  • Patent number: 7615265
    Abstract: A novel recording material for the inkjet printing process has a substrate and an ink receiving layer which is applied on at least one side of the substrate, the ink receiving layer containing an inorganic pigment and an ink fixative comprising at least two substances. The first substance is a polyamine epichorohydrin and the second substance is a polyvalent metal salt. This recording material is characterized in that the first substance is a medium-molecular, branched polyamine epichlorohydrin condensation product, the ratio of the first substance to the second substance is between 3:1 and 16:1, the pigment makes up at least 80 percent by weight with a D50 particle size (Malvern) ranging from 4 ?m inclusive to 12 ?m inclusive, and the ratio of ink fixative to pigment ranges from 1:2 inclusive to 1:6 inclusive. The invention is further directed to a method for recording by the discontinuous inkjet printing process which uses the novel recording material.

  • Publication number: 20080157517
    Abstract: The invention relates to a novel security feature in the form of a luminescent marking for integration in a recording material. The security feature comprises a radiation layer (21) with luminescent components and a masking layer (2) with cavity pigments at least partly masking the radiation layer. The pigments in the masking layer (2) are fused by locally defined heal treatment into the form of a marking. The invention particularly relates to a heat-sensitive recording material comprising, in a preferred embodiment, at least one substrate (10), a heat-sensitive recording layer (30), an intermediate layer (21), between the substrate and the heat-sensitive recording layer in the form of a radiation layer with luminescent components and a masking layer with cavity pigments (2), the pigments of the masking layer (2) being fused in the form of a marking by locally defined fusion.

  • Patent number: 6861113
    Abstract: Recording paper includes a stock sizing and/or surface preparation, a front side for receiving recordings and a reverse side configured differently from the front. The reverse exhibits excellent printability coupled with improved drying of printing inks when using offset printing inks that contain functional pigments and in particular magnetizable particles, while preventing the printable ink and the functional pigments, in particular the magnetizable particles, from penetrating too deeply into the paper.

  • Patent number: 6440898
    Abstract: A heat-sensitive recording sheet having a substrate with a heat-sensitive recording layer which contains color formers and color acceptors which react with one another under the action of heat. In order to permit the detection of counterfeited documents without the additional use of aids such as UV lamps or chemicals, present in the heat-sensitive recording layer, as a security element, are pressure-sensitive microcapsules which contain one or more color formers in a solvent. The color formers react with the color acceptors, forming a color, after destruction of the microcapsules.
