Abstract
A film containing polymeric particles which have an average particle diameter from 0.75 to 15 μm and a refractive index which changes continuously from the center of the particles to the surface. The particles are embedded in a continuous polymeric phase comprising a polyolefin. The 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.
