摘要： A curable resin composition for a hard coat layer capable of forming a hard coat layer having high hardness even with thin thickness and/or excellent in abrasion resistance and hardness, and a hard coat film using the curable resin composition are provided. A hard coat film in which a hard coat layer is provided on one side of a transparent substrate film, wherein the hard coat layer comprises a matrix in a crosslinked state and an aggregate in which 3 to 100 silica fine particles having an average primary particle diameter of 1 to 100 nm are aggregated, and wherein the aggregate is cross-linked to the matrix, and an irregularly shaped silica fine particle constituted with 3 to 20 silica fine particles having an average primary particle diameter of 1 to 100 nm connected to each other by inorganic chemical bonding is contained as a part of the aggregates. The hard coat layer further contains a silica fine particle preferably.

摘要： The present invention is to provide an optical sheet having excellent abrasion resistance and hardness, and a method for producing the same. The object of the present invention was accomplished by an optical sheet in which a hard coat layer is provided on one surface of a substrate, wherein the hard coat layer comprises a cured product of a curable resin composition for a hard coat layer, which composition comprising reactive, irregularly shaped silica fine particles and a binder component, and wherein at least part of the irregularly shaped silica fine particles have a specific three-dimensional configuration and are present on an interface on the side opposite to the substrate side of the hard coat layer. The object of the present invention was also accomplished by a method for producing the optical sheet, comprising the steps of: forming a coating by applying a curable resin composition for a hard coat layer comprising reactive, irregularly shaped silica fine particles and a binder component onto one surface of a substrate, and forming a hard coat layer by curing the coating with or after preventing that the long axes of the reactive, irregularly shaped silica fine particles are each oriented in a direction planar to a virtual plane.

摘要： The main object of the present invention is to provide an optical sheet having excellent abrasion resistance and hardness, and a method for producing the same. The present invention provides an optical sheet in which a hard coat layer is provided on one surface of a substrate, wherein the hard coat layer comprises a cured product of a curable resin composition for a hard coat layer, which comprises reactive inorganic fine particles and a binder component, and wherein fine protrusions are provided on an interface on the side opposite to the substrate side of the hard coat layer, in which the minimum angle of each of the fine protrusions making angles with a virtual plane that is parallel to the hard coat layer is an acute angle. The present invention also provides a method for producing the optical sheet, comprising the steps of: forming a coating by applying a curable resin composition for a hard coat layer to one surface of a substrate, which composition comprising reactive, irregularly shaped silica fine particles and a binder component, and forming a hard coat layer and fine protrusions by curing the coating while or after preventing that the long axes of the reactive, irregularly shaped silica fine particles are each oriented in a direction planar to a virtual plane.
