<p>A multilayered article of manufacture is disclosed. The article comprising a layer containing polycarbonate and a layer containing a copolyester. The repeating units of the copolyester are derived from dicarboxylic acids and from diols, where the repeating units derived from dicarboxylic acids contain 50 to 100% of units derived from terephthalic acid, 0 to 50% of units derived from isophthalic acid and 0 to 10% of units derived from other dicarboxylic acids, the sum of the proportions of the repeating units derived from terephthalic acid, isophthalic acid and other dicarboxylic acids is 100%, the percents being relative to the molar amount of the dicarboxylic acids. The repeating units derived from diols contain 0 to 97% of units derived from ethylene glycol, 0 to 97% of units derived from cyclohexanedimethanol and 0 to 3% of units derived from diethylene glycol and 0 to 10% of units derived from other diols, where the sum of the proportions of the repeating units derived from ethylene glycol, cyclohexanedimethanol, diethylene glycol and other diols is 100%, the percents being relative to the molar amount of diols. Also disclosed is a process for the production of the multilayered article of manufacture.</p> |
