This purpose can reach by the safety element with feature that principal right requires.Method, the data medium of corresponding outfit and the authenticity examination method of safety element and data medium of this safety element made in explanation in independent claims.In the theme of dependent claims, further launch the present invention.
According to the present invention, general safety element comprises the substrate that has many particles.This particle is fit at least two diacritic information states of expression, thereby the variation between the information state is reversible, and can produce under the effect of gravity or external mechanical force.
When having only gravity to do the time spent, all particle is represented first information state.When the external mechanical force adjection, all particle is represented second information state.When the effect of external mechanical force changes or removes, make and have only gravity to do the time spent that all particles are represented first information state once more, or change over to and other the 3rd information state of the first and second information state phase regions.
Meaning according to information state of the present invention is as follows.Each particle all is in specific first state of expression first information.Whole formation first information states of first partial information of all particles.When external force is done the time spent, the corresponding state of particle changes, and each particle transmit can with first's other second portion information of the information area.Whole formation second information state of second partial information.
External mechanical force preferably tilts or shakes.
According to the present invention, " inclination " expression safety element is around the axis of any hope, preferably around the axis rotation that is made of safety element.
When shaking, safety element is moving forward and on the path backward, makes the formation oscillating motion.
The particle that shows information change when tilting is mounted to rotating, its corresponding surface is made up of at least two diacritic surf zones, and its corresponding mass centre and corresponding volumentary geometry center are not corresponding, and therefore, particle spatially is orientated in gravitational field.
In a preferred embodiment, be 90 degree to the maximum, when particularly preferably being angle of rotation or inclination angle and being 30-60 and spending, can be observed information change at angle of rotation or inclination angle.For example, this represents that for the observer that can recognize first information state after making safety element center on maximum 90 degree of suitable axis inclination, he can recognize second information state.According to the present invention, in particularly preferred embodiment, when going back, inclination can recover first information state again.
Preferably, this particle is the body with concave edge circle surface or spherical border surface, is preferably spheroid, cylinder, barrel-shaped body or ellipsoid, particularly preferably is spheroid.
Much less, the design of solid has more than the ideal situation of the perfect geometry designs of expression body, also comprises the body that departs from ideal situation.For example, the spheroid of the perfect body of geometry just do not represented in term " spheroid ", and the expression spherical structure.
Preferably, this particle is a molecule.This represent all yardsticks for example length or diameter all in micrometer range.
Particle diameter according to spheroid of the present invention is preferably 200 μ m or littler, is preferably 50 μ m or littler, is preferably 10-30 μ m especially.
Each surface of particle is made up of at least two diacritic surf zones.
Diacritic surf zone occupies at least three of particle surface/one separately, preferably occupies half of particle surface.Particularly preferably be, surf zone is not overlapping.When surf zone was not overlapping, its advantage was the character that can observe particle surface particularly well.
Certainly, also can on particle surface, provide diacritic surf zone more than two.Like this, see and have three or four diacritic surf zones easily.
Preferably, with unusual light instrument, particularly preferably be with bore hole and just can distinguish surf zone.
For example, magnifying glass, ultraviolet lamp, polaroid filter etc. just are suitable for and make light instrument.
In another embodiment, also available machines used difference of surf zone.By measuring with machine, may have difference with light instrument or the also appreciable character of bore hole.But surf zone is preferably only in the properties difference of being measured by machine.
For example, a surf zone or at least two surf zones have magnetic, electrical, optical polarization and similarity in the nonvisible wavelength scope that absorbs and/or launch.
All particles or be but that a part of particle can have the character that additional machine is measured in safety element.
By the character of magnetic and electricity, particle can additionally be controlled.
Particularly preferably be, these at least two surf zones are only different with the properties of measuring with machine only with the diacritic character of bore hole.
According to the present invention, the character of available bore hole difference is observer's (VIS) perceptible character in limit of visible spectrum.
Particularly preferably be, the spectral quality of surf zone for example absorbs, launches and/or reflect different.
For example, particle has two kinds of different in limit of visible spectrum colors.Color can form with variegating pigment.
In addition, since thin layered element or LC coating, different diffraction structure or luminosity etc., the interference difference that these at least two surf zones are suffered.
The diacritic character also mode of available any hope makes up.A surf zone can have color pigment, and another surf zone has luminescent substance.
The character of surf zone can contain all surfaces zones or be the subregion.For example, character can grid or other figure, character or digital form distribution.
The surface nature of all particles can be identical.Certainly, also can make a part of particle have other character.For example, white/black color combination that a part of particle can have, and other particles have indigo plant/red color combination.
Preferably, diacritic surf zone is produced by the surface of local vapor deposition.In addition, coating also can be produced by " cold coating ".
Moreover according to the present invention, the mass centre of particle is not corresponding with the geometric center of volume.This expression particle itself spatially is orientated in gravitational field.
When the Density Distribution of body was inhomogeneous, mass centre and volume center misfitted usually.
For example, by on the surface, carrying out local coating, can reach uneven density with suitable proportion.
Because the density difference, itself spatially is orientated particle.As a result, diacritic surf zone itself is also at spatial orientation.
Make the uneven local coating of Density Distribution of body have the diacritic character of the surf zone of making.In this case, it is identical with diacritic surf zone to have a zone of different densities.
If surf zone difference but density is identical then can be added in the other coating with suitable proportion on the surface.
If add other coating, then this layer can be positioned at diacritic surf zone the next door or below.Preferably, be placed on below the local coating, this can make surf zone distinguish.
Except the character that influences density, this other coating under each situation of ultraviolet ray and/or infrared ray etc., can have machine only that measure with security-related character, for example, fluorescence, auroral polesization, absorption, emission, reflection.
