An article with silica coating formed, wherein although the coating is one produced by a sol gel process and having a thickness as large as over 300 nm, the coating is not detached from the base material after Taber's abrasion resistance test prescribed in Japanese Industrial Standards (JIS) R 3212. This coating can be formed by an improved sol gel process, namely, a sol gel process comprising employing a coating liquid wherein the concentration of silicon alkoxide in terms of SiO2 exceeds 3 mass% and is lower than 9 mass% and wherein the mass molarity of proton is in the range of 0.001 to 0.2 mol/kg and the molar amount of water in the range of 4 times to 10 times the total molar amount of silicon atoms and further comprising heating the base material at temperature higher than 100 DEG C. |
