반사-방지 특성을 나타내는 코팅된 물품이 제공된다. 예시적인 코팅된 입자는 기판 및 상기 기판의 적어도 하나의 표면에 도포된 반사-방지 코팅을 포함한다. 반사-방지 코팅 층은 하기를 포함하는 산성 졸-겔 조성물로부터 형성된다: (a) 테트라알콕시실란; (b) 알킬 트라이알콕시실란; (c) 실란 작용성 아크릴 중합체; (d) 무기 옥사이드 입자; (e) 무기산; (f) 물; 및 (g) 용매. 코팅된 물품은 상기 반사-방지 코팅 층의 적어도 하나의 표면에 도포된 최외각 오염-방지 코팅 층을 추가로 포함한다. Coated articles demonstrating anti-reflective properties are provided. Exemplary coated articles comprise a substrate and an anti-reflective coating layer applied to at least one surface of the substrate. The anti-reflective coating layer is formed from an acidic sol-gel composition comprising: (a) tetraalkoxysilane; (b) alkyl trialkoxysilane; (c) a silane-functional acrylic polymer; (d) inorganic oxide particles; (e) a mineral acid; (f) water; and (g) a solvent. The coated article optionally further comprises an outermost anti-fouling coating layer applied to at least one surface of the anti-reflective coating layer.
