WATER-BASED ANTI-SOILING AGENT, ANTI-SOILING LAYER, LAYERED BODY, AND SOLAR BATTERY MODULE

摘要

An object of the invention is to provide a coating layer that can suppress the attachment of contaminants at the time of fine weather or drying, in addition to the ability to be cleaned by washing with water. The invention relates to a water-based anti-soiling agent including, in a mixed manner, a siloxane oligomer expressed by General Formula (1) below; a water component; an antistatic agent; and silica fine particles, in which a component exhibiting surface activity is 0.01% by mass or greater is included in the water-based anti-soiling agent, and in General Formula (1), each of R¹ to R³ independently represents an organic group having 1 to 6 carbon atoms, R⁴ represents an alkyl group having 1 to 6 carbon atoms, and n represents an integer of 2 to 20.
