<p>A composition comprising polymeric particles having an average particle diameter from 0.5 to 30 µm and Vicker's scale hardness from 100 to 700 Kgf/mm 2 . The composition also contains a film-forming polymer having T g no greater than 80°C. The average refractive index difference measured from 400 nm to 1100 nm between the polymeric particles and the film-forming polymer is no greater than 0.04.</p> |
