As described above, the present invention relates to a kind of method for being used to check the authenticity of secure file, particularly trust indenture,
Methods described includes at least one region, in the region or on the surface in the region, and the region has following logical
The reversible mechanoluminescence compound of formula：
Wherein, R represents to include the alkyl chain of 1 to 12 carbon atom.
Method for synthesizing this series compound is known per se, and especially in above-mentioned file WO-A-2011/
Described in 068537.
It is referred to as " transparent blind blocking " (transparent in standard trade surplus by using be especially available from SICPA
Blank the group of ink or varnish type can be made in colourless or almost colourless " intaglio plate " matrix (" intaglio " matrix))
Compound.
This matrix is main to be made up of dried plant oil, solvent, resin and additive (filler, drier).
Meet compounds of formula I above and this base is introduced in the content between 1 weight % and 10 weight %
In matter.This content is preferably 5%.
Then, this ink or this varnish are fixed on by bank note 1 according to one of method known to those skilled in the art
Composition trust paper on.
In Fig. 1 to Fig. 3 example, this is the homogeneous color region to form elliptical region 4.
Of course, it is possible to consider the other shapes in region, and their quantity can be variable.
According to compound I structures (change of chain R length) and the property of matrix (base gravure ink, offset ink, varnish),
Compound I can have different iridescent in the case where UV irradiates (symbol is R in figure).
For example, having blueness glimmering in base gravure ink for 5 weight % content, including the compound I of 12 carbon atoms
It is photochromic, and the compound I with 6 carbon atoms has green fluorescence in this same matrix.Symbol exists for C1 color in Fig. 1
It is uniform in whole varnish or ink.
Such case currently known in the art corresponds to Fig. 4 state A.
For both compounds, as long as the part in region 4 is subjected to friction (for example, by the edge of coin, the side of blunt
Edge etc.), fluorescence changes yellowly C2 (Fig. 2) from blue C1.
On Fig. 4, this corresponds to is transformed into state B from state A.Therefore, it is possible to " write " and shone by UV on the surface
" word " (writing) penetrated produced by display.
The change of iridescent is only observed in the part of mechanical disturbance.As shown in the figure 4, the invertibity of this attribute ensures
Removed in seconds by itself above-mentioned " word " within a few minutes or by heating (30 DEG C -50 DEG C) at room temperature.
In accordance with the invention it is possible to by applying the step of region 4 at least is heated at least 50 DEG C of temperature to enter
One step improves the authenticity of examination secure file.
Really, for these compounds, by providing heat, it can induce glimmering in the whole surface for be subjected to this thermostimulation
Photochromic change.This is Fig. 3 situation, and this is transformed into state C corresponding to Fig. 4 from state A.
The temperature that stopping heating and then restarting are heated to about 30 DEG C to 50 DEG C makes it possible to return to state A.
It should be noted that although state C is fluorescence, but the property that no longer there is power to cause fluorescence to change colour.In other words,
Even if the region is subjected to friction, it does not also change color partly.
Region 4 with the state B (being obtained by friction) shown in Fig. 4 can be heated (at least 50 DEG C) to be transformed into
State C.Original state A is returned to realize by above-mentioned low temperature heating step (30 DEG C -50 DEG C).
It is heated to be more than the time of 50 DEG C of the temperature generally between 1 second and 10 seconds.
Certainly, the melting temperature that the temperature obtained by region 4 is less than compound I is important.
Thus, the melting temperature of pure products is 158 DEG C, wherein, R=C12H25。
This temperature is variable according to the length of R group.
This method can obtain by friction or by providing heat significant fluorescence color change, and by heat come
Obtain the forfeiture that power causes fluorescence discoloration attribute.
To be common on varnish application to secure file, varnish completely or partially covers text in trust field
The print content and/or other safety elements shown on part.
In a kind of alternative solution, shown using the continuous film of polymeric material with completely or partially covering on secure file
Existing print content.
In both cases, this coating has defencive function.
Although the coating is present, as long as the thickness of this coating is without too big, with regard to that can see phenomenon as described above.
In fact, the people in street or businessman can be observed the fluorescence in the region by UV lamp and be checked by rubbing
Color change.
Bank can also be provided in the method for the application present invention with reference to UV lamp and the equipment of heater.
So equipment can also be incorporated into the automation classified for bank note.
Of course, it is possible to use the simple tool of such as hair-dryer or heating gun.
