ABSTRACT:
Disclosed is a biaxially stretched styrenic resin sheet obtained by biaxially stretching a resin composition comprising (A) a styrenic resin and (B) crosslinked styrenic fine particles-having an average particle size of 0.5 to 15 .mu.m and a refractive index if 1.5 to 20" in an amount of from 0.001 to 1% by weight based on the resin composition. The resin composition may further comprise (C) a rubber modified styrenic resin containing a rubber component having an average particle size of 0.1 to 4 .mu.m in such an amount that the rubber component concentration attributed to the rubber modified styrenic resin is from 0.005 to 0.1% by weight based on the resin composition. The styrenic stretched sheets exhibit improved blocking resistance owing to fine unevenness uniformly formed on the surface thereof while retaining the transparency. Even when a number of the sheets or formings obtained therefrom are stacked, they are easily separated apart without blocking.
