Multi-layer composites comprising: (a) a first scratch-resistant coating layer comprising a first coating (primer); (b) a thermoplastic layer; and (c) a second scratch-resistant coating layer comprising a second coating (primer); wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are disposed on opposing sides of the thermoplastic layer; wherein the first coating and the second coating are not the same; and wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are selected such that a multi-layer composite having the first scratch-resistant layer disposed on both sides of the thermoplastic layer has a lower critical impact speed for tough/brittle transition at &#x2212;30&#xb0; C. according to DIN EN ISO 6603-1 than a multi-layer composite having the second scratch-resistant layer disposed on both sides of the thermoplastic layer; processes for producing the same; and uses therefor.
