ABSTRACT:
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.
