<p>PURPOSE:To improve spectral reflecting characteristic, spectral transmitting characteristic, and flowability by containing specified polyester resin and copper phthalocyanine pigment as a binder resin and a coloring agent, respectively. CONSTITUTION:A binder resin containing, as a main component, a polyester resin obtained by co-condensation polymerization of a diol component represented by a formula I, a divalent carboxylic acid or its acid anhydride or lower alkyl ester, and a trivalent or more polyhydric carboxylic acid or its acid anhydride or lower alkyl ester, or a trivalent or more polyhydric alcohol, in which the value of OHV/AV is 1.2 or more when the acid value of the polyester resin is AV and the hydroxy group value is OHV, and a copper phthalocyanine pigment represented by a formula (II) as a coloring agent are contained. In the formulae I and II, R represents a lower alkylene group, (x) and (y) each represent an integral number of 1 or more, wherein the average value of x+y is 2-7, and X<1>-X<4> represent hydrogen atom.</p> |
