Abstract
An object of the present invention is to provide a carbodiimide type compound having high dispersibility and dispersion stability of pigments, fine resin particles, and pigment-resin composite fine particles particularly in a silicone dispersion medium; a pigment dispersion composition and a pigment-resin composite fine particles-containing dispersion composition preferably usable in a wide range of fields such as inks for solvent ink jet, liquid developers, and the like by using the compound; and a liquid developer using such a pigment dispersion composition and/or pigment-resin composite fine particles-containing dispersion composition. The present invention provides a carbodiimide type compound obtained by introducing a polysiloxane chain by reaction of a functional group of a polysiloxane chain-containing compound having the functional group reactive with a carbodiimide group with a carbodiimide group of a carbodiimide compound having a carbodiimide equivalent weight of 100 to 50000.
