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

摘要

An object of the present invention is to provide a coat layer capable of suppressing adhesion of contaminants even when the weather is clear or when it is dry, in addition to having excellent water washability. The present invention relates to an aqueous antifouling coating composition obtained by mixing a siloxane oligomer represented by the following general formula (1), a water component, an antistatic agent, and silica fine particles, By weight based on the total weight of the composition. Further, the present invention relates to an antifouling coat layer, a laminate, and a solar cell module that include an aqueous antifouling coating agent. In the general formula (1), R ¹ to R ³ each independently represent an organic group having 1 to 6 carbon atoms, and R ⁴ represents an alkyl group having 1 to 6 carbon atoms. In addition, n represents an integer of 2 to 20.
