Title:
INK COMPOSITION AND A PRINTING METHOD AND PATTERN FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/032795
Kind Code:
A1
Abstract:
There are problems in printing methods that include a step in which a base to which ink has already been applied to the entire surface thereof is brought in contact with another base, and ink is separated using the difference between the adhesions of the respective bases and the differences in adhesion within the base surfaces, wherein, with respect to intricate patterns sought in the formation of electronic parts, it is crucial to prevent webbing of the ink, while in methods that use an ink composition of uniform viscosity throughout, the ink does not selectively separate at the shear face during transfer, and only a defective version of the desired form is produced in the transferred pattern. Disclosed is an ink composition and printing method that uses the same, which are characterized by containing at least a fine particulate, a linker that possesses multiple functional groups that interact with said fine particulate, and a solvent, by forming a structure in which said particulates are linked to one another by the linker, and when shearing force is exerted, by serving the links at the interface between the fine particulate and the linker in areas where said shearing force is exerted.
