This carrier carries a pigment (A) and a co-adsorbent (B) represented by the following general formula (1). (In the formula, ring A represents a 5- or 6-membered heterocycle which may be further condensed; the hydrogen atom in ring A may be substituted by a hydrocarbon group which may have a substituent, a halogen atom, a cyano group, a nitro group, a —OR2 group, or a —SR2 group; Z represents a divalent aliphatic hydrocarbon group interrupted 0-3 times by —O— or the like; Z1 represents a divalent aromatic group; R1 represents a carboxylic acid group, a sulfonic acid group, a phosphoric acid group, or a phosphonic acid group; R2 and R3 represent a hydrocarbon group which may have a hydrogen atom or a substituent; Anm− represents an m-valent anion; m represents an integer of 1 or 2; and p represents a coefficient for maintaining a neutral electric charge). |

1. A carrier system carrying a dye (A) and a co-adsorbent (B) represented by general formula (1) below: wherein, ring A represents a 5- or 6-membered heterocycle and may further be fused with another cyclic group; a hydrogen atom in the ring A may be replaced by a halogen atom, a cyano group, a nitro group, an —OR2 group, an —SR2 group, or a hydrocarbon group that has a substituent or that is not substituted; Z represents a divalent aliphatic hydrocarbon group that is interrupted zero to three times by —O—, —S—, —CO—, —COO—, —OCO—, —CONR3—, —NR3CO—, or —Z1—; Z1 represents a divalent aromatic group; R1 represents a group selected from a carboxylic acid group, a sulfonic acid group, a phosphoric acid group, and a phosphonic acid group; R2 and R3 each independently represent a hydrogen atom or a hydrocarbon group that has a substituent or that is not substituted; Anm− represents an m-valent anion; m represents an integer of 1 or 2; and p represents a coefficient for keeping the electrical charge neutral. |
