Abstract
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.
