To obtain both a recording liquid, etc., for ink jets having a good hue, light fastness, etc., and a new methine compound having a good hue and a solid microparticle dispersion prepared by dispersing the methine compound in a medium.
This recording liquid for the ink jets comprises a solid microparticle dispersion prepared by dispersing a compound represented by formula (I) or (II) [wherein, A and B denote each an atomic group required to complete a conjugated double bond chain; Y and Z denote each an atomic group required to form a carbocyclic ring or a heterocyclic ring; L1, L2, L3, L4 and L5 denote each methine group which may respectively be substituted; Mk+ denotes a cation; X and X' denote each oxygen atom, sulfur atom or C(CN)2; m1 and n1 denote each 0, 1 or 2; x and y denote each 0 or 1; Mk+ denotes a k-valent cation; k denotes an integer of ≥1; and n denotes a number required to equalize the number of positive charges with the number of negative charges in the formula].
