<P>PROBLEM TO BE SOLVED: To provide a solvent or solvent composition for pattern printing of a solar cell, an organic thin film transistor, electronic paper or an organic electroluminescence device, which ensures high solubility of a resin additive such as a binder resin and has low hygroscopicity. <P>SOLUTION: The solvent or solvent composition for pattern printing of the solar cell, the organic thin film transistor, the electronic paper or the organic electroluminescence device is a solvent composition which is used when an element pattern constituting the solar cell, the organic thin film transistor, the electronic paper or the organic electroluminescence device is formed by a printing method, and contains a compound in which one of two terminal alkyl groups of a dipropylene glycol dialkyl ether is a methyl group and the other is a 3-5C straight chain or branched chain alkyl group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
