PURPOSE:To obtain a coloring which is insoluble in a carrier liquid and has excellent dispersion stability and drying characteristic and to improve the reproducibility or colors by specifying and combining a dye pigment and resin. CONSTITUTION:The toner essentially consisting of the coloring agent and binder is dispersed into the aliphat. hydrocarbon carrier liquid to be used for a color liquid developer. The dye pigment which is expressed by the general formula and is subjected to a flashing treatment with a resin having 50-120 deg.C softening point is used for the coloring agent. The coloring agent which is insoluble in the carrier liquid and has the excellent dispersion stability and drying characteristic is obtd. The yellow color liquid developer for electrostatic photography contg. such coloring agent as the toner component is prepd., by such coloring agent as the toner component is prepd., by which the reproducibility of colors is improved.
