Abstract
NEW MATERIAL:A 6-(2,3-dihydroindol-2-yl)fluoran compound of formula I (wherein R1 is H or lower alkyl; R2 and R3 are H, lower alkyl, benzyl, phenyl or naphthyl, where R2 and R3 may form a heterocyclic ring together with bonded N).
EXAMPLE: 2-Amino-6-(2,3-dihydroindol-2-yl)fluoran.
USE: A pigment for a recording material such as pressure-sensitive copying paper or hectographic carbon paper.
PREPARATION: An aniline derivative of formula II (wherein R is H or lower alkyl) is reacted with a benzoyl benzoate of formula III (wherein R' is R) in the presence of concentrated sulfuric acid at 0W80°C for several hr.
