| titleOfInvention | Determination of the remoteness of an event comprising the production of a cellulose-containing object for protecting an article from falsification |
| abstract | The invention relates a method for determining the time dating event of creation of an object made of a cellulose containing material and having on its surface areas with a coating and without coating, in which the results of measurements of the components of nuclear-magnetic resonance relaxation are used for determining the parameters of free induction signals and the density of protons in cellulose samples taken from the cellulose containing material surface layer with coated and uncoated areas, the value G of relative changes of the cellulose parameters are calculated using the formula: n G=K 2 /K 2 +Pr 2 /Pr 1 , n where: Pr 1 and Pr 2 is the density of protons in cellulose, on the area having no coating and the area with a coating, respectively, g/sm 3 10 6 ;n K 1 and K 2 are the degrees of crystallinity of the cellulose, on the area having no coating and the area with a coating, respectively, specified by the formula: nn K =1-5( T 2 *A d /T 2 * A k ), n where: T 2M and T 2 is the relaxation time of the short and long components of the free induction signal, respectively, in microseconds;n A K and A d are the maximum amplitude of the short and long components of the free induction signal, respectively, degrees; D is the time dating of object creation determined by the linear dependence G (D) of the value G on the changes of the parameters of the cellulose sample from the time dating D: nn G ( D )=[( G 2 −G 1 )/Δ t]·D, n n where: G 1 G 2 are the values of relative changes of the cellulose parameters in a relative units determined as mentioned above, through the given time interval Δt. n In this case the object is an article, its fragment, an area with a coating, a time dating event mark applied on the article. The method of protection of an article from falsification of time dating event of its creation is proposed, in which a mark is plotted on the article surface. The mark is made of a cellulose containing material and tightly fixed it on the article surface by means of a permanent connection providing destruction of the mark at its unauthorized removal from the article surface, and the external surface of the mark has areas without coating and with a coating applied when fixing the mark on the article surface. |
