Definitions

  • the invention relates to a method for treating a coating, in particular for fibrous substrates and films with laser radiation, wherein the coating consists of at least one binder, a laser-sensitive substance and an effect pigment.
  • the invention has the object of developing a generic security element such that the protection against counterfeiting is further increased.
  • the laser-sensitive substance undergoes a color change when exposed to the laser radiation.
  • the laser-sensitive substance is thus preferably converted or chemically reduced by the laser and in particular is not ablated or removed (chemically) oxidized or displaced by the action of the laser radiation, so that the effect pigment is not partially or completely exposed in the irradiated areas ,
  • the laser used is preferably an IR laser, ie a laser with an emission wavelength in the infrared wavelength range, preferably from 0.05 ⁇ m to 50 ⁇ m.
  • an IR laser is, for example, a carbon dioxide or CO 2 laser having an emission wavelength in the range from 9 ⁇ m to 12 ⁇ m, particularly preferably 10.6 ⁇ m, a diode laser in the wavelength range from 50 nm to 1100 nm or a solid-state laser in the wavelength range from 1000 nm to 1100 nm, particularly preferably 1064 nm.
  • the laser radiation of the IR laser causes molecular vibrations in the laser-sensitive substance, which in turn leads to kinetic energy and thus heat in the laser-sensitive substance and to a color change.
  • the color change of the laser-sensitive substance takes place particularly well when the laser-sensitive substance has a high IR absorption for the emission wavelength of the laser radiation used, so that the majority of the irradiated laser energy can be converted into heat and thereby the necessary temperature in the molecules of the laser-sensitive substance is achieved that they split and create colored connections.
  • Continuous, pulsed and quasi-pulsed lasers can be used.
  • the term "quasi-pulsed laser” is understood to mean a laser which switches on the laser at full power for a given switch-on time with a predetermined frequency and a predetermined switch-on time in percent of the resulting period duration.
  • the laser used is preferably operated in quasi-pulsed mode.
  • the pulse frequency here is 25 kHz, with a turn-on time of 25%, a forward speed of 2500 mm / s
  • the focus diameter of the laser beam is about 160 ⁇ m. If a surface is to be produced, in this example experience has shown that a line spacing of 0.1 mm makes sense.
  • a color change in the context of this invention is a change from one color to another color, for example from red to green, a change from a light hue to a dark hue, for example from light green to dark green, from a dark hue to a light hue or also a change from one contrast to another, for example from white or colorless to black.
  • Suitable binders are both solvent-based and water-based binders.
  • binders are preferred which have a high transmission for the wavelength of the laser radiation used, so that as much as possible of the laser radiation reaches the laser-sensitive substance and energy for the color change is present.
  • the laser-sensitive substance used is preferably a metal salt, more preferably an ammonium salt of molybdenum.
  • the color change in ammonium salts of molybdenum is therefore particularly good, since these high IR absorption for the emission wavelength of a CO 2 laser, so that the majority of the irradiated laser energy can be converted into heat and thereby the necessary temperature in the molecules of the ammonium salts of molybdenum is achieved, that they split and form colored compounds.
  • preference is also given to copper (II) oxalate or iron (II, III) oxide Fe 2 O 3 .
  • the laser-sensitive substance is particularly preferably colorless or white, so that the un-lasered areas appear in the usual gloss effect, as is known from coatings with so-called pearlescent pigments (somewhat attenuated by the laser-sensitive substance). If a color change is now induced in the laser-sensitive substance (eg from white to black) by, for example, necessary introduction of temperature or by laser irradiation, a kind of "background coloration" is produced, with the result that in these areas in combination with the pearlescent pigments a different color than the color the non-lasered areas becomes visible. Depending on which laser-sensitive material is used and which color change this shows (eg red, green, blue, etc.), different background colors and thus also different colors are created in connection with the pearlescent pigments. Preferably, a color change from white to black of the laser-sensitive substance used is used.
  • a background dyeing is particularly preferably produced by the action of the laser radiation, which changes or enhances the color and color saturation of the particular effect pigment used, but without changing the effect pigment itself.
  • a preferred such pearlescent pigment is, for example, "Merck Colorstream® T10-03 Tropic Sunrise", which exhibits interference effects from light green to bright red and pearlescence without laser-sensitive dye.
  • a mixture of this pigment with a laser-sensitive dye whose color change has already been made to black shows dark green with a slight color shift to dark red and when using longer-wave IR radiation such.
  • Another preferred pearlescent pigment "Merck Colorstream® T10-02 Arctic Fire” exhibits interference effects of bright without laser-sensitive dye Green to light purple and pearlescent.
  • Another preferred pearlescent pigment "Merck Iriodin® 225 rutile pearl blue” shows a light pearlescent blue without laser-sensitive dye.
  • Another preferred pearlescent pigment "Eckart Phoenix PX 1221 Gold” shows a light pearlescent gold without laser-sensitive dye.
  • the CO 2 laser radiation with an emission wavelength of 10.6 microns, glittering surface.
  • the color of the effect pigment used in each case is enhanced in the mixture with the laser-sensitive material by the laser irradiation, ie from a weak purple is an intense glittering purple, a light green, a dark green, etc.
  • the combination of these pigments with the laser-sensitive material thus allows different color changes and a wide range of different color changes due to the laser irradiation.
  • the glittering comes about especially when a high absorption of the corresponding laser wavelength is achieved in the coating and thereby the laser energy is efficiently converted into heat, which is usually in the use of long-wave IR radiation such.
  • the CO 2 laser radiation with an emission wavelength of 10.6 microns the case.
  • the surface of the coating is roughened heavily and the platelet-shaped effect pigments are exposed and set up.
  • the light is more broken and reflected. If the laser-sensitive substance has a high absorption of the corresponding laser wavelength, more laser energy is converted into heat and the Surface roughened even more. This will further enhance the sparkle.
  • the surface of a coating containing the pearlescent pigment "Merck Colorstream® T10-03" without laser-sensitive substance is not roughened as much as with the laser-sensitive substance, since the absorption of the laser wavelength used is not as high as in such effect pigments and their coating the absorption of the laser-sensitive substance for this wavelength.
  • a glittering effect can still be observed, even if this is not as pronounced as in the case of the coating with the addition of the laser-sensitive substance.
  • fine effect pigment particles with a diameter of less than about 10 ⁇ m generally produce a silky gloss
  • larger or coarser effect pigment particles with a diameter of about 10 ⁇ m to about 50 ⁇ m glitter with higher brilliance can then possibly also be attributed to the fact that the effect pigments of the laser melt the effect pigments and form larger agglomerates or pigment particles after cooling.
  • the combination of the laser-sensitive substance with effect pigments significantly enhances the security against forgery of the laser-induced color effects, since such glitter effects and color changes in connection with the register-accurate combination with a laser cutting of the substrate, such as WO 2010/072329 A1 is known, a security thread or a security strip can not be printed in the appropriate fineness and the register.
  • the mixture of the laser-sensitive substance and the effect pigments is colored with further color pigments.
  • these coloring pigments must not absorb the wavelength of the laser used so that they do not disintegrate into a different colored material and thus unexpected color changes of the coating after the laser irradiation come about.
  • the coloring of the mixture has the advantage that it is difficult for counterfeiters to recognize a relationship between the coating color and the color result after the laser irradiation.
  • a suitable and IR-transparent colored pigment e.g., red
  • protection from UV radiation and thus higher yellowing resistance of the coating can be achieved.
  • two or more surfaces are applied next to each other or in a pattern, wherein at least one surface has a laser-sensitive coating without effect pigment and at least one adjoining surface has a laser-sensitive coating with effect pigment.
  • different patterns, symbols or perforations can be lasered across the surface, such as those from WO 2010/072329 A1 or WO 2011/54112 A1 are known, so that there are two different, but accurate color effects.
  • two or more surfaces are applied next to each other or in a pattern, wherein at least one surface has a laser-sensitive coating with a color or an effect pigment that does not change color when the viewing angle changes (so-called color fix), and at least an adjacent surface has a laser-sensitive coating with effect pigment, which changes color when the viewing angle changes (so-called Colorshift).
  • color fix a laser-sensitive coating with a color or an effect pigment that does not change color when the viewing angle changes
  • colorshift which changes color when the viewing angle changes
  • the surface with color fix after exposure to laser radiation shows a green star, which does not change color when the viewing angle changes
  • the area with colorshift after exposure to laser radiation at a given viewing angle shows a blue stripe which changes when the laser beam is changed Viewing angle changes its color to the green color of the star.
  • two or more surfaces are applied next to each other or in a pattern, wherein after exposure to laser radiation at least one surface has a laser-sensitive coating with an effect pigment which changes color when the viewing angle changes (first color shift) and at least one adjoining surface has a laser-sensitive coating with other effect pigment that also changes its color when changing the viewing angle, but different (second colorshift).
  • first color shift an effect pigment which changes color when the viewing angle changes
  • second colorshift another effect pigment that also changes its color when changing the viewing angle
  • both surfaces change color, but both surfaces exhibit a different color shift effect.
  • the one surface shows a change in color from red to green as the viewing angle changes, while the other surface changes color from green to purple.
  • the colors of both surfaces coincide at a particular viewing angle.
  • the area with the first color shift at one viewing angle will show a blue star and the area with the second color shift a blue stripe, with both areas at another certain viewing angles change their color to green.
  • the area with the first color shift at one viewing angle shows a blue star and the area with the second color shift a green stripe, at another particular viewing angle the star turns green and the color changes Strip changes color to blue.
  • the color change and / or the non-changing color are possible both in the light of the visible wavelength range and in the non-visible wavelength range, for example in the ultraviolet wavelength range.
  • one surface shows a color change or a non-changing color in the visible wavelength range and another surface with fluorescent pigments a similar or different color change or a similar or different color in the ultraviolet wavelength range.
  • adjacent or contiguous in the sense of this invention is meant both a “direct” abutment without space between the surfaces, possibly also with a slight overlap, as well as an abutment with gap.
  • the lasering takes place in the form of a so-called negative pattern, wherein the surface is exposed to laser radiation over the entire surface and only a pattern, symbol etc. to be generated is not exposed to laser radiation.
  • a so-called negative pattern wherein the surface is exposed to laser radiation over the entire surface and only a pattern, symbol etc. to be generated is not exposed to laser radiation.
  • a laser-ablatable ink or other laser-ablatable material may also be printed as an adjacent surface or be applied.
  • the laser ablates this color or the respective substance and merges seamlessly with the discoloration of the other surface.
  • two areas of different color composition are printed on top of each other (also divided, regionally or in a pattern), wherein one surface has the laser-sensitive coating without effect pigment and the other surface has the laser-sensitive coating with effect pigment.
  • the present invention also makes it possible to use colored instead of black laser markers only by adding effect pigments to the laser-sensitive ink, the coloration is very difficult to see with the naked eye in the case of very thin lines which are colored by the laser.
  • the DE 10 2016 014 662 A1 describes a window lasered into the paper with, on the one hand, a see-through window area and, on the other hand, a colorshift or a blue / gold metallization. In this way, surprisingly interrelated designs can be produced on the front and back of the banknote.
  • the laser-sensitive material is based on the DE 10 2016 014 662 A1 further improving the sparkleness of very thin lines by printing the laser-sensitive material combined with color pigments or effect pigments such as Iriodin, Liquid Crystals, STEP pigments, fluorescent pigments or Colorshift-compatible pigments on the banknotes behind the security foil or where the window is should be placed.
  • the laser-generated window can be supplemented inline in one laser step by a laser-induced color effect in 100% registration to the window.
  • the window may, for example, be a laser hole, laser cut, filigram or a laser perforation.
  • the thin color effect lines show their color and their effect much better if the back of the security film, which is visible through the window, to the laser-sensitive material and color effect matching colors or effects (eg Colorshift, Fluo, gold-blue, LC etc .) shows.
  • Colorshift effects which also match (color-wise) to color shift effects of the security foil or correlate with it in a logical way, are also possible, as there are also Colorshift-capable effect pigments that have a color shift similar to that of the laser-sensitive material, but also of the laser-induced color effects enable.
  • Fluorescent pigments can also be mixed into the laser-sensitive substance and are very clearly visible in the ultraviolet spectral range. This results in further color combination possibilities, for example colors recognizable in the ultraviolet spectral range in combination with colors which can be recognized in the visible spectral range.
  • the lasered design on the back can be matched to or complement the design of security strips on the front of a bill. This also creates a logical correlation in the design of two different security features. For example, a security strip on its front coral and the same coral are mirrored as a color effect on the banknotes back lasered into the laser-sensitive material.
  • the area of the laser-sensitive material may be further printed in the design of the banknote to produce an additional appreciation of the banknote design.
  • the laser-sensitive material is executed in Iriodin blue, in addition a blue shell is visible through laser holes, in addition, a color effect is visible to match the shell color and the laser-sensitive material can also be printed in design. Further refinements in terms of color area size, color effect lines, and window size are possible depending on productivity.
  • the general color of the design composition can be increased if a different colored security film is visible through windows in the banknote substrate.
  • the laser-sensitive material can function as a backsize substitute.
