Abstract

PURPOSE:To stabilize near IR absorption characteristics and to enhance sensitivity and reliability of a photodetector by incorporating a specified dye derived from an anthraquinone compd. or naphthalocyanine compd. CONSTITUTION:An intended near IR absorption film or plate contains a dye derived from an anthraquinone compd. represented by formula I (X, Y is H, nitro, or the like; R1 is C1-C16 alkyl or the like; and R2 is H or C1-C4 alkyl) synthesized from a compd. of formula IV, or a naphthalocyanine compd. represented by formula II or III (R3-R6 are each H, sulfonic acid, or the like; (o), (p), (q), (r) are each 1-6; and Me is a metal atom) obtained by reacting urea and a metal salt, such as zinc salt with naphthalene-2,3-dicarboxylic acid deriv.
