To provide a rubber-reinforced resin composition which is heat resistant and also transparent and is suitable as a molding material for a substrate for a transparent laminate laminated with a transparent film.

The rubber-reinforced resin composition contains 10-50 mass% of (A) a rubber-reinforced vinyl-based resin or a mixture of the rubber-reinforced vinyl-based resin and a (co)polymer of vinyl-based monomer (except for component (B) and component (C) below), 30-80 mass% of (B) a maleimide-(meth)acrylate-based copolymer and 10-60 mass% of (C) a (meth)acrylate-aromatic vinyl compound-based copolymer (the total of the component (A), component (B) and component (C) is 100 mass%). The total content of the rubbery polymers of the composition is 5-30 mass%. Its heat deflection temperature under load is 80C. Its total light transmission is 70%.
