Abstract
(EN)
One embodiment of the present invention is a molded body that comprises a resin substrate and in which: a part or all of the surface of the substrate is coated with a hard coat; a first hard coat is formed from a coating material that does not contain inorganic particles and that contains (A) 100 parts by mass of a polyfunctional (meth)acrylate, (B) 0.01-7 parts by mass of a water-repelling agent, and (C) 0.01-10 parts by mass of a silane coupling agent; and a second hard coat is formed from a coating material containing (A) 100 parts by mass of the polyfunctional (meth)acrylate and (D) 50-300 parts by mass of fine inorganic particles having an average particle size of 1-300 nm. Another embodiment of the present invention is a molded body that comprises a resin substrate and in which a part or all of the surface of the substrate is coated with a hard coat, a first hard coat is formed from a coating material that does not contain inorganic particles, a second hard coat is formed from a coating material containing inorganic particles, (i) the total light transmittance is 85% or more, and (ii) the pencil hardness of the surface of the first hard coat is 5H or more.
