Abstract
The present invention provides a novel method for preventing or reducing color degradation or color change of a substrate over time, and is characterized by arranging at least one positively-charged substance selected from the group consisting of (1) a positive ion; (2) a conductor or dielectric having a positive charge; and (3) a composite formed from a conductor and a dielectric or a semiconductor, on a surface of a substrate, and arranging an insulating organic or inorganic substance on the aforementioned positively-charged substance.
Claims8
