摘要： A compound is represented by the following formula (1). In the compound represented by Formula (1), at least one of R1 to R24 is a group particularly high electron withdrawing property, such as a sulfonic acid group and a carboxylic acid group or a group having the next highest electron withdrawing property to the sulfonic acid group and the carboxylic acid group, such as a halogen atom.

摘要： The present invention provides an ink that can achieve image characteristics for recording an image having excellent optical density, bleeding resistance, and white blur resistance and also can achieve reliability that provides excellent sticking resistance to a recording head. The ink is one for ink jet containing a first pigment and second pigment. The first pigment is a self-dispersible pigment to a surface of a particle of which a first functional group containing a phosphonic acid group is bonded. The second pigment is a self-dispersible pigment to a surface of a particle of which a second functional group not containing a phosphonic acid group but containing an anionic group other than the phosphonic acid group, and further containing another atomic group is bonded. The introduced amount of the functional group of the second pigment is 0.25 mmol/g or more.

摘要： Provided is an ink for ink jet including a first pigment and a second pigment. Each of the first pigment and the second pigment comprises a self-dispersible carbon black in which a functional group containing two phosphonic acid groups is bonded to a particle surface. The average particle size of the first pigment is smaller than the average particle size of the second pigment. The introduced amount of the functional group of the first pigment is higher than the introduced amount of the functional group of the second pigment.
