Description of the Invention: [Technical Field of the Invention] The present invention relates to a solvent or a geo-coolant composition which is difficult and has excellent resin solubility and is used by me. ^ ^ 所 [Prior Art] The patterning of electronic components such as a wiring board or a display is conventionally formed by a so-called photolithography method. The photolithography method is a method in which a paste group is applied onto a substrate, and a fine pattern is exposed and baked, and an unnecessary portion is removed by etching to form a pattern. The problem of 蚀 而 而 S S S S S S S S S S S S S S S S S 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于In addition, it is limited by the device 3: it is difficult to form a pattern for a large-area substrate. Therefore, in recent years, the pattern forming method does not require a large skirt and the material is used efficiently. It is also easy to correspond to the JI ink of the large-area substrate. Method, screen printing method, letterpress printing method, offset printing method, Zhaozhi 4 ^ ",, gravure printing method, micro-contact printing method", nano-printing method, etc., can be used for printing paste. The solvent used in the composition is an example of a propylene glycol ether solvent such as an ethyl scaly or a di-n-butyl bond, which is used as a solvent. However, it is inconvenient to use because the glycol ether solvent is ecologically toxic. The problem (Non-Patent Document 1). On the other hand, for the propylene glycol ether solvent, the conventional form is a solvent; the alcohol dipropyl ether alcohol diethylene glycol didecyl ether or diethylene glycol A paste composition of a component such as a propylene ether diethylene ether or a dipropylene glycol di-caprol 201224073 cation battery is used as a solvent (Patent Document 1), and in Patent Document 2, a propylene glycol secondary burning riddle is used. Among It has been described that propylene glycol dibutyl ketone which is strongly lipophilic is used. In addition, in the paste composition for forming an element constituting an organic thin film transistor, an electronic paper, and a plasma display, propylene glycol dimethyl ether and propylene glycol diethyl phthalate are conventionally known. A propylene glycol dialkyl ether such as a hydroxy ether, a propylene glycol dipropyl ether or a propylene glycol dibutyl ether is used as a solvent (Patent Documents 3, 4, and 5) 〇 [Prior Art Document] [Patent Document] [Patent Document 1] International Japanese Laid-Open Patent Publication No. 2007-167834 (Patent Document 4) Japanese Patent Application Publication No. 2004-6191 No. 5] Unexamined Patent Publication No. 2007-3 14376 [Non-Patent Document] [Non-Patent Document 1] Concise Evaluation Document for International Chemical Substances N〇.41 Diethylene Glycol Dimethyl Ether (2002) [Invention Contents] [Problems to be Solved by the Invention] It is known that propylene glycol dialkyl ether has superior volatility, but in particular, propylene glycol dimethyl ether is highly hydrophilic and easily absorbs moisture, and is formed into a solar cell or an organic thin film. crystal When the solvent composition of several patterns of electronic paper or plasma display is used as a solvent, there will be a problem that the component is inferior to 201224073. On the other hand, propylene glycol dibutyl ether is highly lipophilic and low in suction. However, since the solubility of the adhesive resin such as ethyl cellulose or acryl resin contained in the paste composition is low, it is difficult to use it as a printing solution. Thus, the object of the present invention is to provide a resin addition of an adhesive resin. A solar cell, an organic thin film transistor, an electronic paper, or a solvent or a capacitor composition for pattern printing of a plasma display having high solubility and low hygroscopicity. Another object of the present invention is to provide a solar cell, an organic thin film transistor, a sub-paper, or a plasma display pattern comprising the pattern printing solvent or solvent composition of the solar cell organic thin film transistor, electronic paper, or plasma display. Use a paste composition. Further, another object of the present invention is to provide a pattern forming method for patterning using the solar cell, the organic thin film transistor, the electronic paper, or the paste composition for forming a plasma display. [Means for Solving the Problem] The present inventors have found that in order to solve the above problems, it is found that one terminal alkyl group of propylene glycol dialkyl ether is a mercapto group, and the other terminal alkyl group is linear or branched. The c3-5^ group of the chain-shaped alkyl group has an excellent solubility of the resin additive and a balance of hygroscopicity in forming a component pattern constituting a solar cell, an organic thin film transistor, an electronic paper or a plasma display. In this case, when the compound is used as a solvent, it is possible to impart an adhesive resin solubility to the formation of the element pattern by a printing method, and it is possible to form a device which is difficult to deteriorate by moisture absorption. The present invention has been made based on such findings.
