摘要:
An object is to provide a nonaqueous inkjet ink composition offering excellent wettability, fixing property, and discharge stability even when printed at high speed on targets whose printing surface is constituted by polyvinyl chloride, ethylene-vinyl acetate copolymer, or other vinyl polymer. Provided is a nonaqueous inkjet ink composition containing binder resin, pigment, pigment dispersant, and organic solvent, wherein such nonaqueous inkjet ink composition is characterized in that, as organic solvent, diethylene glycol ethyl methyl ether is contained by 40 to 80 percent by mass in the nonaqueous inkjet ink composition along with propylene carbonate contained by 7 to 50 percent by mass in the nonaqueous inkjet ink composition (excluding any composition that contains acetylene surface-active agent).
摘要:
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.
