V. Description of the invention (/) [Background of the invention] (Please read the precautions on the back before filling out this page) The present invention relates to a dye composition capable of printing fiber materials, and particularly to a kind of cellulose fiber ( ceUulose fiber) or a reactive yellow dye composition for dyeing or printing of fibrous matter containing cellulose fibers. For the dyeing or printing of cellulosic fibrous material or cellulose-containing fibrous material, the reactive dyes required must have excellent performance in various properties, such as leveling, reproducibi output, solubility (solubility) and fastness (fastness), etc. Yellow reactive dyes must have high quality, especially in terms of deepness, reproducibility, color freshness, leveling, and detergency. In addition, they must make dyeing Or dyed products have excellent light fastness, sweat resistance, chlorine bleaching resistance, and high stability for a long time. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, however, commercially available yellow reactive dyes are generally available. When dyeing dark colors, the dyeing strength is not good and it is difficult to reach the desired dyeing depth; or the dyeing is good, but the dye color has red light; or it cannot be discharged and resist printing ); Or in cold pad batch dyeing, its' batch time is too long, and it is not suitable for short-term roll dyeing. Point. Therefore the yellow reactive dye is not always satisfactory. [3] Summary of the Invention The sheet scale applies China National Standard (CNS) A4 size (210 X 297 Kimiyoshi) 1225508
