1. A polymeric masterbatch composition MB1 comprising:
a) a carrier material comprising a (meth)acrylic polymer AP1 comprising at least 50 wt % acrylic and/or methacrylic monomers in its polymeric chain, and
b) a polymeric silicone particle PP1 having a weight average particle diameter between 1 μm and 10 μm,
wherein the particle PP1 comprises between 0.5 wt % and 50 wt % of the composition based on a total weight of the components a) and b);
wherein the polymeric masterbatch composition MB1 further comprises:
c) a polymeric (meth)acrylic particle PP2 having a weight average particle diameter between 20 μm and 100 μm, wherein the polymeric (meth)acrylic particle PP2 represents between 10 wt % and 49 wt % of the composition based on a total weight of the components a), b) and c);
wherein the polymeric silicone particle PP1 and the polymeric (meth)acrylic particle PP2 are dispersed in the carrier material, and
wherein a difference of refraction index between the polymeric (meth)acrylic particle PP2 and the (meth)acrylic polymer AP1 is at least 0.005.
