DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to a substrate for printing a polymer electronic device. 5 [Prior Art] Background of the Invention The basis of polymer electronic devices is formed by organic polymers having conductive, semiconductive or insulating properties independent of their chemical structure. 10 Since the soluble polymer can be dissolved in a specific solvent, it is particularly advantageous to use a soluble polymer, and therefore, it can be applied to a continuous printing method as an electronic ink on a flexible substrate. Therefore, polymer electronic devices offer the possibility of cost-effective manufacturing of integrated circuits. At the same time, very high print quality has been taken into account. The decisive factor is not only the optical quality, but also the functionality. With printed electronics, many different components and products can be fabricated and found to be used as circuits in the fields of electrode engineering, digital technology and communications. For example, in the case mentioned, it is a “wisdom” label for manufacturing, logistics or trade. The most commonly used version of this application is the RHD (Radio Frequency Identification Mark). Polymer electronic devices are typically printed on a polyester film in several layers. In part, the paper substrate is used for cost reduction purposes. When using such substrates, different polymers and printing methods are used. The printing method is mainly based on known printing processes, such as letterpress printing, lithography, 5 200912091 lithography, and screen printing. They allow for high printing speeds but lack sufficient resolution. Insufficient resolution is the cause of electrical errors. The improved resolution at the most suitable printing speed is provided by ink jet printing. Ink jet printing processes are known for use in the manufacture of full color polymer light emitting diodes. 5 Films or papers currently used as substrates for polymer electronic devices are somewhat defective depending on the polymer form suitable for polymer electronic devices. When rolled up or unrolled in a film or printed in a machine, the film exhibits undesirable continuous properties. This has a negative impact on printing accuracy and results in electrical errors in the printed electronic device sample. Furthermore, depending on the form of the polymer to be printed, the adhesion of the polymer to the surface of the film is somewhat unsatisfactory. Although paper substrates are cost effective, they are not suitable for ink jet printing. Due to the open paper surface and high roughness, the polymer solution (electron ink) penetrates the paper too quickly, thus negatively affecting the print quality and becoming a form of apparently insufficient resolution and non-uniformity. Furthermore, the paper substrate has the characteristics of no barrier to moisture and dust, and is only conditionally suitable as a substrate for printing, moisture and dust sensitive electronic device structures. SUMMARY OF THE INVENTION 20 SUMMARY OF THE INVENTION A fundamental problem underlying the present invention is to provide a cost effective substrate for printing polymeric electronic devices that does not present the above disadvantages. This problem is solved by including at least a base paper having a resin layer on at least one side. 200912091 [Embodiment] For the purpose of the present invention, the meaning of the term "base paper" is considered, and it is understood that the paper is uncoated or surface sized.

Particularly preferred is a polyethylene mixture consisting of LDPE and HDPE, whereby the LD/HD content ratio is 9: 丨 to 丨: 9, especially 3: 7 to 7: 3. Furthermore, the synthetic resin layer may contain a white coloring material, similar to titanium dioxide, and other auxiliary materials, such as a fluorescent whitening agent, a coloring matter, and a dispersion of the synthetic resin layer on the front side and the back side of 200912091, respectively. It is equal to 5 to 50 g/m2, preferably 20 to 50 g/m2, or particularly preferably 3 to 50 g/m2. In another embodiment of the present invention, a layer containing a color ratio of 10:1 to 2:5 and a hydrophilic binder may be placed between the base paper and the resin layer. Film-forming starches, like heat-modified starches, especially corn starch or starch modified with propyl are suitable as adhesives. The coating containing the colorant and the hydrophilic binder can be directly placed on the front side or the back side of the base paper 10. It can be applied to the base paper in a single layer or in multiple layers. The coating compound can be applied on-line or off-line together with aggregates commonly used in all applications for papermaking, whereby the selected content is such that after drying, the maximum coating weight per layer is 20 g/m2, especially It is 8 to 17 g/m2, or 2 to 6 g/m2 according to a specific example. The 15 colorant may be selected from the group consisting of metal oxides, silicates, carbonates, sulfides, and sulfates. In particular, colorants similar to clay, talc, calcium carbonate and/or barium sulfate are also suitable. & In a specific embodiment of the present invention, a color mixture is used which is composed of calcium carbonate and clay, and the content ratio is preferably from 30:70 to 70:30. 2〇 Based on the form of the polymer electronic device and the desired characteristics to be applied, other functional layers can be applied to the base paper in accordance with the present invention. Part of the functional layer is a functional layer having electrical properties, which has electrical conductivity, electrical insulation or semi-electricity' and thus can affect the properties of the material. Other functional layers are, for example, antistatic, anti-curling layers, adhesion, anti-caking properties, and/or 200912091. These layers improve adhesion to other substrates. Other layers with waterproof or water vapor and oxygen barrier effects can also be applied. This functional layer can be placed on the front side and/or the back side of the substrate and/or base paper.

The Ra-value of the front side of the substrate and the Rz-value of the back side of the substrate are determined. The average roughness value Ra is the calculated mean value of all deviations from the center line of the defined reference distance and the thickness distribution curve. The Rz-value represents the average roughness depth of the surface structure' and is the average of the individual surface roughness measured from a continuous single measurement distance in the coarseness profile. 20 Imprint 彳 Ink Adhesion Test adhesion with the help of an adhesive tape test. For this purpose, the printed material is covered with a TESA® film. Finally, the film was removed and the amount of traces of the printing ink was visually inspected. In order to make the trace amount easier to detect, the printing ink is slightly dyed before printing. 14 200912091 As shown in Table 1, the conductivity of the substrates (1 and 2) according to the present invention is comparable to that of the polyimide (VI) which is generally used as a matrix. However, the polyester film exhibits poor running ability in the printing press, which negatively affects printability. The quality of the running ability can be quantified by the roughness distribution curve on the back side of the wire. Paper-based substrates (V2 and V3) are difficult to print due to the surface of the raw sugar, which lacks a barrier effect, especially in terms of liquid resistance, and their tendency to release paper fibers and other particles, and thus their use is not applicable. As the base of the composite electronic device. On the contrary, the base body according to the present invention is characterized by the characteristics required for the above object. 10 Table 1 Test Completion Example Conductivity Front Side Thickness Ra Back Side Roughness Rz Printing Ink Adhesion
