Definitions
- the present invention relates to a method for applying interference pigments to a substrate and to a substrate obtainable by the aforementioned method.
- EP-A-601 517 a white paper is printed with as little ink as possible in regular and irregular patterns. The ink only penetrates into the paper to a small extent.
- the disclosure of EP-A-601 157 has its application because of the low penetration of the ink into the paper, since the paper can subsequently be recycled like a white paper. The ink should therefore be easily removed from the paper.
- EP-A-681 060 discloses a process for producing differently colored paper wherein cellulose fibers and agglomerates of different thicknesses are used in the papermaking process and are applied to or incorporated into the finished paper. The cellulose fibers or agglomerates of different thickness are dyed prior to application or incorporation into the paper and are then incorporated into the paper pulp, which itself may have a different color.
- EP-A-439 363 discloses a paper containing or coated with desizing agents, as a result of which better absorption of the ink during the printing process is achieved by an ink-jet printing process.
- Desizing agent is dispensed into or uniformly distributed throughout the paper surface on this paper to provide an optimally printed copy.
- EP-A-518 490 discloses an ink for ink-jet printing wherein the ink contains a composition which facilitates the penetration of ink into the printed paper.
- EP-A-439 363 and EP-A-518 490 It is common to the teachings of EP-A-439 363 and EP-A-518 490 that the penetration of polar liquids, e.g. Ink jet inks, in the paper structure and in the paper fibers of the sized paper is facilitated by the use of suitable desizing agents.
- polar liquids e.g. Ink jet inks
- EP-A-439 363 nor EP-A-518 490 discloses the production of a patterned paper by non-uniform coloring of the paper surface using interference pigments.
- EP-A-1 239 077 proposes to apply a nonionic surfactant having a polyalkoxylene structure.
- EP-A-732 219 discloses a printing stock comprising a liquid-absorbent base material, an ink-acceptor layer coated on the base material, which is a pigment, a binder! and a cationic substance and a surface layer applied on the ink receiving layer composed of cationic ultrafine particles as inorganic particles.

It is thus intended to provide a substrate as a security element in which the incorporation of security features takes place in a form that makes it impossible for a potential counterfeiter to imitate them.
- the object of the present invention is achieved by a method for applying interference pigments to a substrate comprising the steps:
- the preparation contains at least one surfactant and at least one interference pigment, wherein the interference pigment has a carrier material and at least one coating applied to the carrier material.

- film-forming substances e.g. Solutions or dispersions of modified starches, resins or modified polymers, e.g. with the aid of a size press inside a paper machine, applied to the already formed paper web.
- the surface sizing also contributes to the strength of the paper, so that high-quality printing papers often have a sizing and surface sizing.
- the presence of surface sizing is not essential to the process of the present invention and, in addition, it is possible to use a substrate that does not have surface sizing and / or sizing.
- the process for producing a non-uniformly intensely colored substrate in step a) may include applying a dye solution in the form of a visible image or pattern to the substrate.
- a dye solution in the form of a visible image or pattern to the substrate.
- the preparation in step b) is applied in the form of a latent image or pattern.
- the image or pattern may be in the form of a representative image or an imaginary structure, a symbol, a uniform or irregular pattern, a mesh structure, or an uneven, e.g. random distribution of color on the substrate.
- the image or pattern can be applied either immediately after paper production, ie in still moist paper or on a subsequently produced dried paper, the paper then being dyed all over by means of an aqueous dye solution.
