Abstract:
A composition containing polymeric particles. The polymeric particles have an average particle diameter from 30 to 300 nm and a Vicker's scale hardness from 100 to 700 Kgf/mm2. The composition also contains a film-forming polymer having Tg no greater than 80° C. The refractive index difference between the polymeric particles and the film-forming polymer is at least 0.04.
