-R4-aniline. The novel 1-R-2-R1-5/6-Y-indol-3-yl)carbonyl-X-benzoic acids and 1-R-2-R1-5/6-Y-indoles are useful as intermediates to the appropriate phthalides and furopyridinones.
