<P>PROBLEM TO BE SOLVED: To provide a colored composition and an inkjet recording ink, which suppress the bronzing and have favorable ozone gas toughness and high print density. <P>SOLUTION: A phthalocyanine having a specified structure and a phthalocyanine having a specified substituent are mixed and used to suppress association and break away from trade-off relation. The colored composition is hardly precipitated and is excellent in temporal storage stability even in a high-concentration aqueous solution, can adjust dye aqueous solution as raw material of ink for inkjet at a high concentration, and therefore, is advantageous in respect of storage and transport, and when preparing the ink, does not cause precipitation of dye or the like, and therefore, hardly causes deviation of the concentration. <P>COPYRIGHT: (C)2013,JPO&INPIT |
