This carrier system carries at least one type of sensitizing dye described in (A) below and at least one type of sensitizing dye described in (B) below: (A) a sensitizing dye having a π-conjugated group and at least one anchor group, wherein the π-conjugated group and every one of the anchor group(s) are connected by a spacer having at least one alkylene and having an atomicity of 5 to 20; and (B) a sensitizing dye having a π-conjugated group and at least one anchor group, wherein the π-conjugated group and at least one anchor group are connected by a direct bond or by a spacer having at least one alkylene and having an atomicity of 1 to 4. In (A) and (B), the spacer is composed of carbon atoms, or carbon atoms and oxygen atom(s) etc., under predetermined conditions (see Description), and may have a branched chain or a ring structure.
该载体系统携带至少一种如下文(A)所述的敏化染料和至少一种如下文(B)所述的敏化染料:(A) 具有π-共轭基团和至少一个锚基团的增感染料,其中π-共轭基团和每个锚基团通过至少一个亚烷基且原子度为 5 至 20 的间隔物连接;(B) 具有π-共轭基团和至少一个锚基团的敏化染料,其中π-共轭基团和至少一个锚基团通过直接键连接或通过具有至少一个亚烷基且原子度为 1 至 4 的间隔物连接。在(A)和(B)中,间隔物由碳原子或碳原子和氧原子等组成、在预定条件下(见说明),间隔物可以是支链或环状结构。
