ABSTRACT:
Novel and inexpensive coloring composites comprising inorganic substances as main component combined with organic basic colored compounds are provided. The inorganic substances are composed of at least one clay mineral selected from the group consisting of zeolite and montmorillonite. The combination of the inorganic substances with the organic basic colored compounds is based on ionic bond, and the combined quantity of the organic basic colored compounds amounts to 0.01-50%. Therefore, the coloring composites have a remarkably improved and stabilized coloring power and are also improved in such properties as thermal resistance, light resistance, acid resistance and the like. In addition, the coloring composites may also change in color according to the value of pH.
