Abstract

NEW MATERIAL:An anthraquinone dyestuff of formula I (X1, X2, X3, and X4 are H, 6W12C alkoxy group-containing anilino, or 6W10C alkylamino groups, at least two of them are H and at least one is anilino group contg. 6W12C alkoxy group).
EXAMPLE: The compound of formula I (X1 is formula II; X2, X3, and X4 are H).
USE: A colorant for "Flon" refrigerants and refrigerator oils, readily soluble therein to given a clear color, without decomposition under use conditions, and capable of facilitating the detection of leakage from apparatuses with clear spots.
PROCESS: A 1-halogenated anthraguinone, 1,4-, 1,5- or 1,8-dihalogenated anthraquinone is reacted with a 6W12C alkoxyaniline or further in addn. thereto a 6W10C alkylamine.
