    • A security document includes a substrate, and an imaging thermal coating on at least a portion of the surface of the substrate for thermal printing on the security document. The imaging thermal coating is soluble in one or more solvents. A warning message is printed on the substrate in an ink which is substantially insoluble in the one or more solvents. An obscuring coating on the substrate covers the warning message such that the warning message is not apparent to an observer. The obscuring coating is soluble in the one or more solvents, such that the obscuring coating is removed from the substrate if the document is subjected to washing with the one or more solvents to remove printed images on the imaging thermal coating. By this arrangement, an attempt to alter the security document by washing the security document with the one or more solvents is made apparent.
    • 安全文件包括基板和在基板的表面的至少一部分上的用于热敏打印在安全文件上的成像热涂层。 成像热涂层可溶于一种或多种溶剂。 在基材上以基本上不溶于一种或多种溶剂的油墨印刷警告信息。 衬底上的模糊涂层覆盖警告消息,使得警告消息对观察者不明显。 模糊涂层可溶于一种或多种溶剂中,使得如果文件用一种或多种溶剂洗涤以除去成像热涂层上的印刷图像,则将掩模涂层从基材上除去。 通过这种安排,通过用一种或多种溶剂洗涤安全证件来试图改变安全性文件是显而易见的。
