Solvent or solvent composition for printing

Abstract

The invention provides a solvent or solvent composition which is used in printing ink of electronic component patterns formed by a printing method. The solvent or solvent composition gives excellent stencil misplacing property at printing and excellent pattern maintenance and quick-drying property at high temperature and dry to the printing ink. The solvent or solvent composition for printing the electronic component patterns is used for the electronic component patterns through the printing method, and contains at least more than 10 % by weight of 1,2,5,6-tetrahydro benzyl alcohol in the total weight (100 %) of the solvent or solvent composition. The printing method is preferably selected from at least one of an inkjet method, a screen printing method, a letterpress printing method, an offset printing method, a gravure printing method, a micro-contact printing method and a nano-imprinting method.

Description

technical field [0001] The present invention relates to a solvent or a solvent composition contained in a paste composition, ink, etc. for forming an electronic component pattern by a printing method, which imparts printing to the paste composition, ink, etc. Excellent release property when drying, excellent pattern retention when drying at high temperature and quick drying. Background technique [0002] Conventionally, patterns of electronic components such as wiring boards and displays are often formed by a method called photolithography. The photolithography method is a method of applying a photosensitive substance on a substrate, exposing a fine pattern, baking, and removing unnecessary portions by etching to form a pattern. However, generally, an etching waste liquid treatment facility is required, so the apparatus itself becomes large, requiring a huge investment in equipment, and there is a problem of poor productivity due to poor material use efficiency and many man...

AI Technical Summary

Problems solved by technology

However, terpineol has a problem that the viscosity of terpineol is too high at room temperature, so that the release property of the ink is reduced, and the viscosity of terpineol is too low at high temperature, so that there is a problem of reducing the pattern retention of the ink.

Dihydroterpinyl acetate has a low viscosity, so it can impart excellent release properties to the ink, but it has the same problem as terpineol that reduces the pattern retention of the ink at high temperatures

In addition, terpineol and dihydroterpineol acetate have high vapor pressure at drying temperature, so there are disadvantages such as slow evaporation rate and time-consuming drying (Non-Patent Document 1)

[0006] That is, in the ink used in the printing method, when terpineol or dihydroterpineol acetate is used as a solvent, there is a fear of occurrence of Problems such as short circuits and time-consuming drying
