Abstract

An aqueous inkjet printing ink including one or more reactive dyes, sulfolane and a buffer system and having a pH of not more than 7.0 when one or more of said reactive dyes have reactive systems of the vinyl sulfone series is prepared and used on textile fiber materials.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . An aqueous textile inkjet printing ink including one or more reactive dyes, sulfolane and a buffer system and having a pH of not more than 7.0 when one or more of said reactive dyes have reactive systems of the vinyl sulfone series.  
     
     
         2 . The printing ink of  claim 1 , including one or more reactive dyes in amounts of 0.01% by weight to 40% by weight, based on the total weight of said ink.  
     
     
         3 . The printing ink of  claim 1  and/or  2 , including 1 to 30% by weight of sulfolane based on the total weight of said ink.  
     
     
         4 . The printing ink of one or more of  claims 1  to  3 , including 1 to 20% by weight of organic solvents based on the total weight of said ink.  
     
     
         5 . The printing ink of one or more of  claims 1  to  4 , including one or more reactive dyes having reactive systems of the monochlorotriazine series.  
     
     
         6 . The printing ink of  claim 5 , adjusted to a pH of 7.0 to 9.0 by addition of a buffer system.  
     
     
         7 . The printing ink of one or more of  claims 1  to  4 , including one or more reactive dyes having reactive systems of the vinyl sulfone series.  
     
     
         8 . The printing ink of  claim 7 , adjusted to a pH of 3.0 to 7.0 by addition of a buffer system.  
     
     
         9 . The process for preparing a printing ink as claimed in one or more of  claims 1  to  7  by mixing the individual components.  
     
     
         10 . The use of a printing ink as claimed in one or more of  claims 1  to  8  in the inkjet process for textile printing.
