Aqueous coating composition and method
PURPOSE: To obtain a sheetlike sterilization treating agent having immediate and durable disinfecting effects by making specific Ag+-containing glass fine powder and glass fibers into a sheet. CONSTITUTION: Glass fine powder (e.g. one obtained by adding AgNO3 to glass components such as Na2O, SiO2, etc.) containing monovalent silver ion (Ag+), having preferably 0.5-200μm particle diameter and glass fibers (e.g. short fibers of alkali-containing silicate glass having 0.5-8.0μm average diameter) is made into a sheet to give the objective sheetlike sterilization treating agent.
