Definitions

  • the present invention relates to a coated paper comprising at least one pseudo-watermark consisting of a mark giving the said paper a visual effect and a texture resembling those of a watermark.
  • the present invention also relates to a method for manufacturing a paper. coated according to the invention.
  • Watermarked papers are generally used in the field of security papers such as means of payment like banknotes or checks, and official documents such as passports, stamped papers, notarial acts, because the presence of the watermark limits the possibilities of photocopying and counterfeiting, and offers a means of recognition and / or authentication of said paper.
  • the watermark papers are also used in the field of personalized company papers by taking up in the form watermark the company logo, name or brand.
  • British patent GB-A-456,746 describes a coated paper having a watermark created by passing an air knife over a stamped area of the paper.
  • An object of the present invention is to provide a coated paper comprising pseudo-watermarks consisting of marks which locally modify the physical characteristics of the paper such as its mass volume and therefore certain properties such as its thickness and possibly its opacity.
  • Another object of the present invention is to provide a coated paper having pseudo-watermarks consisting of marks which create a contrast in brightness and / or shade with the rest of the coated sheet of paper.
  • Another object of the present invention is to provide a coated paper comprising pseudo-watermarks produced without the use of ink or varnish on its surface so that the composition of the paper in the areas constituting the pseudo-watermark is not not significantly changed.
  • Another object of the present invention is to provide papers coated with pseudo-watermarks whose usage properties, in particular printability properties in the areas of the paper surface corresponding to the said marks, are not significantly altered compared to blank coated paper.
  • Another object of the present invention is to provide a coated paper having pseudo-watermarks which can be produced in variable and small quantities under conditions more economical than by the processes of the prior art and which can be obtained by widths and quantities independent of the characteristics of the coating machine, in particular by a process allowing the implementation of modern coating machines high production capacity without modifying the actual coating operation.
  • Another object of the present invention is to provide a coated paper having a pseudo-watermark in which said watermark is produced after the last coating operation, i.e. at the output of the coater, possibly on the finished coated paper, i.e. off-line sleeping.
  • said rewetting solution is evaporated and the coated paper is densified in the areas where said solution was initially applied.
  • Said zones can then have an opacity contrast (reduction opacity) and / or a contrast of brightness (increase in brightness) and / or a contrast of color especially shade of color (color difference) with the rest of the sheet paper.
  • the opacity of the paper is partly linked to the presence of air in the fibrous interstices of the support or pigment interstices of the layer.
  • the solution replaces the air in said interstices.
  • the solution is evaporated and the fibers and / or the pigment layer being densified, the air gaps occupy overall a reduced volume and in particular are found in lower quantity that initially, which generates a de-opacification.
  • the densification of the layer and possibly of the support comes from a reduction thickness of the treated areas compared to the rest of the coated paper, the basis weight and especially the weight of the layer, remaining constant relative to the rest of the paper.
  • the surface mass is less in the areas clear because the fibers deposited are in smaller quantity compared to the rest of the sheet.
  • the surface mass is not constant because the weight of the layer is reduced in certain areas.
  • the contrast of opacity can result from the de-opacification of the layer alone, if the rewetting solution does not penetrate into the support and, in addition, the desopacificaton of the fibrous support if the quantity and nature of the re-wetting solution and / or the composition of the surface layer allow said solution to penetrate the support.
  • the rewetting of the surface layer facilitates the rearrangement of the pigments during calendering which can create an increase in gloss depending on the quantity and nature of the rewetting solution and according to the characteristics of the layer. In particular, depending on the size and the shape of the pigments these are more or less rearranged during calendering in step b) and the brightness contrast is more or less observable.
  • the determined rewetting zones define surfaces narrow such as fine lines defining characters or letters, the contrast of brightness in observation under reflected light is difficult to observe by an untrained eye.
  • the surface layer is a mat layer comprising size and shape pigments such as pigments cannot be rearranged even by calendering, no brightness contrast will be observed in said areas.
  • the method of the present invention can also create a modification of the color of the coated paper in said area (s) when said rewetting solution comprises a coloring agent, in particular a tinting coloring agent.
  • the contrast of color in the said zone or zones may also result from the modification of the opacity of the surface layer when there is a difference in shade initially between the support and the layer surface and / or between a first layer and a second surface layer because the nuance finished coated paper is actually a result of the nuances of the support and the different layers applied over the support.
  • the support and the layer have the same nuance, the contrast of nuance in the said zone or zones can only result from the addition of a shading additive in the fountain solution.
  • the support is less luminous than the layer.
