Abstract
The present invention provides inexpensively an article with a hard coat excellent in anti-staining property, lubricity, scratch resistance and abrasion resistance. The present invention also provides a method for forming the hard coat. A hard coat agent composition comprising an active energy ray-curable compound is applied onto a surface of an article () to be hard-coat-treated, thereby forming a hard coat agent composition layer, a surface material layer is formed by film-forming with a surface material comprising a fluorine-containing polyfunctional (meth)acrylate compound on the surface of the hard coat agent composition layer, and active energy rays are irradiated onto the formed hard coat agent composition layer and surface material layer so as to cure the both layers simultaneously, thereby forming a hard coat layer () contacting the surface of the article () and an anti-staining surface layer () contacting the surface of the hard coat layer ().
