Abstract

A penetrant liquid for ink jet textile printing includes a compound containing a lactam structure and water, in which the content of the compound containing a lactam structure is 20% by mass or more.

What is claimed is: 
     
         1 . A penetrant liquid for ink jet textile printing comprising:
 a compound containing a lactam structure and   water,   wherein the content of the compound containing a lactam structure is 20% by mass or more.   
     
     
         2 . The penetrant liquid for ink jet textile printing according to  claim 1 , wherein
 the compound containing a lactam structure includes at least one compound selected from the group consisting of 2-pyrrolidone, 2-azetidinone, 2-piperidone, ε-caprolactam, 4-ethyl-2-azetidinone, N-methyl-2-pyrrolidone, and 3-amino-2-piperidone.   
     
     
         3 . The penetrant liquid for ink jet textile printing according to  claim 1 , wherein
 the content of the compound containing a lactam structure is 30 to 50% by mass.   
     
     
         4 . The penetrant liquid for ink jet textile printing according to  claim 1 , further comprising a nonionic surfactant. 
     
     
         5 . The penetrant liquid for ink jet textile printing according to  claim 1 , further comprising a silicone-based surfactant. 
     
     
         6 . The penetrant liquid for ink jet textile printing according to  claim 1 , further comprising at least one organic solvent selected from the group consisting of a glycol ether having a boiling point of 260° C. or lower and an alkyl polyol having a boiling point of 260° C. or lower, and being substantially free of an organic solvent having a boiling point higher than 260° C. 
     
     
         7 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 1 .   
     
     
         8 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 2 .   
     
     
         9 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 3 .   
     
     
         10 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 4 .   
     
     
         11 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 5 .   
     
     
         12 . An ink set comprising:
 an ink composition containing a dye, and   the penetrant liquid for ink jet textile printing according to  claim 6 .
