An object of the present invention is to obtain a printed image having a high tinting strength and a clear hue, excellent dispersion stability, water resistance, light resistance and friction resistance, and a head for an ink jet recording apparatus. Provided are an inkjet ink capable of reducing partial clogging, a pre-dispersion of the inkjet ink used for the inkjet ink, and composite colored particles of the inkjet ink. A composite colored particle having an average primary particle diameter of 10 to 100 nm, comprising a filler composed of extender pigment particles or white pigment particles having an average primary particle diameter of 10 to 50 nm and colored pigment particles, wherein the filler is It comprises composite colored particles of an inkjet ink having a surface hydroxyl group content of 1.0 mmol / g or less, a predispersion of an inkjet ink using the composite colored particles, and an inkjet ink.
