Abstract
An ink jet printing method is described. It comprising the steps of: providing an ink jet printer that is responsive to digital data signals; loading the printer with ink receptive substrates; loading the printer with an aqueous ink jet ink, said ink A) comprising a pigment, an aqueous carrier and potassium N-methyl-N-oleoyl taurate; and B) having a surface tension of 20 to 60 dynes/cm at 25.degree. C., a viscosity of 1 to 10 centipoise at 25.degree. C. and a particle size of less than 1.0 .mu.m; and printing on the ink receptive substrate in response to the digital data signals.
