Problems solved by technology

[0009] However, this prior art does not provide the use of a combination of chemical solutions that, when visually observing the document, give a near colorless cumulative color that creates the illusion of being within the color coverage of conventional four-color printing
[0010] In addition, a common disadvantage of the methods used to manufacture multilayer compositions using layers and areas made of inks with daytime fluorescence without additional protective measures is that they use bright colors to attract attention, which in paper Such as securities, ID cards, bills or banknotes may not be suitable
So, on the one hand, a potential counterfeiter sees the presence of bright colors and will take steps to avoid the problem (because he is "heralded"), and on the other hand, because of the above-mentioned disadvantages (very bright "harmful" colors) These elements may be printed on prominent parts of ID cards or banknotes
[0011] Thus, the object of increasing the protection of multilayer compositions is not solved to a complete extent compared to the inventive method, since for the security of documents the prior art does not provide for the use of Possibility of raster-manufactured graphic elements of inks of near-colorless cumulative colors that give the illusion of lying within the color coverage of conventional four-color printing

example 1

[0037] (according to claim 1 with the features of dependent claims 5 and 11)

[0038] Documents of value or paper in the form of banknotes consist of three different colors that lie outside the color coverage of the CMYK color system - bright yellow, orange and bright blue ( figure 1 The reference numerals in 1)—the graphic elements in the form of alternating gratings made by the offset printing method.

[0039] The bright yellow ink includes 3-methoxybenzanthrone as a fluorescent compound with diurnal fluorescence in the visible spectrum under natural light, and the orange ink includes 3-methoxybenzanthrone with rhodamine C and rhodamine Ming 6G, and the bright blue ink includes arylethene substituted 2,5-diaryl oxazoles.

[0040] The combination and saturation of the colors and the grating spacing are such that the cumulative color of the graphic protection element is visually perceived as unsaturated and close to colorless.

example 2

[0044] (according to claim 2 with the features of dependent claims 5, 6, 11)

[0045] The document or paper in the form of a label consists of two different colors located outside the color coverage of the CMYK color system - bright yellow and bright blue ( figure 2 , image 3 )—a graphical element in the form of individual portions of alternating gratings with different pitches produced by the offset printing method.

[0046] Bright yellow inks include 3-methoxybenzanthrone, which is a fluorescent compound with diurnal fluorescence in the visible spectrum under natural light, and bright blue inks include arylethene-substituted 2,5-diaryl base oxazole.

[0047] The color combination and density of colors and grating pitch of the various portions of the graphic element are selected to create a predetermined visual perception of the geometry and size of the graphic element. exist figure 2 , the stripes of the vertical portion of the grating should appear to be curved inwar...

example 3

[0051] (according to claim 1 with the features of dependent claims 3, 9, 11)

[0052] plastic card( Figure 4 The document in the form of reference number 2) consists of two different colors located outside the color coverage of the CMYK color system - bright yellow and bright blue ( Figure 4 Reference numeral 3 in ) - a multilayer protective element formed of alternating graphic elements in the form of a grating made by the offset printing method, which is at least partially applied to the transparent surface of the card ("transparent window") part( Figure 4 On an additional layer in the form of reference numeral 4).

[0053] Bright yellow inks include 3-methoxybenzanthrone, which is a fluorescent compound with diurnal fluorescence in the visible spectrum under natural light, and bright blue inks include arylethene-substituted 2,5-diaryl base oxazole.

[0054] The color combination and density of the colors and the grating spacing are such that the cumulative color of t...

Abstract

The present invention relates to a multilayer protected composition, in particular to a multilayer paper product having specific properties against counterfeiting of securities or documents. The multilayer protected composition is formed with a further multilayer element formed on the surface of the paper and comprising at least A multicolor coating in the form of a periodic grating formed by two different colored inks. The ink comprises a luminescent compound with daytime fluorescence in the visible spectrum under natural light. The combination of inks is such that the cumulative color of the additional protective element is visually perceived as unsaturated and close to colorless. The multilayer protective element may form or be part of a graphic map that changes its The way it is displayed visually.

Description

technical field [0001] The present invention relates to the manufacture of compositions, in particular multilayer composite products and protective combinations of layers with specific properties, in particular protection against paper counterfeiting. [0002] Anti-counterfeiting compositions are used in the manufacture of securities and documents such as banknotes, passports, driver's licenses etc. where a high level of security is required. Background technique [0003] Technical solutions are known in the field of multilayer products that use, in various embodiments of RU 2264296, RU2199446, ink (paint), phosphor , Multiple layers of paint. [0004] Their disadvantage is that they are poorly designed for visual verification of the authenticity of protected paper and products made from protected paper such as banknotes and various forms of securities as well as excise stamps and postage stamps. [0005] The proposed invention is based on the use of multi-color solutions ...
