Definitions

  • the inkjet printing technique has been a definite success.
  • the detailed study of the characters obtained by this technique shows the existence of a certain number of defects due to the non-adaptation of the sheet on which the recording is made, to the particularities of the inkjet technique.
  • US Patents 4,269,891, US 4,461,174 recommend the use of absorbent fillers comprising, in particular, silica, diatoms, zeolite, synthetic or natural silicates.
  • Japanese patent J 56 148 582 and the following claims the use of coating fillers of the same kind and, in particular, an amorphous silica micropowder with different synthetic binders.
  • US Patent 4,460,637 claims a particular distribution of pore diameters in the layers of paper for inkjet printing, consisting of absorbent fillers.
  • the support can act on the support by modifying its absorbency, its structure, the shape of its constituent elements, its smoothness, etc., which requires a precise definition of the quality of the support for each particular case.
  • microcracks can be reduced by increasing the rate of binder, but we then come up against problems such as the difficulty of drying, the increase in the cost of the composition and the lowering of the color densities. It is also possible to reduce the microcracks by decreasing the temperature and the drying speed, but this leads to significant economic limitations. It is also possible to sleep in two or more passes, which is the subject of US Pat . No. 4,440,827 , but again the economic cost is considerable.
  • the object of the present invention is to eliminate the defects mentioned above without supporting the harmful consequences, the difficulties and the costs which result from the application of the methods described.
  • Boric acid and its derivatives have been frequently used for various industrial applications, among which it is possible to cite abrasives, antifreezes, cements and plasters, glues, enamels, fireproofing, metallurgy, products pharmaceutical and cosmetic, tanneries, glassware, stationery.
  • patent JP-A-87 089/85 which describes a sheet for ink jet recording comprising an oil absorption pigment, a coagulating agent for this pigment consisting of a magnesium compound, and a binder.
  • the sheet thus obtained has improved properties relating to the drying speed.
  • the sheet thus obtained is however not likely to lead to an enlarged shape of the points, while retaining a good quality of shape and uniformity of said points.
  • the object of the present invention is to produce a coated printing sheet usable by the inkjet technique, which can be implemented by known papermaking techniques and which eliminate the defects noted in the results obtained by use of the inkjet technique on the printing sheets described to date.
  • Figs. 1 to 6 are representations of results obtained with certain known printers using, according to two examples of implementation, an ordinary inkjet printing paper sold, a specific paper and a paper according to the invention.
  • Figs. 7 to 9 show one of the advantages provided by a paper according to the invention.
  • the sheet according to the invention for inkjet printing consisting of a support sheet, one face of which is surmounted by a layer, said layer being produced by coating of a sauce on this support, is characterized in that it comprises, in its layer, a polyhydroxylated polymeric binder comprising hydroxyl groups in the cis position, said binder having been gelled or coagulated with boric acid and / or its derivatives when lying down, and a filler having absorbing power.
  • the polyhydroxylated polymeric binder whose hydroxyl groups are in the cis position is preferably of the polyvinyl alcohol or polyvinyl alcohol copolymer type.
  • the products which can be used are, for example, described in the book "Polyvinyl alcohol properties and applications" published by CA FINCH and published by J. WILEY and sons.
  • a polyvinyl alcohol the characteristics of which (degree of hydrolysis and degree of polymerization) may be suitably chosen as a function, in particular, of the process for preparing the sheet used.
  • the amount of gelling agent (or coagulant) used can vary depending on the mode of use of this agent.
  • agent When said agent is deposited on the support of the sheet, preferably 0.05 to 2 g / m2 of boric acid and its derivatives will be used.
  • the filler having a high absorbency used in the invention, is a material known for its large specific surface and can be chosen from the following products: silica, various silicates, zeolites, calcined kaolins, diatoms, barium sulphate, d hydroxides. aluminum, melamine-formaldehyde or urea-formaldehyde pigments.
  • the proportions between the two main constituents of this coating layer can vary within a wide range, but are very generally between 10 and 100% by weight of binder relative to the filler.
  • the coating layer may contain additives, conventionally used in such layers, such as, for example, defoamers, surfactants, brighteners, etc.
  • the layer weight is approximately 0.5 to 20 g. / m2.
  • the present invention also relates to methods for producing the sheets according to the invention.
  • Any support will be used on which a coating sauce will be deposited.
  • the support used may or may not be of a cellulosic nature and may have been obtained by paper or not. We can use paper, cardboard, synthetic film, non-woven support ... The nature and physical properties of said support are not critical and depend mainly on the type of finished product sought.
  • the gelling agent will be provided with said support, either by incorporating said agent into the support itself, or by depositing said agent on the surface to receive the coating sauce.
  • the coating sauce comprising the polyhydroxylated polymeric binder will simply be deposited on the support comprising said gelling agent and the charge and gelling of said binder will occur during the coating operation.
  • the gelling agent will be incorporated into the coating sauce, but it will be necessary, beforehand, to deactivate (temporarily) said gelling agent and to reactivate it at the time of coating.
  • the inactivated gelling agent can be boric acid which, if it causes an increase in the viscosity of the aqueous medium containing polyvinyl alcohol, does not cause total gelling of this alcohol. In this case, gelation occurs by contact between the coating preparation and the support, the pH of which should preferably be close to neutral.
  • the coating of the support is carried out by conventional coating methods with a roller (size-press, engraved roller, bar, reverse roll, etc.) or with a blade (air knife, trailing blade, etc.).
  • a smooth and flawless layer is thus obtained, the thickness variations of which between distant points of less than 500 microns in the direction of the plane of the sheet, are insensitive and have no measurable effect.
  • the layer is smoother, has no cracks and is better individualized with respect to the support, the interpenetration area being reduced.
  • the invention therefore allows, more easily and cheaply, the optimal adaptation of the quality of the recording sheet to the type of printer for which it is intended.
  • the solidity of the layer and its bond to the support were measured by the speed at which the layer begins to tear off by printing a Lorilleux 3802 ink on an IGT Ait 2 device.
  • the tearing speeds and the layer weights are the following :
  • the two papers were printed with a Diablo inkjet printer (SHARP I0.0700 technology), as well as a commercial paper c) presented as a reference for such a printer. These three papers were printed with the same black SCHARP ink.
  • Figs. 7 to 9 correspond to photographs produced according to the same operating conditions as above, from papers treated in accordance with the invention and printed by a SIEMENS PT 88 printer with black SIEMENS ink. Examination of these figures shows that it is possible to widen the range of point diameters that can be obtained, while retaining the qualities of shape and uniformity highlighted above. Examination of these figures shows that it is possible to obtain points of very good quality whose diameters are in a ratio of 1 to 3 for the same volume of ink, by acting on certain parameters of the layer. paper processing, such as specific surface, nature and rate of binders, thickness, humidity.
