Title:
ＩＴＯ導電膜形成用組成物及びＩＴＯ導電膜
Document Type and Number:
Japanese Patent JP6530644
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a composition for forming an ITO conductive film which can suppress the increase of surface resistivity of an ITO conductive film under high temperature and high humidity and irradiation with ultraviolet rays, is excellent in adhesiveness to a substrate, and has good conductivity, transparency and light resistance, and to provide an ITO conductive film.SOLUTION: There is provided a composition which contains ITO particles, a binder resin and an organic solvent, contains 3-45 mass% of the ITO particles in the composition, and 10-52 mass% of the components other than the ITO particles in a solid matter of the composition, where the ITO particles have a specific surface area of 42-65 m/g by a BET method and an L value of 36 or less, and the binder resin contains ethyl cellulose and a terpene phenol resin having a softening point of 130-160°C. The ITO conductive film is formed by uniformly dispersing ITO particles having the above described predetermined specific surface area by the BET method and the above described predetermined L value into a terpene phenol resin having the above described softening point, and contains 48-90 mass% of the ITO particles in the film and 10-52 mass% of the components other than the ITO particles in the film.SELECTED DRAWING: None
