Description

Coated carriercr3ub3trot, ..... verzugowoioo with boidooitig untoroohiodliohon optical and / or fluorooziorondon characteristics-

The invention relates to a coated carrier substrate, which has different colored and / or fluorescent features on both sides viewed both in the incident and transmitted light. For a variety of applications in the field of security elements but also in the decorative field, in the packaging industry and the like, it is often desirable that an element, from both sides, a typical, unique but visually different appearance, regardless of whether the Element in the transmitted or transmitted light is considered.

In particular, in the field of security features for data carriers, value documents and the like contribute, among other security features such unique typical optical features essential for identification.

There are a number of combinations of different security features in a security feature known, for example, machine-readable features, combined with optical colored, luminescent (fluorescent or phosphorescent) features, surface structures and the like, the features viewed from different sides, may have different appearances.

In particular, when using colored or fluorescent features, achieving unique, typical visual appearances on both sides of the element is very difficult to achieve. ···· ·· 2 ·· ···· · «* ·· * ·

In the case of colored or fluorescent features, although the typical color or fluorescence color is clearly visible in reflected light on each side, a mixed color is produced by subtractive color mixing or a strong color in the case of fluorescent colors by additive color mixing lightened, incandescent fluorescence without typical fluorescent effect necessary for unambiguous identification.

It is irrelevant whether the different colors or fluorescent colors are applied on different sides of the at least semitransparent or transparent or translucent carrier substrate or on one side of the carrier substrate.

From EP 0 412 492 it is known, for embossing foils, in particular hot embossing foils, to introduce an intermediate layer containing a metallic pigment so as to prevent a pattern from showing through when viewing a second pattern from the opposite side. This intermediate layer is opaque and applied over the entire surface.

The object of the invention was therefore to provide a structure for a coated carrier substrate which has typical different optical properties from both sides.

The invention therefore relates to a coated carrier substrate, characterized in that it has at least one security feature recognizable in the incident and transmitted light with different color or fluorescence features different from each other, the different color or fluorescent layers being separated from one another by an opaque layer ,

For example, carrier foils preferably comprise flexible transparent or translucent plastic foils, for example, PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, as the carrier substrate. ABS, PVC in question. The carrier films preferably have a thickness of 5 to 700 μm, preferably 8 to 200 μm, more preferably 12 to 50 μm.

The lacquer layer can be, for example, an adhesive lacquer layer or a release-transfer lacquer layer, it can be thermally or reactively crosslinked or crosslinkable by radiation, for example UV radiation, or can be crosslinked and additional properties such as Scratch-resistant and / or antistatic equipment or have chemical resistance. Both aqueous and solvent-based coating systems are suitable, in particular coating systems based on PE acrylate, PET acrylate, urethane acrylate, PVC, PMMA or epoxy acrylate.

The carrier substrate may be provided on one or both sides with a hot or cold seal adhesive or a self-adhesive coating.

The surface of the carrier substrate may be structured or unstructured, or be embossed, for example, with micro- or macro-lines, that is to say two or three-dimensional structures may possibly be present on the surface.

Furthermore, the carrier substrate may already have partial dye or lacquer layers.

On the optionally already partially coated or printed carrier substrate, a first color layer is applied, this layer having a certain color and preferably a fluorescent

Color layer is. However, this layer can also have a defined color gradient.

Subsequently, the opaque layer is printed on this layer. The ink forming the opaque layer can be solvent-based, solvent-free and / or water-dilutable. Suitable binders are all natural and synthetic binders. The printing ink is pigmented, the pigments used being T1O2 and / or ZnS and / or BaSO4 and / or Al2O3 and / or silicic acid derivatives and / or kaolin and / or talcum and / or feldspars.

The ink for the opaque layer preferably contains 5-40% by weight of pigments.

However, the opaque layer can also be, for example, a metallized layer which is produced by vapor deposition of metals and / or metal compounds. Particularly suitable for this are metals such as black-colored aluminum (unstoichiometric AixOy) and the like.

Onto this opaque layer, another color layer or fluorescent color layer different from the first color layer is subsequently applied.

The color layers and the opaque layer may be applied by any known coating method, such as screen, gravure, digital or flexographic printing, or by a roll coating method. The coating can be carried out over the entire surface or partially, in which case all three layers are applied in register. The opaque layer must in any case be applied in those areas in which both the first and the second color layer are present and are visible for identification. • · • · • ·

• · · · · · »· · · ···

i

By means of the opaque layer situated between the color layers, in particular the additive color mixture occurring when viewing fluorescence colors in transmitted light or the subtractive color mixture occurring in other colors is prevented. The colors then also appear in transmitted light with their typical optical properties, ie with the pure color or the typical fluorescence effect.

If appropriate, further functional and / or decorative dye or lacquer layers may then be partially applied.

These layers may be the same or different from the layers, which may already be partially present on the carrier substrate.

As such color or lacquer layers, in each case a wide variety of compositions can be used. The composition of the individual layers may in particular vary according to their purpose, that is to say whether the individual layers serve exclusively for decorative purposes or should be a functional layer or whether the layer should be both a decorative corn and a functional layer.

The layers to be printed may be pigmented or unpigmented. As pigments, it is possible to use all known pigments, for example titanium dioxide, zinc sulfide, kaolin, ATO, FTO, aluminum, chromium oxides and silicon oxides, as well as colored pigments. In this case, solvent-based coating systems and systems without solvents can be used.

Suitable binders are various natural or synthetic binders.

For example, the functional layers may have certain electrical, magnetic, chemical, physical and also optical properties. •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• · · · · ·

To adjust electrical properties, such as conductivity, for example, graphite, carbon black, conductive organic or inorganic polymers. Metal pigments (for example, copper, aluminum, silver, gold, iron, chromium and the like), metal alloys such as copper-zinc or copper-aluminum or amorphous or crystalline ceramic pigments such as ITO and the like may be added. Furthermore, it is also possible to use doped or non-doped semiconductors, such as, for example, silicon, germanium or ionic conductors, such as amorphous or crystalline metal oxides or metal sulfides, as an additive. Furthermore, polar or partially polar compounds such as surfactants or nonpolar compounds such as silicone additives or hygroscopic or non-hygroscopic salts can be used or added to adjust the electrical properties of the layer.

To adjust the magnetic properties, paramagnetic, diamagnetic and also ferromagnetic substances, such as iron, nickel and cobalt or their compounds or salts (for example oxides or sulfides) can be used.

The optical properties of a partial layer which may be present can be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV region or in the IR region, effect pigments such as liquid crystals, pearlescent, bronzes and / or multilayer color change pigments and heat-sensitive inks or pigments. These are replaceable in all possible combinations. In addition, phosphorescent pigments can also be used alone or in combination with other dyes and / or pigments.

Various properties can also be combined by adding various additives mentioned above. Thus, it is possible to use colored and / or conductive magnetic pigments. All mentioned conductive additives can be used.

Especially for the dyeing of magnetic pigments it is possible to use all known soluble and non-soluble dyes or pigments. For example, a brown magnetic paint can be metallic, e.g., by adding metals in its hue, e.g. be set silvery.

For printing soluble layers, the ink or lacquer used may be soluble in a solvent, preferably water, but a dye soluble in any solvent, for example in alcohol, esters and the like, may also be used. The color or the colored lacquer can be customary compositions based on natural or artificial macromolecules. The color may be pigmented or unpigmented. As pigments, all known pigments can be used. Particularly suitable are TiQ2, ZnS, kaolin and the like.

If a soluble ink layer is used, it may optionally be removed after application of another layer in the process according to the invention by a suitable solvent, which is adapted to the composition of the ink layer, in order to be able to produce codings in the form of characters and / or patterns of any possible type.

Furthermore, for example, insulator layers can be applied. As insulators, for example, organic substances and their derivatives and compounds, for example, color and lacquer systems, e.g. Epoxy, polyester, rosin, acrylate, alkyd, melamine, PVA, PVC, isocyanate, urethane systems which may be radiation-curable, for example by heat or UV radiation.

These layers can be applied by known methods such as sputtering, sputtering, printing (e.g. gravure, flexo, screen, digital printing) and the like), spraying, electroplating and the like. The thickness of the functional layer is 0.001 to 50 μm, preferably 0.1 to 20 μm.

• ··· • · " •8th. · ♦ ·

Subsequently, the color layer is removed by a suitable solvent, which is adapted to the composition of the color layer. The application of paint is preferably water-soluble. Optionally, the separation can be supported by mechanical action.

In order to further improve the dissolution of the covered color layer, a thin pigmented color layer or a pure pigment layer may also be applied over the entire area or register, the thickness of this layer being approximately 0.01-5 μm.

By detaching the paint application with the areas of the functional layer above the paint application, the desired product is obtained.

Optionally, the coated film can also be protected by a protective layer or further refined, for example by laminating or the like.

The carrier substrate may be removed after application or remain on the product in one-sided coating. In this case, the carrier film may optionally be specially equipped on the uncoated side, for example, scratch-resistant, antistatic and the like.

FIGS. 1 and 2 show examples of a construction according to the invention.

Therein 1 is the carrier substrate, 2 the first color layer ^ 3 the intermediate layer ^ 4 the second color layer, 5 and 6 each a further functional layer and 7 a protective lacquer layer.

The coated carrier substrates according to the invention can be used as security elements in data carriers, in particular value documents, such as identity cards, cards, banknotes, as components and decorative elements in architecture and in other technical fields, and as packaging materials in the pharmaceutical or food industry. • ·

Examples:

Example 1:

On a transparent carrier film made of PET with a thickness of 12 pm, a fluorescent Farbervaufsschicht yellow-magenta-cyan is printed by digital printing, the total Veriaufslänge is 120 mm. Subsequently, an opaque layer consisting of 30% TiO 2 in methyl ethyl ketone with a binder content of 70% nitrocellulose is printed over the entire surface. A fluorescent simple cyan layer is printed on this opaque layer.

Both in the incident and in the transmitted light, the single-colored cyan layer without additive color mixing can be unambiguously identified from one side both the color process and from the other side.
