Abstract:
A perimidine-based squarylium dye contains a compound represented by Formula (I), the compound containing an isomer A and satisfying the following formula: Pa≧95(%) wherein the isomer A is an isomer of the peak shown in the longest retention time among all peaks due to isomers obtained by analysis of the compound by means of reversed-phase high-performance liquid chromatography, and Pa represents a value of the peak area of the isomer A relative to the peak area of all peaks.
