FIELD: printing industry.
SUBSTANCE: invention relates to the field of protection of valuable documents against forgery and is designed for the instrument determining the authenticity of the protected printing products, such as all kinds of valuable documents. The valuable document has a marking comprising at least one inorganic compound with a crystal structure, doped with ions of rare earth elements, having the property of selective interaction with the radiation in the optical spectral range, characterised in that when exposed to radiation on it in a predetermined band of the optical spectrum the radiation of the compound only in this band of the spectrum has an excess over the temperature radiation with the final duration of 10-10 seconds and more.
EFFECT: improving the level of protection of the valuable document.
