The invention relates to a radiation-curable precious-metal preparation, in particular a bright-gold preparation, that contains—in addition to a gold compound, which in particular is soluble in the printing medium, and further customary organometallic compounds—a radiation-curable, in particular UV-curable, printing medium, the polymerisation being initiated by the UV radiation and proceeding in accordance with a cationic mechanism which may optionally be assisted by y process that takes place simultaneously in accordance with a radical mechanism. The invention also relates to a transfer picture containing the precious-metal preparation, and to a process for decorating substrates that are suitable for decoration firing by direct application/printing and indirect printing (decalcomania).
