ABSTRACT:
An aqueous liquid dye composition comprising 10 to 50% by weight of a fiber-reactive copper phthalocyanine dye represented by the following formula (I) in the form of a free acid, ##STR1## wherein Y is a group of --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z, in which Z is a splittable group by the action of an alkali, and m and n are independently a number of 1 to 3, provided that they satisfy the following formula, 2<m+n.ltoreq.4, 0.1 to 20% by weight of at least one cyclic imide selected from .epsilon.-caprolactam and N-methylpyrrolidones and the balance of water, which is chemically and physically stable, even when stored for a long period of time at ambient temperature or stored at a relatively high temperature such as 50.degree. to 80.degree. C.
