PROBLEM TO BE SOLVED: To provide an aqueous ink excellent in water resistance, light resistance, clarity, storage stability, without drying of a pen tip, and excellent in clarity and OA properties. SOLUTION: A cyano group-containing vinyl monomer (A) dyed with a dye, and a vinyl monomer (B) and a vinyl monomer (C) represented by the following general formula [R is a hydrogen atom or a methyl group, and Y is- CH 2 — or —CH 2 —CH (CH 2 X) - represents the (X is a halogen atom), n is an integer of 1 to 5. Aqueous ink containing resin particles comprising a copolymer containing one or both of the above as constituent monomers. Embedded image |
