1. An ink jet printing method, comprising the steps of:

A) providing an ink jet printer that is responsive to digital data signals;

B) loading said printer with an ink jet recording element comprising a non-absorbing substrate;

C) loading said printer with an ink jet ink composition comprising an aqueous ink jet ink composition comprising;

a pigment;

a polymer binder containing less than 25% of hydrophilic monomer by weight of the total polymer, which is dispersible but insoluble in aqueous media;

at least one surfactant; and

a humectant; and

D) printing on said ink jet recording element accompanied by a heating step using said ink jet ink composition in response to said digital data signals.
