CONDUCTIVE INK FOR REVERSE PRINTING, PROCESS FOR PRODUCING THIN-FILM TRANSISTOR, AND THIN-FILM TRANSISTOR PRODUCED BY SAID PROCESS

摘要

Provided is a conductive ink which is for use in letterpress reverse printing and which exhibits a wider permissible time range for transferring the whole of a pattern formed on a blanket to a substrate. Specifically provided is a conductive ink which is for use in letterpress reverse printing and which can form a conductive pattern through the fusion-bonding among conductive particles, said conductive ink being characterized by comprising: conductive particles which have a volume-mean particle diameter (Mv) of 2 to 250nm; and a liquid medium which comprises a water-containing organic solvent and contains a fluorine-based surface energy regulator and/or a silicone-based surface energy regulator and in which the conductive particles are dispersed. Also provided are: a process for producing a thin-film transistor, characterized by including a step for forming a pattern-wise coating of the conductive ink on a substrate by a letterpress reverse printing method, and then fusion-bonding the conductive particles contained in the pattern-wise coating to form a conductive pattern; and a thin-film transistor.
