Disclosed is a recording method including recording which includes attaching a color ink composition, which contains a coloring material, and a reaction solution, which includes an aggregating agent which aggregates components of the color ink composition, to a recording medium in no particular order, in which the color ink composition gives recorded matter with a glossiness at 60 of 60 to 100 when the color ink composition is individually attached to a recording medium with a glossiness at 60 of 80 to 100.

Disclosed herein are ink compositions comprising a self-dispersed pigment in a liquid vehicle. The liquid vehicle can comprise a solvent/water mixture in which the composition further comprises a surfactant system having limited solubility/compatibility with the liquid vehicle. Also disclosed are surfactant systems comprising at least a first and a second surfactant, where the first surfactant is selected from alkoxylated alkyne-containing alkylene diols and N-alkyl pyrrolidones, and wherein the first surfactant has a solubility of less than 0.5% in a 5% glycerol/water mixture, and where the a second surfactant is selected from acetylene alcohols comprising linear or branched C.sub.1-C.sub.14 alkyls, and alkoxylated phosphate esters.
