The object of the present invention is to provide a molding thermoplastic resin material giving resin mold whose quality and value are substantially equal to original resin mold even in a case where said resin mold is recycled. To attain said object, olefin group rubber and/or acrylic rubber to which monomer(s) being the same or similar monomer as (to) monomer(s) composing said molding thermoplastic resin material is(are) graft-copolymerized to give said rubbers compatibility with said molding thermoplastic resin material is(are) added in said molding thermoplastic resin material to improve said equal quality recycling property (property that quality and value are substantially equal to original thermoplastic resin mold even in a case where said thermoplastic resin mold is recycled). Said olefin group rubber and/or said acrylic rubber has(have) excellent thermal stability, heat-resistance, ozone resistance, oxidation resistance, and durability and has(have) effect on improvement of impact resistance for said thermoplastic resin material which is substantially immutable against heat history affected by repeated recycles and said molding thermoplastic resin material of the present invention can be used as a resin material of equal quality resin mold whose quality and value are substantially equal to resin mold using virgin resin material even in a case where said resin mold is recycled.
