The important document has a basis with various marking substances for its check. The first marking substance is entered into volume of a basis of an important document. The second marking substance representing phosphor, and the third marking substance representing a substance absorbing infrared radiation, in common are present at a printing paint in which structure they are applied on a basis of an important document in the form of a code. Thus the first marking substance is the phosphor emitting luminescent radiation in a radiation-absorbing region of the third marking substance.
EFFECT: realisation of an important document with a high-scale fake protection allowing to determine its value.
