Embodiment
In Fig. 1 to Fig. 3, be illustrated schematically as the front elevation of the secure file of bank note 1.But this can be the secure file of the another kind of type of such as visa or passport.Therefore, this is simple illustrative embodiments.
For the ease of reading accompanying drawing, the only monetary value of bank note, in this case, value " 10 " has been illustrated in the visible face 2 such as front.Certainly, may be effective to the back side 3 to description that front is done.
In trust field, normally used all or part of safety practice (hologram, safety line, watermark etc.) can be incorporated in this bill, but it can not automatically illustrate.
As mentioned above, the present invention relates to a kind of for checking secure file, the particularly method of the authenticity of trust indenture, described method comprises at least one region, in described region or on the surface in described region, described region has the reversible mechanoluminescence compound of following general formula:
Wherein, R represents the alkyl chain comprising 1 to 12 carbon atom.
Method itself for the synthesis of this series compound is known, and describes in above-mentioned file WO-A-2011/068537 especially.
By the composition using colourless or almost colourless " intaglio plate " matrix (" intaglio " matrix) being called as " hyaline impression " (transparentblank) in standard trade surplus that especially can derive from SICPA can make ink or varnish type.
This matrix forms primarily of dried plant oil, solvent, resin and adjuvant (filler, drying agent).
The compound meeting general formula I is above introduced in this matrix with the content between 1 % by weight and 10 % by weight.This content is preferably 5%.
Then, according to one of method known to those skilled in the art, this ink or this varnish are fixed on the formation trust paper of bank note 1.
In the example of Fig. 1 to Fig. 3, this is the homogeneous color region forming elliptical region 4.
Certainly, other shape in region can be considered, and their quantity can be variable.
According to the character of Compound I structure (change of the length of chain R) and matrix (base gravure ink, offset ink, varnish), Compound I can have different iridescent under UV irradiates (in figure, symbol is R).
Such as, for the content of 5 % by weight, the Compound I comprising 12 carbon atoms has blue-fluorescence look in base gravure ink, and the Compound I with 6 carbon atoms has green fluorescence in this same matrix.In Fig. 1, symbol is the color of C1 is uniform in whole varnish or ink.
The known at present this situation in this area corresponds to the state A of Fig. 4.
For these two kinds of compounds, as long as the part in region 4 stands to rub at (such as, by the edge of coin, the edge etc. of blunt), fluorescence is transformed into yellow C2 (Fig. 2) from blue C1.
About Fig. 4, this corresponds to and is transformed into state B from state A.Therefore, it is possible to " write " from the teeth outwards and irradiated " word " (writing) showing and produce by UV.
In the part of mechanical disturbance, only observe the change of iridescent.As shown in the figure 4, the reversibility of this attribute ensure that at room temperature within a few minutes or by heating (30 DEG C-50 DEG C) in seconds by self removing above-mentioned " word ".
According to the present invention, the step that can be heated to the temperature of at least 50 DEG C by being applied to region 4 described in major general improves the authenticity of examination secure file further.
Really, for these compounds, by providing heat, the change of iridescent can be brought out on the whole surface of standing this thermostimulation.This is the situation of Fig. 3, and this correspond to Fig. 4 be transformed into state C from state A.
Stop heating then restarting the temperature being heated to about 30 DEG C to 50 DEG C to make to turn back to state A.
Although the state C of it should be noted that is fluorescence, no longer there is the character that power causes fluorescence variable color.In other words, even if friction is stood in this region, it does not also change color partly.
(at least 50 DEG C) can be heated to be transformed into state C in the region 4 with the state B (being obtained by friction) shown in Fig. 4.Realize turning back to original state A by above-mentioned low temperature heating step (30 DEG C-50 DEG C).
Be heated to the time of the described temperature being greater than 50 DEG C usually between 1 second and 10 seconds.
Certainly, the melt temperature that the temperature that region 4 obtains is less than Compound I is important.
Thus, the melt temperature of pure products is 158 DEG C, wherein, and R=C
12h
25.
This temperature is variable according to the length of R group.
This method by friction or by providing heat to obtain the change of significant iridescent, and can obtain by heating the forfeiture that power causes fluorescence variable color attribute.
In trust field, will varnish application to secure file be common, the print content that varnish completely or partially overlay file manifests and/or other safety element.
In a kind of replacement scheme, the continuous film of application of polymeric materials is completely or partially to cover the print content that secure file manifests.
In both cases, this coating has defencive function.
Although described coating exists, as long as the thickness of this coating is too not large, just phenomenon as above can be seen.
In fact, the people in street or businessman can by UV lamp observe this region fluorescence and by the change of friction examination color.
Equipment in conjunction with UV lamp and heating arrangement also can be provided to bank to apply the method for the invention.
Such equipment also can be incorporated in the automation for bank note classification.
Certainly, the simple tool of such as hair-dryer or heating gun can be used.
