An ink jet printing process having the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with ink jet recording elements having a support having thereon an image-receiving layer; C) loading the printer with an ink jet ink composition of water, humectant and a self-assembling colorant that is capable of spontaneously forming a nanoparticulate dispersion without any prior physical attrition or surface modification, the colorant having the formula: (A)m-Q-(Z)n wherein: Q represents a chromophore; each A independently represents an organic or inorganic group capable of hydrogen bonding or other non-covalent bonding; each Z independently represents an organic or inorganic group capable of electrostatic bonding; and m and n each independently represents an integer from 0 to 10; with the proviso that n+m is at least 1; and with the further proviso that at least about 50 wt. % of the colorant is present in the composition as particles; and D) printing on the image-receiving layer using the ink jet ink in response to the digital data signals.
