Definitions
- the invention relates to a transparent paper and a method for Production of a transparent paper.
- Transparent papers consist of densely packed, highly ground Fibers, such as in Wolfgang Walenski's "Paper Book", Verlagp + Hydr, 1994 and 1999, Itzehoe, Germany on page 122 explained. They are, for example, from JP 03 216307 A, from WO 85 03316 A and known from US 3,839,144.
- JP 03 uses 216307 A a glassine enriched with fillers, i.e. highly satined Tracing paper to form prepreg.
- WO 85 03316 A and the US 3,839,144 damage with paper properties.
- WO 85 03316 A strikes WO 85 03316 A before, on conventional paper a layer of high apply ground fibers to improve the surface properties affect, however, making a paper that is transparent in its entirety cannot be provided.
- US 3,839,144 proposes a mixture of highly ground fibers and other fibers use to influence the paper properties in such a way that received a less densely packed paper with good eraser properties becomes. On the other hand, such papers lose their transparent ones Characteristics.
- backlit areas that are colored, graphical or otherwise Are designed to provide, so far one is so far on the Use of plastic films, usually referred to as "backlight films", instructed since all known tracing papers go through different phases possessing basic structure, which when shining through with the actual color or graphic representation mixed and on this Way a brilliant and sharp reproduction of the on the Transparent paper located representation prevented.
- the object of the invention is a transparency To provide, which is suitable as a backlit medium.
- a further object of the invention is to provide a method for To specify the manufacture of such a transparent paper.
- the object is achieved by a transparent paper according to claim 1.
- the invention is based on the surprising finding that the Transparent layer fillers can be added without the Significantly affect transparency, the term "transparent” here in the sense of "translucent” (not necessarily transparent) is used.
- transparent here in the sense of "translucent” (not necessarily transparent) is used.
- the use of fillers makes it possible for the first time otherwise usually visible with tracing paper Conceal irregularities because the fillers block the light passing through reflect diffusely, which leads to a desired reduction in Transparency and especially to a homogeneous frosted glass Review leads.
- the fibers contain the transparent layer of sulfate pulp fibers, especially long-fiber ones Sulphate pulp fibers and fillers with a total weight of 1 to 6 % of the total weight of the fibers contained in the transparent layer.
- Silicates in particular silicates from the group of precipitated calcium, aluminum, calcium aluminum and sodium aluminum silicates as well as a lead silicate are particularly proven.
- the use of these fillers results in two phases in paper, with the Interfaces of the phases to a refraction of the light and due to the Silicate structure and the size of the fillers for a diffuse scattering of the Transmitted light comes so that the tracing paper when illuminated by "milky" appears evenly behind.
- the fillers act like water-insoluble, compared to the other ingredients of Transparent layer with chemically neutral behavior. with these none Bonds incoming pigments of the smallest particle size and are in the Usually white. However, in order to achieve special effects colored pigments are used. It has proven to be particularly useful proven when the grain size of the pigments is between 0.5 and 2.0 ⁇ m.
- the refractive index of the pigments is approximately in the order of magnitude of Refractive index of the fibers of the transparent layer, that is Usually between 1.5 and 1.6, with cellulose one Refractive index of 1.53 and the pigments from the aforementioned Materials have a refractive index of 1.56 to 1.57, and is Silicate concentration based on the pulp mass use about 2 to 5%, so you get a transparent paper with a transparency of 30 to 40%, which is excellent for use in light boxes and the like suitable.
- the paper weight of the transparent layer should be in the range from 100 to 250 g / m 2 , preferably between approximately 150 and 200 g / m 2 , so that the paper is stable enough on the one hand, but on the other hand it is also elastic enough to be processed, for example, by means of commercially available ink steel printers and plotters.
- a Ink receiving layer may be provided by the transparency layer will be carried. This makes it possible for the applied liquid to run Color, especially when printing with inkjet printers reduce or avoid entirely. It can also be a strong one Waviness of the transparency layer when absorbing moisture avoid. In this way, a printed image with sharp contours can be created provide, since the colors are less blurred, under the term "Color" is understood here as black.
- the Ink receiving layer for receiving inks from inkjet printers be trained. But it can also be used for screen printing or airbrush processes be interpreted.
- an ink receiving layer which is also called a color receiving layer could refer to, for example, a mixture of partially saponified Polyvinyl alcohol and / or polyvinyl pyrrolidone, especially in the ratio of 9: 1, especially proven.
- a borax-containing binder has proven to be useful.
- Transparent layer on a complex formation between the Polyvinyl alcohol and the borax which is in the acidic pH range Forms polyvinyl alcohol-boric acid monodiol complex.
- Polyvalent alcohols are suitable for fixing the polyvinyl alcohol Metal ions from IV. To VI. Main group of the periodic table in particular. Even low concentrations lead to gelation of the Polyvinyl alcohol.
- such an ink receiving layer is also independent of the other properties of the transparency layer or Transparent paper for printing on paper layers with extreme high fiber packs is suitable.
- such a layer can also be used advantageously with conventional transparent papers.
- the ink receiving layer later load-bearing paper layer with tightly packed fibers from a high ground pulp mass with the addition of water-insoluble Pigments with a proportion between 2 and 5 percent by weight based on the pulp is made.
- partially saponified Polyvinyl alcohol and polyvinyl pyrrolidone are an ink receiving fluid mixed, which is finally added to the transparent layer a borax-containing binder is applied.
- the polymer solution which acts as an ink receiving layer, can also be used usual coating processes such as, for example, doctor blades, blades and other common coating processes on the tracing paper be applied.
- the machine can be used to coat the transparent layer with the Ink receiving layer coating speeds up to 100 m / min can be reached.
- the tracing paper consists of at least two layers, namely a transparent layer and an ink or Color absorption layer is there and that the tracing paper transparency reducing fillers are added.
