Abstract
It is an object of the present invention to provide an aqueous ink for ink jet recording capable of recording a yellow image excellent in color developability and light resistance. An aqueous ink for ink jet recording contains a plurality of pigments and a resin dispersant. The plurality of pigments includes C.I. Pigment Yellow 74 and C.I. Pigment Yellow 138. A cumulative 50% particle diameter in volume-based particle size distribution of the C.I. Pigment Yellow 138 is 85 nm or less. A ratio of the cumulative 50% particle diameter in volume-based particle size distribution of the C.I. Pigment Yellow 138 to a cumulative 50% particle diameter in volume-based particle size distribution of the C.I. Pigment Yellow 74 is 0.72 times or less.
