A chromium complex compound represented as the free acid form by the formula (I): STR1 wherein X1 represents a hydrogen atom, a methyl group, a methoxy group or a sulfonic acid group; X2, X3 and X4 represent independently a hydrogen atom, a chlorine atom, a methyl gorup, a methoxy group, a carboxyl group or a sulfonic acid group; Y represents a hydrogen atom or a sulfonic acid group; Z represents a chlorine atom, a fluorine atom or --N30 (R)3 (R represents a C1 to C4 -alkyl group), STR2 and M represents a hydrogen atom or an alkali metal, a process for producing the chromium complex compound (I) and a method for dyeing cellulosic fibers with the same. The chromium complex compound represented by formula (I) is excellent in affinity to cellulosic fibers and in color-yield, build-up properties and fastness properties. These compounds are dyes for cellulosic fibers.
