  An unsaturated polyester resin composition is provided comprising a hard unsaturated polyester component, a soft unsaturated polyester component and a cross-linking monomer. The soft polyester component contains a polyoxyalkylene segment having a molecular weight from 600 to 6000 in the backbone thereof and is dispersed in the hard polyester component forming fine particles having particle size not greater than 4 microns. The resin composition, when cured, exhibits a Tg corresponding to the hard polyester component from 100°C to 200°C and another Tg corresponding to the soft polyester component from -100°C to 0°C.

  An unsaturated polyester composition is provided comprising an unsaturate polyester component, a cross-linking monomer and as a modifier of the resin a polyoxyalkylene alcohol at least partially esterified with a polymerizable unsaturated carboxylic acid. The modifier is produced by esterifying the hydroxy group of a polyoxyalkylene mono- or polyalcohol at least partially with a polymerizable carboxylic acid such as maleic acid.

  A pixel-forming colorant composition contains at least one green colorant selected from the group consisting of the following pigments (A) and (B) and pigment derivative (C): (A) a copper phthalocyanine green pigment obtained by reacting at least one of a phthalic acid substituted on average with from 3.5 to 4.0 bromine atoms and a derivative thereof with a copper salt, substituted on average with from 14 to 16 bromine atoms, and substituted with no chlorine atom; (B) a copper phthalocyanine green pigment obtained by reacting a mixture, which comprises at least one of a phthalic acid having at least one bromine atom and a derivative thereof and at least one of a phthalic acid having at least one chlorine atom and a derivative thereof, with a copper salt, substituted on average with not less than 12 but less than 16 bromine atoms, and substituted on average with not more than 4 but more than 0 chlorine atom(s); and (C) a green pigment derivative obtained by introducing at least one substituent in at least one of the copper phthalocyanine green pigments (A) and (B). The pixel-forming colorant composition is useful for the formation of G pixels of three primary-color pixels on color filters.
