A resin composition comprising (A) an elastomeric copolymer which comprises styrene
monomeric units and diene monomeric units, and (B) a copolymer which comprises
styrene monomeric units and (meth)acrylate monomeric units, which has a saturated
water absorption of 0.8% or less at a temperature of 60 C. and a relative
humidity of 90%, a flexural modulus of at least 1,800 MPa, a notched Izod impact
strength of at least 2 kJ/m2, a total light transmittance of at least
85% and a haze value of 5% or less when providing a sheet having a thickness of
2 mm, and a Vicat softening point of at least 90 C. This resin composition
can suitably be used as a base material of a sheet for a screen which has good
transparency, suffers from less deformation such as warp or deflection, and is
hardly cracked or chipped.
