摘要:
An ink-jet printing process using an ink containing a dye having an ionicity. The process includes the steps of: providing a cloth containing (a) a substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 100 to 700, or a nonionic surfactant having a molecular weight of from 100 to 700 and an H.L.B. of from 7 to 15, and (b) a polymeric substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 2,000 to 200,000; printing on the cloth with the ink; washing the cloth after printing; and drying the cloth.
