1. A multi-layer article comprising:
i) a substrate layer including a polymeric composition, wherein the polymeric composition is a blend comprising: two or more polymers including a polycarbonate component and a toughening component, wherein the toughening component includes a styrene-acrylonitrile copolymer and an impact modifier; wherein the impact modifier is a polybutadiene rubber, and
ii) a cover layer having a thickness of 3 mm or less and including a polyurethane and/or a polyurea bonded directly to the polymeric composition of the substrate layer;
wherein the concentration of the two or more polymers is about 70 weight percent to 99 weight percent, based on the total weight of the polymeric composition, the total weight of the polycarbonate component and the toughening component is about 75 weight percent to about 100 weight percent, based on the total weight of the two or more polymers of the polymeric composition, and a weight ratio of the polycarbonate component to the toughening component is about 10:90 to 45:55 and a concentration of the polybutadiene rubber is 3 weight percent to 11 weight percent, based on the total weight of the polymeric composition;
wherein the amount of polyester in the polymeric composition is 0 to 1.9 weight percent, based on the total weight of the polymeric composition;
wherein the amount of any polyamide in the polymeric composition is 0.4 weight percent or less.
