The present invention relates to a thermally curable powder coating composition based on hydroxy functional polyester resins with a high hydroxyl value blended with a low hydroxyl value resin and both cured with a self blocked uretdione, and its use in the preparation of a decorated substrate, by transfer printing. The transfer printing comprises the steps of : submitting a substrate to a treatment to prepare its surface for the application of a coating, applying a coating to the surface of the substrate in one or more cycles, covering the surface of the substrate with a sheet comprising a decoration which is to be transferred to said surface, and heating the substrate and the sheet comprising the decoration to effect the transfer of the decoration from the sheet onto the substrate. |
