HYDROPHILIC COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To prepare a hydrophilic coating material forming a water film and preventing water droplets from attaching when the coating film prepared is soaked with water by adding a lactate to an acrylic resin-based aqueous emulsion having surface activity. SOLUTION: This hydrophilic coating material is prepared by adding a lactate (e.g. calcium lactate) to an acrylic resin-based aqueous emulsion having surface activity and obtained by the copolymerization of acrylate with methacrylate. It is pref. to add ethanol to the coating material.
