The reaction of keto acids (79) having no amino group with 3-alkoxy-diphenylamines (80) is used to synthesize 3 -anilinofluorans (81), especially near-infrared-absorbing fluoran compounds (Eq. 6). [Pg.190]

Table 7 shows melting points of a few near-infrared-absorbing fluoran compounds (81) thus prepared. [Pg.190]
