Claims18
An inkjet ink composition having a desired viscosity up to about 30 cps at 25° C., said inkjet ink comprising a soluble colorant, at least about 40% water (based on the total weight of the ink), and a polypropylene glycol of number average molecular weight (Mn) in the range of about 425 to less than 2000, wherein the amount of said polypropylene glycol in said inkjet ink is effective to impart said desired viscosity.
A method of inkjet printing comprising the step of printing a textile substrate with an inkjet printer by jetting one or more inkjet inks via said inkjet printer onto said textile substrate, wherein at least one of said one or more inkjet inks is an inkjet ink composition having a desired viscosity up to about 30 cps at 25° C., said inkjet ink composition comprising a soluble colorant, at least about 40% water (based on the total weight of the ink), and a polypropylene glycol of number average molecular weight (Mn) in the range of about 425 to less than 2000, wherein the amount of said polypropylene glycol in said inkjet ink is effective to impart said desired viscosity.
