    摘要: A dye acceptor element for thermosublimation printing comprising a support and a dye acceptor layer consisting essentially of polycarbonate arranged on the support, the polycarbonate containing 30 to 95% by weight aromatic carbonate structural units corresponding to formula I[--O--diphen--O--CO--] (I)in which diphen is the residue of a diphenol containing 6 to 30 and preferably 12 to 24 carbon atoms, and 70 to 5% by weight aliphatic polyether carbonate structural units corresponding to formula II[--O--polyether--O--CO--] (II)in which polyether is the residue of an aliphatic polyether diol having a molecular weight Mn of 600 to 20,000, is distinguished by high color density and a minimal tendency towards adhesion.
