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 called dielectric, they are described for example in the article by RH INDHAGER ⁇ 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 this latter type of power supply are printing systems by indirect electrophotography such as, for example, photocopiers and printers, in particular laser radiation printers, certain labellers, check sorters.
- the surface resistivity of the coated sheet must be at least 8 ⁇ 10 3 ohms for a relative humidity of 85% at 20 ° C. and therefore that it is necessary to use layer pigments which have a resistivity of high surface. This document will therefore not lead those skilled in the art to decrease the surface resistivity of the sheet, quite the contrary.
- leaf stripping is considered to be correct if jamming problems are observed for at most 5 sheets in a stack of 1000 sheets while in practice the minimum rate of jamming accepted is one sheet per 5000, the preferred rate being one sheet per 20,000.
- the surface of the sheet has been treated with conductive products which are such that they give the sheet a conductivity which varies little with the relative humidity rate, in particular with the low rates.
- 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.
- 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 n 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 u 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 ...
- a woodless backing paper weighing 102 g / m 2 , is coated on each side by a dragging device.
- the layer has the following composition, by dry weight: - calcium carbonate / kaolin 80 parts / 20 parts
- 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.
- the static and dynamic coefficients of friction are 0.55 and 0.40 respectively.
- 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.
- N.B . The coefficients of friction are measured according to the following method:
- the pad is 6.35 cm square and has a weight of 200g.
- the whole is placed on another sheet of the same kind as that to be tested, sheet against sheet.
- the skate is pulled at a speed of 200 mm / min.
- We measure the static (at the start of the displacement) and dynamic (maintenance of the displacement) forces to calculate the static and dynamic coefficients respectively according to the following equation: measured force (in Newton) / [skid mass (in kilo) xg ] with g 9.81 m / s 2 .
- 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. .
- Example 1 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.
- Each face has an average surface resistivity of 3.10 10 ohms at 50% relative humidity. At 15% relative humidity this average resistivity is l ⁇ 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 sample 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).
- the paper does not cause any jamming (less than 1 sheet for 5000) when it passes 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.
- 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 sodium nitrate and this at the rate of 7 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%.
- Each side has an average surface resistivity of 7.10 9 ohms at 50% relative humidity. At 15% relative humidity this average resistivity is 3.4.10 12 ohms and at 90% relative humidity it is 1.2.10 8 ohms.
- KODAK stiffness, porosity and air permeability are unchanged from the coated test paper.
- 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).
- Example 2 is used again, but the coated paper is not calendered so that it is matt.
- Example 2 It is characterized and tested as in Example 2.
- the surface resistivities are of the same order of magnitude as in Example 2.
- the coefficients of static and dynamic friction are 0.64 and 0.45 respectively.
