Abstract: A resin composition contains: a resin containing a constituent unit (A) represented by general formula (1); and a resin containing a constituent unit (B) represented by formula (2) and/or a constituent unit (C) represented by formula (3). (R1 represents a methyl group or an ethyl group, R2 and R3 represent a hydrogen atom or a methyl group, and n represents 0 or 1.) (Ra and Rb represent a hydrogen atom, etc., Rh represents an aryl group of 6-20 carbons, X represents a single bond or a fluorene group, A and B represent an alkylene group of 1-4 carbons, m and n represent integers 0-6, and a and b represent integers 0-10.) (Rc and Rd represent a hydrogen atom, etc., Y represents a fluorene group, A and B represent an alkylene group of 1-4 carbons, p and q represent integers 0-4, and a and b represent integers 0-10.

Abstract: The present invention is able to provide a stretched multilayer thermoplastic resin film which comprises layers containing a thermoplastic resin (B) on both surfaces of a layer that contains a thermoplastic resin (A) and elastic particles, and wherein: respective intrinsic birefringences of the thermoplastic resin (A) and the thermoplastic resin (B) are within the range of from ?0.005 to 0.005; the content ratio of the elastic particles in the whole layer containing the thermoplastic resin (A) and the elastic particles is 5-40% by weight; the glass transition temperature of the thermoplastic resin (B) is 110° C. or higher and the saturation water absorption of the thermoplastic resin (B) is less than 1.1 wt %.
