Abstract
A reactive dye composition which comprises a combination of 20 to 99% by weight of a dye represented by a free acid of the formula, ##STR1## and 1 to 80% by weight of an alkylnaphthalenesulfonic acid/formaldehyde condensate having a sulfonation degree of 50 to 150% and an average condensation degree of 1.1 to 3.0, which is very readily soluble in water and aqueous alkali liquors, resistant to coagulation when prepared into a color paste for printing, and useful for dyeing or printing cellulose fiber materials yellow with a high color yield, particularly by a one-bath pad dyeing method or printing method.
