Summary:A thermoplastic molding composition P comprising: AB: at least one graft copolymer composition AB, consisting of at least one thermoplastic copolymer A and at least one graft copolymer B; C: at least one UV absorber as component C; and D: optionally at least one further additive as component D, wherein the UV absorber component C comprises at least one organic or inorganic component having an UV absorption at least in a wavelength range ≤ 380 nm; and wherein the UV absorber component C is at least partially selected from at least one black pigment, at least one white pigment and/or at least one dye having an UV absorption at least in a wavelength range ≤ 380 nm. Composition à mouler thermoplastique P comprenant : AB : au moins une composition de copolymère greffé AB, consistant en au moins un copolymère thermoplastique A et au moins un copolymère greffé B ; C : au moins un agent absorbant les UV en tant que constituant C ; et D : éventuellement au moins un autre additif en tant que constituant D, le constituant C absorbant les UV comprenant au moins un constituant organique ou inorganique présentant une absorption des UV au moins dans la plage de longueurs d'onde ≤ 380 nm ; et le constituant C absorbant les UV est au moins partiellement choisi parmi au moins un pigment noir, au moins un pigment blanc et/ou au moins un colorant absorbant les UV au moins dans la plage de longueurs d'onde ≤ 380 nm.
