<p>The invention relates to a multi-layer product comprising a layer containing polycarbonate and a layer containing a copolyester. The repeating units of the copolyester are derived from dicarboxylic acids and diols. The repeating units derived from dicarboxylic acids are derived in proportions of between 50 and 100 mol % of terephthalic acid, between 0 and 50 mol % of isophthalic acid, and between 0 and 10 mol % of other dicarboxylic acids. The total quantity of repeating units derived from terephthalic acid, isophthalic acid and from the other dicarboxylic acids amounts to 100 mol %. The repeating units derived from diols are derived in proportions of between 0 and 97 mol % of ethylene glycol, between 0 and 97 mol % of cyclohexanedimethanol, between 0 and 3 mol % of diethylene glycol, and between 0 and 10 mol % of other diols. The total quantity of the repeating units derived from ethylene glycol, cyclohexanedimethanol, diethylene glycol and other diols amounts to 100 mol %. The invention also relates to a method for producing said multi-layer product, and to other products containing the cited multi-layer product.</p> |
