  • Patent number: 9644117
    Abstract: An adhesive compositions which shows a first color change when the ambient temperature is increased to a temperature of ?T1 and a second color change when the ambient temperature is lowered to a temperature of ?T2, wherein T1>T2. Such adhesive compositions have advantageous properties, in particular at security applications.
    Type: Grant

  • Publication number: 20050248147
    Abstract: The present invention relates to an individualized security document such as a passport, savings book or bankbook or the like which has a number of pages which are joined together by means of a fixing or adhesive. Incorporated into the security document by means of the fixing or adhesive is a transfer film which is provided with security elements and which has a base film and a decorative layer arrangement having the security elements. The decorative layer arrangement can be transferred onto the associated page of the security document. At the same time the base film is detached from the decorative layer arrangement and can be cut out of the security document.

  • Patent number: 6380131
    Abstract: Description of a color ribbon for thermo-sublimation print, comprising a carrier and a color layer formed on the carrier, with a sublimeable coloring substance disperse in a polymer binding agent, whereby a top coat is located on the color layer which contains a water-soluble cellulose ether. The cellulose ether preferably contains C1-C4-alkyl- or C1-C4-alkyl-hydroxyalkyl remnants and is specifically. Methyl-hydroxy-ethyl cellulose. The color ribbon has the advantage that the transferred color substance volume is selectively reduced with low print energies, that inside the ribbon spool there is no unwelcome color substance transfer onto the neighboring loops and that during the printing procedure there is no agglutination between the color layer of the color ribbon and the color receiving layer of the receiver foil.

  • Patent number: 6168656
    Abstract: Description of an inkjet ink for application in inkjet printers, comprising (a) a solvent, which contains at least 80% of a homopolar, non-watery solvent, (c) one or several phospholipides. In such inkjet inks, the phospholipides have a stabilizing effect. In some applications it may be beneficial with respect to certain pigments to employ an additional dispersant. The inkjet ink has, with concurrent high dispersing stability, significantly improved de-wetting property, with high optical density and excellent storage stability on a nozzle plate of an inkjet print head.
