Abstract
A colorant for plastic containing a halogenated phthalocyanine pigment (A) that satisfies conditions (1) to (4) below: (1) the average number of halogen substitutions is at least 2.0 but not more than 7.0, (2) the halogen distribution width is at least 5, (3) the amount of aluminum phthalocyanine and halogenated aluminum phthalocyanine is not more than 1.0% by mass, and (4) the central element is at least one element selected from the group consisting of hydrogen, manganese, iron, cobalt, zinc, nickel and copper. As a result, a colorant for plastic can be shown that can color a resin without changing the mechanical or chemical properties of the resin, and in particular can produce a plastic molded article having essentially no migration, extremely low discoloration due to heat, and no deformation such as warping and distortion.
