Pixel-forming colorant compositions and their use |
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.
