ABSTRACT:
An ink for ink-jet recording is provided in which copper phthalocyanine dyes and a thiazole-based compound are used. In this ink, the mildew resistant properties are not impaired, and the ink exhibits excellent ozone resistance. Furthermore, the formation of a precipitate is prevented in the ink although the thiazole-based compound is used. In the ink for ink-jet recording, as copper phthalocyanine dyes, two types of dyes are used together with a thiazole-based compound. Furthermore, about 1 mol % to about 20 mol % of the total counter ions in the two types of copper phthalocyanine dyes are ammonium ions or organic ammonium ions.
