A test piece having this composition strength was produced by injection molding, and the black sharpness was visually judged to evaluate the colorability. “ ⁇ ” indicates that the jetness is sufficient and the colorability is excellent, and “X” indicates that the jetness is not sufficient and the colorability is inferior.
- a rubber-reinforced resin composition was produced and evaluated in the same manner as in Example 4 except that a predetermined amount of the compounding components shown in Table 3 was used. The results are shown in Table 3.
- a test piece having only the strength of rubber-reinforced resin [A-2] was prepared and evaluated in the same manner as in Example 4 above. The results are shown in Table 3.
- a rubber-reinforced resin composition was produced and evaluated in the same manner as in Example 4 except that a predetermined amount of the compounding components shown in Table 3 was used. The results are shown in Table 3.
- a rubber-reinforced resin composition was produced and evaluated in the same manner as in Example 4 except that a predetermined amount of the compounding components shown in Table 3 was used. The results are shown in Table 3.
- a rubber-reinforced resin composition was produced and evaluated in the same manner as in Example 4 except that a predetermined amount of the compounding components shown in Table 3 was used. The results are shown in Table 3.
- a rubber-reinforced resin composition was produced and evaluated in the same manner as in Example 4 except that a predetermined amount of the compounding components shown in Table 3 was used. The results are shown in Table 3.
- Comparative Examples 3 and 4 do not use the rubber-reinforced resin of the present invention, so the impact resistance is Although sufficient, the coefficient of dynamic friction and the specific wear amount were high, and the luminance was inferior and the luminance was inferior. Moreover, the weather resistance was also poor.
- the volume-average particle diameter of the polyorganosiloxane used to make the rubber-reinforced resin is as large as 290 nm.
- the property was also inferior.
- Examples 4 and 6 which have a small volume average particle size Onm of polyorganosiloxane, are well balanced in physical properties in terms of dynamic friction coefficient, specific wear, Izod impact strength, brightness and colorability. I understand.
- the example 5 in which polycarbonate was used as the thermoplastic polymer had a content of 80 I and + V force ⁇ Norrance.
