NON-AQUEOUS INK FOR INK JET AND METHOD FOR APPLYING INK

摘要

PURPOSE: Ink for non-aqueous inkjet is provided to obtain desired pattern layers since little crawling or moisture diffusion on a flat substrate without surface treatment after jetting. CONSTITUTION: Ink for non-aqueous inkjet contains surfactants(B). The concentration of the surfactant(B) is 0.00001 weight% or more and a critical micelle concentration or less. A method for applying the ink comprises a step for applying the ink for non-aqueous inkjet through an ink jet application method. A method for forming a polyimide film comprises the steps of: applying the non-aqueous inkjet ink on a substrate according to an ink-jet application method to form a film; and heating the film to form a polyimide film.
