Carbonless duplicating systems |
| abstract |
3-[4-(Disubstituted-amino)phenyl] or (9-julolidinyl)-3-(diphenylamino)phthalides useful as color formers in pressure-sensitive and thermal marking systems are prepared by reaction of 2-[4-(disubstituted-amino)benzoyl] or (9-julolidinyl-carbonyl)benzoic acids with diphenylamines. |
