Title
(EN) MOLDED BODY
(JA) 成形体
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a molded body having a three-dimensional shape excellent in surface hardness and scratch resistance.

SOLUTION: There is provided a molded body having a resin base, where the base has a part or all of a surface coated with a hard coat, the hard coat has a layer of a first hard coat and a layer of a second hard coat in order from the surface side, the first hard coat contains (A) polyfunctional (meth)acrylate of 100 pts.mass; (B) a water-repellent agent of 0.01-7 pts.mass; and (C) a silane coupling agent of 0.01-10 pts.mass, and is formed from a coating material containing no inorganic particle, and the second hard coat is formed from a coating material that contains (A) polyfunctional (meth)acrylate of 100 pts.mass; and (D) inorganic fine particles having an average particle size of 1-300 nm of 50-300 pts.mass.
