Zusammenfassung:	Compositions and methods for producing a matte finish for plastics are disclosed herein. An exemplary thermoplastic article having a matte, printable surface is made of a thermoplastic resin and a thermoplastic additive composition having cross-linked silicone microparticles in a carrier resin. The composition can have 2.5% to 7.5% cross-linked silicone microparticles in a carrier resin, for example polyethylene terephthalate (PET). The cross-linked silicone microparticles have a particle size of about 2 [mu]m to about 15 [mu]m. The disclosed thermoplastic article can have a surface texture that is soft and smooth and a gloss level of less than 15 gloss units. 本申请公开了用于生产塑料用哑光涂饰的组合物和方法。具有哑光、可印刷表面的示例性热塑性制品由热塑性树脂和在载体树脂中具有已交联硅酮微粒的热塑性添加剂组合物制成。该组合物可在载体树脂，例如聚对苯二甲酸乙二醇酯(PET)中具有2.5％至7.5％的已交联硅酮微粒。已交联硅酮微粒具有约2μm至约15μm的粒度。所公开的热塑性制品可具有柔软看光滑的表面纹理和小于15个光泽单位的光泽度。
