A new storage-stable solution of the reactive dyestuff of the formula ##STR1## wherein CuPc=the radical of a Cu phthalocyanine dyestuff, n m=1, 2 or 3, n n=1, 2 or 3, n m+n=3 to 4 and n M.sup.⊕ =H.sup.⊕, an alkali metal cation or an ammonium ion, n is provided. n The storage-stable solution according to the invention is characterized in that it contains 10-35% by weight of reactive dyestuff (1), 10-30% by weight of solubilizing agent, 0-10% by weight of anionic dispersing agent, 0-7% by weight of inorganic salts, such as Na 2 SO 4 , Li 2 SO 4 and the like, and 0.1-3% by weight of buffer (pH 4-7), the remainder to make up to 100% by weight being water. |
