<p><P>PROBLEM TO BE SOLVED: To provide a hard coat film for injection molding capable of imparting sufficient scratch resistance to the surface of an injection-molded object, enabling the integration of a resin simultaneously with molding at the time of the injection molding of the resin, excellent in productivity, enhanced in stretchability at the time of injection molding and capable of sufficiently corresponding, for example, even to an angular shape. <P>SOLUTION: The hard coat film 1 is constituted by making a hard coat layer 3 overlie one side or both sides of a base material layer 2 containing polycarbonate and polyester. The hard coat layer comprises a cured material of an ultraviolet curable resin composition containing an acrylic polymer, a polyfunctional oligomer, a monomer component and a photopolymerization initiator and is characterized in that the average number of functional groups in a compound group composed of the polyfunctional oligomer and the monomer component is 2.4-4.9 and the mass ratio of the acrylic polymer/(polyfunctional oligomer+monomer component) is within a range of 2/98-42/58. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
