<p>A reactive dye composition comprising at least one alkylnaphthalenesulfonic acid/formaldehyde condensate and a compound represented by the following formula,
<Chemistry id="chema01" num="0001"><Image id="ia01" he="17" wi="44" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein D is an organic dye residue having at least one sulfo group, R; and R<Sub>2</Sub> are independently a hydrogen atom or a C<Sub>1</Sub> to C. alkyl group unsubstituted or substituted with a halogen atom or a hydroxy, cyano, alkoxy, carboxy, carbamoyl, alkoxycarbonyl, alkylcarbonyloxy, sulfo or sulfamoyl group, A is a phenylene group unsubstituted or substituted with one ortwo substituents selected from chlorine and bromine atoms and methyl, ethyl, methoxy, ethoxy and sulfo groups, or a naphthylene group unsubstituted or substituted with one sulfo group, x is a halogen atom, and Y is -SO<Sub>2</Sub>CH=<Sub>CH2</Sub> or -SO<Sub>2</Sub>CH<Sub>2</Sub>CH<Sub>2</Sub>Z in which Z is a group capable of being split by an alkali, which composition is very readily soluble in water and aqueous alkaline solution, so that a dyeing or printing of cellulose fiber materials can be effectively carried out even by one-bath pad dyeing or onephase printing methods to give a dyed product of a deep color having excellent levellness and no speck.</p> |
