PROBLEM TO BE SOLVED: To provide articles exhibiting excellent abrasion resistance.SOLUTION: Coated articles are provided comprising: (a) a substrate; (b) a porous sol-gel layer superimposed on at least one surface of the substrate, comprising a hydrolyzed tetraalkoxysilane; and (c) a sealant layer superimposed on at least one surface of the porous sol-gel layer and comprising an alkyltrihalosilane. The coated articles demonstrate superior abrasion resistance due to a glass-like layer formed from the combination of the porous sol-gel layer and sealant layer. The present invention relates to coated articles having abrasion resistant, glass-like coatings.SELECTED DRAWING: None 【課題】優れた耐摩耗性を示す物品を提供すること【解決手段】（ａ）基材；（ｂ）前記基材の少なくとも一つの表面に重ね合わされた、加水分解されたテトラアルコキシシランを含む多孔性ゾル−ゲル層；および（ｃ）前記多孔性ゾル−ゲル層の少なくとも一つの表面に重ね合わされた、アルキルトリハロシランを含むシーラント層を含む被覆物品が提供される。この被覆物品は、前記多孔性ゾル−ゲル層と前記シーラント層との組み合わせから形成されるガラス様層により、優れた耐摩耗性を示す。本発明は、耐摩耗性でガラス様の被覆を有する被覆物品に関する。【選択図】なし
