  • Scratch Type Printed Material
    Publication number: 20080014379
    Abstract: A scratch type printed material that is hardly reproduced is provided. An area of a scratch layer 104 is smaller than an area of a release layer 103, and a printing layer 105 is formed on the portion of the release layer 103 protruding from the scratch layer 104, or the area of the scratch layer 104 is smaller than an area of a release layer 104 and the printing layer 105 is formed between the release layer 103 and the scratch layer 104 and on the portion of the release layer 103 protruding from the scratch layer 104, or a printing layer 501 made of temperature-indicating ink is formed on the scratch layer 104. As a result, when the scratch layer 104 is scratched off, the printing layers 105 and 501 are also partially broken, and the color of the printing layer 105 on the base material 10 becomes pale.
