COEXTRUSION INK FOR IMPROVING DEFINITION OF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide ink that is used for forming a relatively fine line or structure having a relatively high aspect ratio of functional material such as a conductive material or ceramics.

SOLUTION: A coextrusion ink set includes: first ink substantially lack in yield stress and high viscosity; and either second ink or a sacrificial material substantially lack in yield stress and high viscosity. As a result of the local mixture of the first ink and either the second ink or the sacrificial material, a material having finite yield stress or high viscosity is formed in the interface of the first ink and either the second ink or the sacrificial material.
