Description: The present invention relates to a fiber-reactive phthalocyanine monoazo compound and a process for producing the same. The compounds are suitable as a fiber-reactive green dye used in a conventional dyeing or printing process for materials having a hydroxy group and/or nitrogen atom, particularly for cellulose fiber, natural or synthetic polyamide fiber, polyurethane fiber, leather or the like or a mixed fiber thereof. Phthalocyanine monoazo compounds usable for dyeing fiber materials in green color are described in JP-A-1-221460, JP-A-2-115276, JP-A-4-261470, etc. Hitherto, various kinds of reactive dyes for dyeing fiber materials in green color have been widely used in the field of dyeing or printing fiber-materials. However, the present technical level is not satisfactory to satisfy the high demand level in properties required for a specific dyeing method or to satisfy the trend of these days toward higher demand in fastness of dyed materials. The known reactive dyes mentioned above are not satisfactory in dyeing properties such as temperature sensitivity, salt sensitivity, alkaline sensitivity, liquor ratio dependency and build-up property. Hence, more improved dyes have been strongly demanded. Particularly, superior build-up property has become very important these days, because demand level in economy of dyeing methods has been getting higher and higher. So far, when dyeing a fiber material in green color is conducted with a mixed dye of a phthalocyanine type blue dye such as Reactive Blue 21, and a yellow dye, it is often difficult to dye fiber materials evenly with good reproducibility, due to the differences between the blue dye and the yellow dye in affinity and diffusion property, etc. Hence, it is strongly demanded to solve the problems in dyeing properties of the conventional dyeing method such as uneven dyeing. The present inventors have conducted extensive studies to solve the problems of the conventional dye such as the difference in affinity and diffusion property and to develop a novel compound usable for dyeing fiber materials in green color which is satisfactory in evenness of dyeing, dyeing reproducibility, build-up property, fastness and other widely demanded properties as dyes.
