Patent ID: 8840992

Claim:
A hard coat layer, formed by curing a curable resin composition, wherein the curable resin composition comprising inorganic particles, a curable resin and a curing agent wherein the curable resin is an active energy ray-curable resin, the inorganic particles comprise an inorganic particle (a-1) having a Mohs hardness of 7 or more and an average particle diameter of 10 to 50 nm, an inorganic particle (a-2) having a Mohs hardness of 4 or more to less than 7 and an average particle diameter of 10 to 50 nm, and an inorganic particle (a-3) having a Mohs hardness of less than 4 and an average particle diameter of 10 to 50 nm; the curable resin is at least one selected from the group consisting of a thermosetting resin and an active energy ray-curable resin; and based on a total weight of the curable resin composition, a content of the inorganic particle (a-1) is from 20 wt % to 60 wt %, a content of the inorganic particle (a-2) is from 5 wt % to 20 wt %, a content of the inorganic particle (a-3) is from 0.1 wt % to 5 wt %, a content of the curable resin is from 15 wt % to 74 wt % and a content of the curing agent is from 0.1 wt % to 10 wt %, wherein the inorganic particle (a-1) is at least one selected from alumina and silica, the inorganic particle (a-2) is at least one selected from tin oxide, zirconia, cerium oxide, magnesium fluoride, copper oxide, apatite, fluorite, and ferric oxide, and the inorganic particle (a-3) is at least one selected from cryolite, calcite, gypsum, and talc, and the hard coat layer has a thickness of 10 μm or less.
