COMPOSITION AND METHOD FOR PRINTING A PATTERNED RESIST LAYER

摘要

The invention relates to a composition for printing a patterned resist layer onto an underlying, preferably etchable layer comprising: a) an acid-functional resin that is soluble in alkaline medium and insoluble in acidic medium, having an acid number of at least 100mg KOH/g; b) a base solvent having a boiling point between 100 and 250°C; and c) a tackifying solvent having a boiling point between 200 and 350°C; provided that the boiling point of the tackifying solvent is higher than the boiling point of the base solvent. The invention further relates to a method for making a patterned layer, a pixel design, and an LCD display.
