Abstract
Abstract The present invention relates to a heat transfer recording medium in which a substrate items of information such as an image and characters formed on a surface thereof by heat transfer and a transparent protective layer is provided on at least a part of the surface of the thus recorded information through an adhesive layer, if required, characterized in that the adhesive layer and/or protective layer function to provide security against counterfeiting. Combining information recorded by heat transfer with a function to provide security against counterfeiting, the present invention provides greater security against falsifying or counterfeiting.
