Abstract:
1. An optical layered body comprising a light-transmitting substrate and a hard coat layer on at least one surface of the light-transmitting substrate, wherein the hard coat layer contains antimony pentoxide and a hexa- or higher functional urethane (meth)acrylate oligomer with a weight average molecular weight of not lower than 1000 and lower than 10000; a content of the antimony pentoxide is 7 to 35% by mass in the hard coat layer; a content of the urethane (meth)acrylate oligomer is 30 to 70% by mass in the hard coat layer; the antimony pentoxide is dispersed in the hard coat layer while forming a three-dimensional net structure; and the optical layered body has a haze of not higher than 0.7%.
