Definitions
- the present invention relates to ultra-opaque coated sheets and their manufacturing process.
- Ultra-opaque coated sheets are commonly used in various applications for which they must be able to be printed and where it is imperative that the opacity of said sheets is much greater than that of conventional coated sheets of comparable weight per square meter.
- ultra-opaque sheets which are produced by coating, traditionally by means of air knife, drag blade or rotary bar couplers, of at least one of the two faces of a multijet paper support, preferably a trijet where the central jet of gray paper composition provides ultra-opacity by absorption of light, and is framed by two jets of white paper composition such that all of each white jet supporting one or more white layers gives the ultra-opaque sheet has a white and homogeneous visual appearance.
- a drawback of this technique is the difficult and expensive implementation of a multi-jet machine, in particular for the manufacture of papers with low grammage.
- Ultra-opaque sheets are also known which are produced by at least two jets of white coated paper laminated with a black glue and where there too the ultra-opacity is provided by the absorption of light due to the black coloring, while maintaining a white and homogeneous visual appearance.
- This technique has the drawback of using laminating, a step which is often difficult to carry out, due to the choice and the quantity of glue to be used, which does not allow high manufacturing speeds and which can sometimes cause assembly faults between the paper jets.
- One of the aims of the invention is therefore to provide ultra-opaque sheets which can be manufactured at low cost, at high speeds and which do not have the manufacturing constraints of the prior art.
- Another object of the invention is to provide ultra-opaque sheets having a very good surface condition.
- the Applicant proposes in particular to use the most widespread production equipment, in particular single-jet paper machines, and to reduce the number of manufacturing steps, in particular the laminating step.
- the Applicant endeavored to provide an opacifying base support from a single jet of colored material to which one or more white layers are applied on at least one of the faces.
- the colored support is intended in this case to screen the passage of light, an imperative condition for obtaining the desired opacity.
- the intensity and the nuance of the color of the support depend on the final application and on the ultra-opacity sought by absorption of the light: preferably the color of the basic support is more or less gray, more or less black.
- the colored monojet is therefore coated, depending on the final applications on one or two sides, so as to provide a white and homogeneous visual appearance, as well as good printability.
- the Applicant has taken advantage of modern coating methods in the paper industry, to guarantee uniformity in the coating, a condition necessary for obtaining good opacity and good printing results in the end.
- the curtain coating process is a pre-dosed coating method, used in the photographic industry for over 20 years. This technology was developed for photographic films, which require the deposition of many different layers, generally between 8 and 10, with severe constraints both in terms of the surface state and the thickness of the layers applied.
- the curtain coating process is based on free flow on a surface from a coating head located above the surface to be coated at a height varying between 10 and 25 cm.
- the coating head is defined according to the properties of the coating fluid, so as to obtain the most uniform thickness of coating film possible in the machine direction.
- Two types of coating heads are generally used: slotted heads and sliding surface heads, as shown in FIGS. 1 and 2.
- One of the advantages of curtain coating is the possibility of applying two or more layers simultaneously.
- Slot heads are in practice limited to 2 or 3 layers maximum due to their configuration, while the maximum number of layers deposited simultaneously in a sliding surface head can exceed 10. Another advantage is the absence of contact between the coating head and the support, unlike the blade coating in particular.
- the subject of the invention is therefore an ultra opaque coated sheet consisting of a colored support produced from a monojet of material, said support being coated on at least one of its faces with one or more white or light pigmented layers.
- pigmented layers is meant the compositions (mainly comprising pigments and binders) commonly used for coated printing-writing papers. Their number, their exact composition, their weight per square meter depends on the final application of the ultra-opaque sheet.
- the sheet has an ultra-opacity index greater than 92, and advantageously greater than or equal to 94 in the case where its grammage is less than 300 g / m 2 and an index d '' ultra-opacity greater than 94, and advantageously greater than or equal to 98 in the case where its grammage is greater than or equal to 300 g / m 2 .
- the ultra-opacity index will be explained later in the description of the invention.
- the sheet has a whiteness measured according to ISO 11475 standard greater than 75, and preferably greater than or equal to 78.
- the monojet of material is a paper based on cellulose fibers.
- the monojet is a colored plastic film or a plastic film with an opacifying colored precoat.
- the weight per square meter of the paper or plastic monojet is directly dependent on the application. It is between 50 and 500 g / m 2 .
- the subject of the invention is also a method of manufacturing a sheet defined above, in which a colored support is first produced from a monojet of material, support which is then coated on at least one of its faces with one or more white pigmented layers.
- the deposition of the white pigmented layer or layers is carried out by means of a curtain coating head.
- the opacifying coloring is obtained by incorporating opacifying pigments into the mass of a paper jet.
- the opacifying coloring is obtained by depositing on the surface of a paper jet a pre-layer of opacifying pigments either by means of a size press or by means of a coating device. , in particular a curtain coating head, and preferably simultaneously and using the same curtain coating head as during the coating of the white pigmented layer (s).
- the monojet of material is a colored plastic film or a plastic film covered with an opacifying colored precoat.
- the coloring material used is carbon black.
- the invention also relates to the ultra-opaque playing card obtained by the previously defined method or comprising as a base an ultra-opaque coated sheet previously defined.
- the invention can be extended to the preparation of lightly colored or pastel ultra-opaque sheets for which the modifications to be made relate only to the coating pigment and not on the essential elements of the invention.
- a light source incident consists of an incandescent filament lamp, transparent glass bulb, marketed by Philips under the reference 60W-220N.
- the coated sheet is placed both between and in contact, a) on the light source side, with a diaphragm with a diameter of 12 millimeters and b) on the opposite side, with the sensor with a diameter of 20 millimeters a luxmeter device marketed by Gossen under the reference Mavolux Digital.
- the distance between the luxmeter sensor centered on the diaphragm and the light source is adjusted beforehand so that without the coated sheet, the value read in incident direct light is 14000 lux and the value L in lux of light transmitted is noted. of the coated sheet.
- the opacity of this sheet can then be quantified by an “ultra-opacity index” defined by the formula:
- Ultra-opacity index 100 x (1- L / 14000)
- traditional white coated papers that is to say non-opaque papers have, according to this method, indices of ultra-opacity of the order of 77 for a paper of 130 grams per square meter, and of the order of 94 for a paper of 300 grams per square meter.
- the homogeneity of the visual appearance of the surface of the different leaves is evaluated using the Khéops device sold by Techpap. This device equipped with a CCD camera performs an image analysis of the differences in color and luminosity of the surface and gives an overall value which is lower the greater the homogeneity.
- the whiteness of the surface of the various sheets is measured according to ISO standard 11475 in the absence of ultraviolet light.
- An ultra-opaque sheet according to the prior art la consists of a bijet paper machine support paper, one of which is a gray paper composition to provide opacity and the other of which is a white paper composition; this bijet, on the external face of the white jet, is coated by steel blade process with a white pigmented layer mixture of 90% calcium carbonate and 10% styrene butadiene latex to give said sheet the state of surface necessary for printing-writing use on the coated side.
- An ultra-opaque sheet according to the invention lb of weight per square meter similar to the sheet la, is produced from a single-ply paper of weight per square meter equal to 100 g / m 2 of gray color whose opacifying coloring is brought here by the curtain coating process in the form of a prelayer on each face of
- said layer comprising in dry 0.05 part of black carbon for 100 parts of a mixture of 90% calcium carbonate and 10% styrene butadiene latex.
- This colored monojet is then coated, still by curtain coating process, on each of its two faces of 10 grams per square meter of a white pigmented layer identical to that used in example la.
- Another ultra-opaque sheet 1c is produced by coating with a steel blade the colored monojet of the sheet lb, with 10 grams per square meter on each side of the same white pigmented print-write layer as the sheet lb.
- the sheet 1b according to the invention although of slightly lower weight per square meter, is both more ultra-opaque, whiter and more homogeneous in surface finish than the sheet 1a of the prior art made from a more complex industrial process (bijet).
- An ultra-opaque sheet according to the prior art 2a consists of two jets of white coated paper laminated with a black glue representing in dry 0.24 grams per square meter of carbon black.
- An ultra opaque sheet according to the invention 2b of weight per square meter identical to sheet 2a, is produced from a single-ply paper of weight per square meter 240 grams of gray-black color where the opacifying coloring is provided as in example lb by a precoat on each side of 5 grams per square meter, said layer comprising in dry 0.5 part of carbon black for 100 parts of a mixture identical to that used in example lb.
- This colored monojet is then coated, still by curtain coating process, on each of its two faces of 30 grams per square meter of a white pigmented layer identical to that used in example lb.
- the sheet 2b according to the invention produced without the additional counter-coating step, has the same level of surface quality (whiteness, homogeneity) as sheet 2a of the prior art.
