Surface-modified inorganic pigment, colored surface-modified inorganic pigment, recording medium and production processes thereof, and image forming method and recorded image

摘要

The invention relates to a surface-modified inorganic pigment which has an inorganic pigment having acid function and an amorphous body located on the surface of the inorganic pigment having acid function and formed by at least a divalent or higher-valent metal and an anion component in a state where the inorganic pigment and the amorphous body do not chemically bond to each other, and which does not exhibit acid function.
