    摘要： Disclosed is a pigment dispersant represented by the following formula (1):
    wherein X represents a hydrogen atom or an acylamino group; Y represents a specific aromatic group; Z represents a specific aromatic group or a C 2-30 aliphatic, alicyclic or heteroalicyclic amine reaction residual group having at least one amino group; G represents a reaction residual group of at least one compound selected from C 2-30 aliphatic, alicyclic and heteroalicyclic hydrocarbons each of which has at least one amino group; n is an integer of from 0 to 3; and when N stands for 0, Z represents a reaction residual group of a C 2-30 aliphatic, alicyclic or heteroalicyclic polyamine having at least two amino groups. A pigment dispersion making use of the dispersant and a color filter produced from the pigment dispersion are also disclosed.

    摘要： 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.

    摘要： Pigment dispersions for color filters are composed of pigments, dispersants, film-forming resins and liquid media. The dispersants comprises compounds represented by the following formula (I):
    wherein X and X' each independently represent H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino; Y represents an anthraquinonylamino, phenylamino or phenoxy group having H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino at the 4-position or 5-position; A and B each independently represent alkyl, cycloalkyl or aryl, and at least one of A and B has at least one substituent group containing a basic nitrogen atom; and Z represents H, CN, halogen, alkyl, alkoxy, NO 2 , benzoylamino or 3-benzoyl, and the 3-benzoyl group may be fused together with X to form an acridone ring. These pigment dispersions are useful for the production of color filters.
