品のパール光沢も不充分である。However, in the method of obtaining pearl luster, in the method of kneading and dispersing the pearl pigment in the raw resin, the pearl pigment has a uniform and beautiful pearl due to poor dispersion of the pearl pigment at the time of melt-kneading the resin. There is a problem that gloss cannot be obtained, and the pearl luster of the obtained resin molded product is also insufficient.

も限定されるという問題点がある。In addition, in the method of obtaining a metallic luster by heating and melting and kneading the metal powder in the target resin, these metal powders improve the kneading effect in the resin and prevent ignition due to oxidation of the metal powder. Therefore, a metal powder pigment surface-treated with a higher fatty acid is used. By the way, higher fatty acids include substances that easily generate decomposition products when they are melt-kneaded with a resin at a high temperature, which causes a bad odor, which deteriorates the working environment and causes the odor. Therefore, there is a problem that the use of the molded product is limited.
