<P>PROBLEM TO BE SOLVED: To provide an optical article capable of suppressing interference fringe and having excellent impact resistance. <P>SOLUTION: The optical article 1 has a plastic substrate 10, a first layer 11 being the first layer 11 in contact with the plastic substrate 10 and having refractive index decreased toward a direction away from the plastic substrate 10, a second layer 12 being the second layer 12 in contact with the first layer 11 and having refractive index smaller than that of the surface layer 11b of the first layer 11 and a hard coat layer 13 being the hard coat layer 13 in contact with the second layer 12 and having refractive index smaller than that of the plastic substrate 10. <P>COPYRIGHT: (C)2010,JPO&INPIT |
