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.
一种像素形成着色剂组合物含有至少一种绿色着色剂,该绿色着色剂选自由下列颜料(A)和(B)以及颜料衍生物(C)组成的组:(A)铜酞菁绿色颜料,该绿色颜料是由平均被 3.5 至 4.0 个溴原子的邻苯二甲酸及其衍生物中的至少一种与平均被 14 至 16 个溴原子取代且未被氯原子取代的铜盐反应而得到的铜酞菁绿颜料;(B) 一种铜酞菁绿色颜料,由至少一种具有至少一个溴原子的邻苯二甲酸及其衍生物和至少一种具有至少一个氯原子的邻苯二甲酸及其衍生物的混合物与一种平均被不少于 12 个但少于 16 个溴原子取代且平均被不多于 4 个但多于 0 个氯原子取代的铜盐反应而得;(C) 通过在铜酞菁绿色颜料(A)和(B)中的至少一种中引入至少一个取代基而得到的绿色颜料衍生物。像素形成着色剂组合物适用于在彩色滤光片上形成三原色像素的 G 像素。
