IR-reflecting compositions |
| 摘要 |
A composition comprising multistage polymeric particles having an average particle diameter from 0.5 to 15 μm and a Vicker's scale hardness from 100 to 700 Kgf/mm2; and a film-forming polymer having Tg no greater than 80° C. The refractive index difference measured from 400 nm to 800 nm between the polymeric particles and the film-forming polymer is no greater than 0.02 and the average refractive index difference measured from 800 nm to 2500 nm between the polymeric particles and the film-forming polymer is at least 0.04. |

1. A film comprising polymeric particles having: (a) an average particle diameter from 0.5 to 15 μm; and (b) a Vicker's scale hardness from 100 to 700 Kgf/mm2; and a continuous polymeric phase having Tg no greater than 80° C.; wherein an average refractive index difference measured from 400 nm to 800 nm between the polymeric particles and the continuous polymeric phase is no greater than 0.02 and an average refractive index difference measured from 800 nm to 2500 nm between the polymeric particles and the continuous polymeric phase is at least 0.04; and wherein an average distance between the polymeric particles is from 0.9 to 14 μm. |
