<p><P>PROBLEM TO BE SOLVED: To provide a coating composition capable of forming a coating film excellent in antifouling performance without impairing color tone, texture, and characteristics of a porous base material, and to provide a production method therefor. <P>SOLUTION: This coating composition includes 10 mass% or less of silica fine particles, 5 mass% or less of resin fine particles, 0.5 mmol/L or less of divalent or more metal ions, and water. This production method for a coating composition containing 10 mass% or less of silica fine particles, 5 mass% or less of resin fine particles, 0.5 mmol/L or less of divalent or more metal ions and water includes: dispersing silica fine particles and resin fine particles in water to prepare a dispersion; and adding an aqueous solution of divalent or more metal ions to the dispersion. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
