Definitions
- the invention relates to protected against unauthorized copying Substrates and processes for their manufacture.
- GB-A-1 407 065 a way is shown, an original better of its Being able to distinguish counterfeit. Doing so will create an original Colorant combinations of colorants of similar hue are used, wherein at least one colorant is metameric. The original and its fake are to be distinguished from one another by comparison under certain lighting conditions.
- EP-A-428 828 describes two ways of using fluorescent colorants can come to copy-protected substrates.
- the first approach is based on a substrate on which a fluorescent and a non-fluorescent colorant similar hue are applied, so that the original shows a uniform color in normal light, and only at the color copy of the fluorescent color is falsified.
- the second The aim of the solution is to make a color copy of a substrate on which a fluorescent and non-fluorescent colorant is applied, look uniform allow. To do this, the fluorescent colorant is first copied and then a Colorant sought, which corresponds to the color of this copy, to be non-fluorescent Colorant in combination with the fluorescent colorant the substrate to be applied.
- the sensor While the eye does not distinguish between remission and emission radiation, and Perceiving both as an overall color impression, the sensor only measures the absorption and is blind to the emission radiation. This makes a difference in the determination of the color location compared to the optical impression and the surprising effect of color identity for the eye or the sensor.
- the invention is now directed to an emitting and a remitting To choose colorants so that the nuance when looking at not perceived Fluorescence is similar or the same.
- the invention relates to substrates with visible information attached to them, which are protected against unauthorized copying, which are characterized by that such a colorant combination is used to attach the information at least one emitting and at least one remitting colorant uses, whose color nuance when looking at not perceived Fluorescence is similar or the same, with the absorption maxima of the colorants a combination should not be more than 30 nm apart, the information is applied by the colorant combination so that the different color fields touching or lying close to each other.
- the invention further relates to methods for producing substrates with thereon attached visible information against unauthorized copying, thereby is characterized in that such a combination of colorants for attaching the information from at least one emitting and at least one remitting Colorants are used, the color shade of which when viewed at not perceived fluorescence is similar or the same, with the absorption maxima the colorants of a combination are not more than 30 nm apart, wherein the information is applied by the colorant combination that the different color fields touch or are close together.
- the remission colorant can be composed of several colorants, resulting in the possibility of an exact adjustment of the nuance to the Retroreflection spectrum of the emissive partner results.
- Suitable colorants for combinations are generally such that their absorption spectra look similar in position and band shape, the absorption maxima being no more than 30 nm apart, preferably no more than 20 nm apart.
- the half-wave width of the dyes in solution ie the spectral width of the longest-wave band at half maximum extinction ( ⁇ / 2 at ⁇ max. ) Should be ⁇ 150 nm, preferably ⁇ 100 nm.
- the fluorescent colorant can also consist of mixtures, which, however, must be structured in such a way that no absorption occurs within the emission band. It will preferably be colorants which absorb similarly to the remission colorant.
- the ink contains the colorants as color pigments or as plastic powders colored with dyes or polymer dispersions in binders customary for printing inks.
- the printing ink can also dissolve the dyes
- Suitable plastic powders are, for example, polyacrylonitrile, Polyester, polycarbonate, epoxy resins, Melamine-formaldehyde resins; are suitable dispersions for example styrene acrylates, polyurethanes or polyureas.
- Suitable pigments are all color pigments, preferably organic color pigments. They are a special form Salts of cationic dyes with poorly soluble Acids such as molybdate phosphate, tungsten phosphate, Molybdate silicate, tungsten silicate or suitable organic carboxylic or sulfonic acids.
- Suitable dyes for coloring plastic powders or polymer dispersions are all neutral or cationic Dyes that dissolve in these media or stain them well by salt formation or by reactive ones Groups can be built into the polymer.
- Another form of application of the invention is by coloring paper with one dye and printed a pattern with the other. Preferably becomes the remitting dye for coloring the paper used.
- the printing ink can be as described above be constructed.
- a Solution of the dye used in microencapsulated form become.
- Suitable dyes for dyeing the paper are all cationic or anionic dyes that have an affinity to have cellulose fiber.
- Suitable dyes for Microcapsules are all neutral dyes that stand out in the usual solvents for microencapsulation, such as aliphatic, aromatic and chlorinated hydrocarbons, solve sufficiently.
- solvents for microencapsulation such as aliphatic, aromatic and chlorinated hydrocarbons
- the number "10” was with the dispersion from c) of the example 1, the surrounding field with the dispersion from d) of Example 1 painted. Here too the eye could Read the number clearly, but it disappeared on the color copy.
