3-(1-R-2-R.sup.1 -5/6-Y-indol-3-yl)-3-(2-R.sup.2 -4-N-R.sup.3 -N-R.sup.4 -aminophenyl)-X-phthalides, 7-(1-R-2-R.sup.1 -5/6-Y-indol-3-yl)-7-(2-R.sup.2 -4-N-R.sup.3 -N-R.sup.4 -aminophenyl)furo[3,4b]-pyridine-5(7H)-ones and 5-(1-R-2-R.sup.1 -5/6-Y-indol-3-yl)-5-(2-R.sup.2 -4-N-R.sup.3 -N-R.sup.4 -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-R.sup.1 -5/6-Y-indol-3-yl)carbonyl-X-benzoic acid with the corresponding 3-R.sup.2 -N-R.sup.3 -N-R.sup.4 -aniline or the interaction of the corresponding 2-(2-R.sup.2 -4-N-R.sup.3 -N-R.sup.4 -aminophenyl)carbonyl-X-benzoic acid with the corresponding 1-R-2-R.sup.1 -5/6-Y-indole. The furopyridines are prepared by the interaction of the corresponding 2/3-(1-R-2-R.sup.1 -5/6-Y-indol-3-yl)carbonylpyridine-3/2-carboxylic acid with the corresponding 3-R.sup.2 -N-R.sup.3 -N-R.sup.4 -aniline. The novel 1-R-2-R.sup.1 -5/6-Y-indol-3-yl)carbonyl-X-benzoic acids and 1-R-2-R.sup.1 -5/6-Y-indoles are useful as intermediates to the appropriate phthalides and furopyridinones.
