Classification: CPC C  B | IPC C

Claim 0:
1. An ink jet ink composition, comprising:
water; and
particles comprising a polymer having an anionic group, a photo-acid generator, and a sensitizer,
wherein a number of millimoles of the anionic group per 1 g of the particles is defined as an intra-particle anion value A, a number of millimoles of the photo-acid generator per 1 g of the particles is defined as an intra-particle photo-acid generator amount G, and a value obtained by subtracting the intra-particle photo-acid generator amount G from the intra-particle anion value A is −0.20 or more and 0.20 or less,
the sensitizer comprises at least one selected from the group consisting of a compound represented by the following Formula (S1), a compound represented by the following Formula (S2), and a compound represented by the following Formula (S3):, wherein, in Formula (S1), Formula (S2), and Formula (S3),
R11, R12, R21, R33, and R34 each independently represent a halogen atom, an alkyl group, an aryl group, a hydroxy group, an amino group, an alkylsulfanyl group, an alkylamino group, an alkoxy group, an alkoxycarbonyl group, an acyloxy group, an acyl group, a carboxy group, or a sulfo group;
n11, n12, n21, n33, and n34 each independently represent an integer of 0 to 4;
when n11 is an integer of 2 to 4, a plurality of R11 may be the same or different;
when n12 is an integer of 2 to 4, a plurality of R12 may be the same or different;
when n21 is an integer of 2 to 4, a plurality of R21 may be the same or different;
when n33 is an integer of 2 to 4, a plurality of R33 may be the same or different;
when n34 is an integer of 2 to 4, a plurality of R34 may be the same or different;
R22 and R23 in Formula (S2) each independently represent a hydrogen atom, a halogen atom, an alkyl group, or a hydroxy group; and
R31 and R32 in Formula (S3) each independently represent an alkyl group.
