INK COMPOSITION AND INK JET RECORDING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition not deteriorating a color tone, excellent in light resistance and storage stability of color image, useful for an ink jet recording method, containing a specific compound. SOLUTION: This composition comprises (A) a colorant and (B) a compound of formula I (R1 and R2 are each H, an alkyl, an alkoxy, an aromatic group or a heterocyclic group; R3 is H, an alkyl, an alkoxy, amidino, etc.; (n) is an integer of 1 to 3; (m) is an integer of 0 to 2; M is a pair salt). For example, a compound of formula II, etc., may be cited as the compound of formula I. A compound of formula III (R4 is H, an alkyl, carbonyl, etc.; R5 is H, an alkyl, amino, an aromatic group, etc.; R6 is an alkyl, an alkoxy, amino, etc.; X is an O atom or an S atom) such as a compound of formula IV may be used as she component B. The amount of the component B added is 0.01-15wt.% based on the total amount of the ink composition. A water-soluble dye is preferable as the component A.
