Disclosed is a solvent for printing which comprises a first solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol and mixtures thereof, and a second solvent selected from the group consisting of propylene glycol monomethyl ether acetate (PGMEA), propylene glycol monomethyl ether (PGME), isopropanol, butyl acetate, ethyl-3-ethoxypropionate and mixtures thereof. Further disclosed are a pattern composition for printing comprising the solvent for printing, and a patterning method using the composition. The use of the solvent for printing enables formation of an accurate pattern.

SUMMARY OF THE INVENTION
[0026] Accordingly, the present invention is directed to a solvent composition for printing, a pattern composition for printing comprising the solvent composition, and a patterning method using the pattern composition that substantially obviates one or more problems due to limitations and disadvantages of the related art.
[0027] Additional advantages and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
[0028] To achieve these and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a solvent composition for printing comprises a first solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol and mixtures thereof, and a second solvent selected from the group consisting of propylene glycol monomethyl ether acetate (PGMEA), propylene glycol monomethyl ether (PGME), isopropanol, butyl acetate, ethyl-3-ethoxypropionate and mixtures thereof.
[0029] In another aspect of the present invention, a pattern composition for printing comprises a pattern material, a solvent composition, a dispersant, and a binder. The solvent composition comprises a first solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol, and mixtures thereof, and a second solvent selected from the group consisting of propylene glycol monomethyl ether acetate (PGMEA), propylene glycol monomethyl ether (PGME), isopropanol, butyl acetate, ethyl-3-ethoxypropionate, and mixtures thereof.
[0030] In yet another aspect of the present invention, a patterning method comprises the steps of applying the pattern composition for printing on a blanket attached to a printing roll to form a pattern having a predetermined shape, and rotating the printing roll on a substrate to transfer the pattern to the substrate.
[0031] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
