Definitions

  • the present invention relates to a coated printable paper which can be used on machines fed sheet by sheet and by friction, this paper containing a conductive product.
  • the invention can be used more particularly in the field of indirect electrophotography which operates on the following principle: an electrostatic latent image of the original to be reproduced is formed on an adequate surface (for example the cylinder of a copier), develops this image by electrostatically attracting a toner there, then the toner image (which is no longer electrically charged) is transferred and fixed by applying pressure and / or heat to plain paper.
  • an electrostatic latent image of the original to be reproduced is formed on an adequate surface (for example the cylinder of a copier), develops this image by electrostatically attracting a toner there, then the toner image (which is no longer electrically charged) is transferred and fixed by applying pressure and / or heat to plain paper.
  • Indirect electrophotography therefore does not require the use of special paper whereas direct electrophotography and other types of electrographic printing use special papers on which an electrically charged latent image is formed, which image is then developed by direct electrostatic attraction of a toner on the paper.
  • These papers consist of an electroconductive base paper to ensure good dissipation of the electrostatic charges produced during these processes and they comprise a dielectric layer, this layer is photoconductive in the case of direct electrophotography.
  • Such papers are said to be dielectric, they are described for example in the article by RH WINDHAGER 'Characteristics of commercial electrographic sheets' TAPPI Printing Reprography / Testing Conf. (ATLANTA) Papers, 105-120 (Nov. 14-16, 1977). The invention does not relate to these special dielectric papers.
  • the machines which use the latter type of power supply are indirect electrophotography printing systems such as photocopiers and printers, in particular laser radiation printers, certain labellers, readers and sorters of checks.
  • indirect electrophotography printing systems such as photocopiers and printers, in particular laser radiation printers, certain labellers, readers and sorters of checks.
  • machine jams and / or poor quality or offset reproductions are observed, which originate in particular from poor leaf stripping of the sheets stacked in the machine feed trays.
  • the problem therefore occurs when feeding the machines.
  • This leaf stripping problem is all the more important as the sheet feeding speed is high. It has also been noted that the leaf stripping problem is greater when the coated paper is shiny.
  • the present invention therefore aims to provide a coated paper, whose layer weight on at least one side is at least 12 g / m 2 and having good leaf stripping on sheet feed systems and by friction machines having to process sheets of paper.
  • a second object is to provide modern coated paper having good leaf stripping on sheet feed and friction feed systems operating at high speed, that is to say processing at least about 50 sheets per minute.
  • Another object is to provide a modern coated paper which is shiny and which exhibits good stripping on sheet feed and friction feed systems, in particular on those operating at high speed.
  • the Applicant has surprisingly found that the aims of the invention can be achieved by incorporating a conductive product into the layer deposited on the paper.
  • uncoated papers currently suitable for reproduction by indirect electrophotography such as those sold by the Applicant under the brands OPALE de RIVES and REPRO 2000, have surface resistivities respectively of the order of 10 12 0hms and 3.10 11 ohms at 50 % relative humidity (measured according to ASTM D257-66); their static coefficients of friction are respectively 0.95 and 0.82 and their respective dynamic coefficients of friction are 0.62 and 0.58 (coefficients measured according to the method described in Example 1 below).
  • a control coated paper having the same composition as that according to the invention but without a conductive product has a surface resistivity of approximately 3.10 12 ohms and static friction coefficients of 0.55 and dynamic friction of 0.40 as shown in comparative example 1 given below.
  • the invention therefore provides a printable, non-dielectric coated paper, usable on machines fed sheet by sheet and by friction, coated on at least one side with a pigmented layer whose layer weight per side is at least 12 g. / m 2 in dry which is characterized by the fact that said pigmented layer contains at least one conductive product and that the surface resistivity of the coated face (s) is less than or equal to 10 11 ohms at 50% relative humidity, measurement according to standard ASTM D257-66.
  • the conductive product is of the anionic or neutral type.
  • the products currently used for layers for printing paper are of the anionic type, it is therefore necessary to choose conductive products ionically compatible with these pigments.
  • the conductive products are chosen from the salts of sulfonated polystyrenes or the nitrate salts. More particularly the conductive product is a sodium salt of a highly sulfonated polystyrene.
  • the coated side (s) of the paper have a gloss greater than or equal to 50, by determining the gloss at 75 degrees according to the TAPPI 480 om-90 standard.
  • the conductivity is not too high so that the coated side (s) can be printed correctly whatever the type of printing.
  • the sheet according to the invention contains a conductive product such that the coated side (s) of the sheet have a surface resistivity of between 10 8 and 10 11 ohms, measurement according to standard ASTM D257-66 for a 50% relative humidity.
  • the coated paper according to the invention has a water content of less than 5% to avoid problems of blistering of the pigmented layer.
  • the paper according to the invention has a porosity measured according to standard NFQ 03-075 of between approximately 10 -2 and 8.10 -2 cm 3 / m 2 .Pa.s.
  • the invention also relates to the use of coated paper on printing machines by indirect electrophotography fed sheet by sheet and by friction and which can process at least about 50 sheets per minute.
  • the paper is based on cellulose fibers; it can optionally include synthetic organic fibers or mineral fibers. It can also include fillers and other additives usually used in stationery.
  • the coated paper according to the invention has a grammage of at least 100 g / m 2 .
  • the layer comprises at least one binder, one or a mixture of fillers usually used for pigmented layers and a conductive product.
  • it may include additives used in the layers such as optical brighteners, lubricants, etc.
  • the paper is coated on both sides.
  • the layer is deposited on the support by any coating means used in stationery such as air knife coats, drag blade etc ...
  • the layer deposited on each side is 15 g / m 2 (dry matter)
  • the total water content of the paper is adjusted to 4.5%.
  • the coated paper is calendered to make it shiny, its gloss is 75.
  • Each side has an average surface resistivity of 5.10 12 ohms at 50% relative humidity. At 15% relative humidity this average resistivity is 36.10 12 ohms and at 90% relative humidity it is 12.10 8 ohms.
  • the static and dynamic coefficients of friction are 0.55 and 0.40 respectively.
  • KODAK stiffness is 0.80 mN / m.
  • porosity is 1.6.10 -2 cm 3 / m 2 .Pa.s.
  • GURLEY porosity measured according to ISO 5636 standard is greater than 5000 seconds.
  • This paper is cut into A4 sheets (21 x 29.7 cm), a stack of sheets is placed in the feed tray of a high-speed copier (50 copies per minute). There are problems with stripping from the start of the feeding, several sheets remain assembled to each other when they are driven in the machine.
  • Example 2 The same base paper and the same layer composition are used as in Example 1, while adding to the layer composition as conductive product the sodium salt of a highly sulfonated polystyrene and this at the rate of 6 parts by dry weight. .
  • the weight of the layer deposited on each side is 15 g / m 2 in dryness and the total water content of the paper is adjusted to 4.5%.
  • the paper is calendered as in Example 1. We characterize and test this paper as in Example 1.
  • Each face has an average surface resistivity of 3.10 10 ohms at 50% relative humidity. At 15% relative humidity this average resistivity is 10 12 ohms and at 90% relative humidity it is 8.10 7 ohms.
  • the static and dynamic friction coefficients are respectively 0.51 and 0.36; they are therefore little different from those of the coated control paper of Example 1.
  • KODAK stiffness, porosity and air permeability are unchanged from the coated test paper. Its gloss is 70.
  • This paper is cut into A4 sheets (21 x 29.7 cm), a stack of sheets is placed in the feed tray of a high-speed copier (50 copies per minute).
  • a stack of sheets is placed in the feed tray of a high-speed copier (50 copies per minute).

  • the paper does not cause any jamming (less than 1 sheet per 5000) during its passage inside the machine in single-sided application as in double-sided application.
  • the paper can optionally be printed in four colors by offset printing. We can therefore pre-print with offset, then customize by electrophotographic printing.
