Abstract

See full text

An object of the present invention is to provide a resin material capable of producing a molded body having few defects due to foreign substances, having high mechanical strength, very small in both orientation birefringence and photoelastic birefringence, and having high transparency, and having high transparency even when such a resin material is stretched. Provided is a resin composition containing a resin (A) and a multilayer structure polymer (B), wherein the multilayer structure polymer (B) has a crosslinked polymer layer and a hard polymer layer, and the hard polymer layer has at least two different hard polymer layers, at least one of which is a hard polymer layer (C) opposite in sign of a photoelastic constant to that of the resin (A).
