Abstract

1,242,656. Hydroxyaniline derivatives. FUJI PHOTO FILM CO. Ltd. 20 June, 1969 [20 June, 1968], No. 31418/69. Heading C2C. [Also in Division G2] Compounds are disclosed of the formula where each of R and R<SP>1</SP> is H, halogen or an alkyl, hydroxyalkyl or alkoxy group of 1-4. carbon atoms. Compounds of the above formula where R and R<SP>1</SP> are each hydrogen or methyl groups adjacent to the -OH groups and the CH 2 is attached to the central benzene ring in m- or p-position are made by reacting paminophenol or 3-methyl-4-hydroxyaniline with terephthalaldehyde or isophthalaldehyde to form Schiff's bases which are then reduced with NaBH 4 .
