Furthermore, in order to impart white color to the synthetic resin composition, a method is provided in which a white pigment such as titanium oxide, antimony oxide, or ubelide is added together with the glass, or a part of the glass is replaced with aluminum hydroxide. ing. However, in the above method of adding a white pigment, poor dispersion of the white pigment into the synthetic resin occurs, resulting in uneven color, and also reduces the corrosion resistance of the synthetic resin composition. It reduces the hot water resistance of the resin composition.
