HYDROPHILIC FILM AND PRODUCTION PROCESS THEREFOR, LAMINATE, PROTECTIVE MATERIAL FOR SURVEILLANCE CAMERA, AND SURVEILLANCE CAMERA

摘要

A hydrophilic film comprising a siloxane binder and silica particles and having a surface which has a surface area difference ΔS and a surface roughness Ra that satisfy the following relationship 1; a process for producing the hydrophilic film; a laminate; a protective material for surveillance cameras; and a surveillance camera.ΔS≤0.5Ra relationship 1In relationship 1, ΔS is the percentage determined with the following equation 2.ΔS=[(S_X-S₀)/S₀]×100 equation 2In equation 2, S₀ represents the projected area of the hydrophilic film viewed from the perpendicular direction, and S_X represents the actual surface area of the hydrophilic film having the projected area expressed by S₀.
