Abstract: An ink composition for inkjet printer including a cerium salt compound, a colorant and water; an ink cartridge including the same; and an inkjet recording apparatus including the ink cartridge. In the ink composition, the cerium salt can suppress the occurrence of kogation and properly eject ink droplets over a long period of time by forming a film on the surface of an exothermal device in a thermal type inkjet recording head.
Abstract translation: 一种用于包括铈盐化合物，着色剂和水的喷墨打印机的油墨组合物; 包括该墨盒的墨盒; 以及包括该墨盒的喷墨记录装置。 在油墨组合物中，铈盐可以通过在热喷墨记录头中的放热装置的表面上形成膜来抑制结焦的发生并且长时间适当地喷射墨滴。

CPC classification number: C09D11/322 , C09D11/037
Abstract: A self-dispersible colorant has a hydrophilic group incorporated into a colorant. A method of preparing the self-dispersible colorant reacts a cyclic anhydride with a reactive colorant in the presence of a Lewis acid. An ink composition comprising the self-dispersible colorant provides long-term storage stability and dispersion stability.
