PIGMENT COMPOSITION AND MIXED RAW MATERIAL USED THEREIN, AND PRODUCTION METHOD OF PIGMENT COMPOSITION

摘要

To provide a pigment composition that does not contain chromium or lead and has less toxicity, has a color suitable for a yellow line for a road sign, and is chemically stable and shows a small temporal change of color, and a mixed raw material used therefore, and its production method.SOLUTION: A pigment composition of the present invention is a pigment composition obtained by mixing praseodymium-containing zircon powder, colcothar powder, calcium carbonate powder, and a colorless transparent resin, in which relative to 100.0 pts.mass of the praseodymium-containing zircon powder, 1.2 pts.mass or more and 2.0 pts.mass or smaller of the colcothar powder, 180.0 pts.mass or larger and 300.0 pts.mass or smaller of the calcium carbonate powder, and 100.0 pts.mass or larger and 175.0 pts.mass or smaller of the colorless transparent resin are contained, and a total pts.mass of the praseodymium-containing zircon powder, the colcothar powder and the calcium carbonate is 281.2 pts.mass or larger and 402.0 pts.mass or smaller.SELECTED DRAWING: Figure 1
