Patent number: 8597780Abstract: A hard coat film excellent in abrasion resistance and saponification resistance. A hard coat layer includes a cured product of a curable resin composition containing a reactive inorganic fine particle having an average particle diameter of 5 nm to 30 nm, and has a skin layer, wherein the reactive inorganic fine particles are localized, in its surface region being an interface and its vicinity on a side opposite to a transparent substrate film side of the hard coat layer. Alternatively, the reactive inorganic fine particle has an average particle diameter of 30 nm to 100 nm, and has density distribution in a thickness direction of the hard coat layer lowest at an interface on a side opposite to a transparent substrate film side of the hard coat layer while the density is highest at an interface and its vicinity on the transparent substrate film side of the hard coat layer.Type: GrantFiled: August 8, 2008Date of Patent: December 3, 2013Assignee: Dai Nippon Printing Co., Ltd.Inventors: Emi Shimano, Toshio Yoshihara
