Abstract

1381096 1,4-Bis-(21-isopropyl-61-methyl anilino)anthraquinone FUJI PHOTO FILM CO Ltd 3 Aug 1973 [5 Aug 1972] 37096/73 Heading C4P [Also in Division G2] 1,4-Bis-(21-isopropyl-61-methylanilino)anthraquinone is claimed per se. The dye is prepared by heating together 1,4,9,10-tetrahydroxyan- thracene and 2-isopropyl-6-methyl-aniline in the presence of a dehydrating agent, e.g. boric acid or a boric acid ester of an alcohol. The combination of a 2-isopropyl and 6-methyl group gave the optimum degree of steric hindrance, colour, and sublimation resistance. The compound is useful for the melt-dyeing of polyethylene terephthalate, which may then be formed into a blue-dyed radiographic base film for use with medical X-ray photography.
