The present invention provides a merocyanine compound with excellent light fastness and heat resistance, specifically, a merocyanine compound represented by general formula (I). Among said merocyanine compounds, compounds represented by general formula (II), particularly compounds represented by general formula (III) or (IV), are preferred in that synthesis is easy and heat resistance is high. Compounds represented by general formula (V), (VI), (VII) or (VIII) are even more preferable. The specific details of general formulas (I)-(VIII) are as described in the specification. |
