Due to the high temperature of 20°C, and as the residence time in the molding machine increases, that is, as the heat a history increases at high temperatures, the color tone of the molded product changes to black, which is a darkening phenomenon, and black streaks appear on the molded product. A problem has arisen in which so-called black streaks occur. The occurrence of such darkening and black streaks was even more remarkable when a volatile halogenated hydrocarbon was used as the binder solvent. These phenomena are particularly noticeable when the molded product is white or light-colored.

Next, the above colored composition was put into a 5 ounce in-line screw injection molding machine with a cylinder temperature of 300°C and a mold temperature of 150°C, and 30 shots were molded to obtain 30 colored injection molded plates of 5 cm x 9 cm. Ta. Using these 5th shots as a standard, the degree of darkening of the molded products of the 15th shot and the 25th shot was measured using a Colorcom-〇 spectrophotometer.
The color difference (ΔE) was measured to examine the degree of discoloration of the molded product.
