    摘要: An object of the present invention is to provide a material having spectroscopic properties, light resistance, solubility and thermal decomposition properties suitable for recording for DVD-R. More specifically, the present invention provides squarylium compounds in a state of a metal complex represented by the general formula (I): wherein, R1 and R2 are the same or different, and represent an alkyl group optionally having a substituent, an aralkyl group optionally;,having a substituent, an aryl group optionally having a substituent, or a heterocyclic group optionally having a substituent; Q represents a metal atom with a coordination ability; q represents 2 or 3; and A represents an aryl group optionally having a substituent, a heterocyclic group optionally having a substituent, or Y═CH— wherein Y represents an aryl group optionally having a substituent or a heterocyclic group optionally having a substituent.

    摘要: The present invention provides filters for an electronic display device comprising a squarylium compound represented by the general formula (I): wherein X represents a nitrogen atom or an oxygen atom; Q represents a carbon atom, a nitrogen atom, an oxygen atom or a sulfur atom; and R1, R2, R3, R4, R5, R6 and m are as defined in the specification. The filters for an electronic display device of the present invention can selectively shield the light having such a wavelength that reduces the color purity, and thereby can provide clear images.
