OPTICAL ARTICLE PROVIDED WITH HIGH-STRENGTH HARD COAT LAYER |
| 摘要 |
One aspect of the present invention relates to an optical article comprising:
an optical substrate;a hard coat layer provided directly, or over another layer(s), on the optical substrate;an antireflective layer provided on the hard coat layer; andan antifouling layer provided on the antireflective layer;such that when a friction and wear test is conducted on the surface of the antifouling layer under conditions of a scratching rate of 0.1 mm/s and a load increase rate of 0.15 gf/s with a diamond stylus having a tip diameter of 0.03 mm, the load at which the antireflective layer begins to peel off is greater than 50 gf. |

1. An optical article comprising:
an optical substrate; a hard coat layer provided directly, or over another layer(s), on the optical substrate; an antireflective layer provided on the hard coat layer; and an antifouling layer provided on the antireflective layer; such that when a friction and wear test is conducted on the surface of the antifouling layer under conditions of a scratching rate of 0.1 mm/s and a load increase rate of 0.15 gf/s with a diamond stylus having a tip diameter of 0.03 mm, the load at which the antireflective layer begins to peel off is greater than 50 gf. |
