Abstract: Embodiments relate to a hard coat-laminated film for a touch panel display face plate, the hard coat-laminated film including: a transparent resin film, and a hard coat formed on at least one surface of the transparent resin film from a coating material including an active energy ray-curable resin composition. The hard coat-laminated film meets the following requirements (1-i) to (1-v): (1-i) a total light transmittance of 80% or higher, (1-ii) a haze of 3.0% or lower, (1-iii) a yellowness index of 3 or lower, (1-iv) a water contact angle of a touch surface of 100° or larger; and (1-v) a water contact angle of the touch surface of 100° or larger after 20,000-times reciprocal cotton wiping of the touch panel.

Abstract: Embodiments of the invention relate to an actinic-ray-curable resin composition which includes 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. Embodiments of the invention also relate to a layered transparent resin product which includes a hardcoat layer and a layer of a transparent resin sheet in this order from the outermost layer side, wherein the hardcoat has been formed from a coating material including 100 parts by mass of a polyfunctional (meth)acrylate; 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; 0.05-3 parts by mass of an organic titanium; and 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm.

Abstract: Embodiments relate to a hard coat laminated film having a first hard coat, a second hard coat, and a transparent resin film layer, where: the first hard coat is formed from paint which contains predetermined amounts of (A) a multifunctional (meth)acrylate, (B) a water repellent, and (C) a silane coupling agent, and which does not contain inorganic particles; and the second hard coat is formed from paint containing predetermined amounts of (D) a polymerizable compound and (E) inorganic fine particles having an average particle size of 1-300 nm. The (D) polymerizable compound contains: (d1) a multifunctional (meth)acrylate having three or more (meth)acryloyl groups in one molecule; (d2) a compound having two or more secondary thiol groups in one molecule; and optionally, (d3) at least one (meth)acrylate selected from the group consisting of a (meth)acrylate having two (meth)acryloyl groups in one molecule, a (meth)acrylate having one (meth)acryloyl group in one molecule, and a urethane(meth)acrylate.
