PURPOSE:To improve shock resistance, abrasion resistance, durability, and heat resistance by improving adhesion of a hard coat film, by a method wherein a hard coat layer is formed on a transparent substrate wherein at least a part of the surface is comprised by being alkaline-solution-treated and it consists mainly of resin containing sulphur. CONSTITUTION:A hard coat layer is formed on a transparent substrate wherein a part of the surface is comprised by being alkaline-solution-treated and it consists mainly of resin containing sulphur. Hereupon, the resin containing the sulphur is the resin to be obtained by polymerizing a monomer composition containing at least 10wt.% monomer possessing at least 1 thiol(meta)acrylate group. Then it is preferable that the resin have a refractive index of 1.54-1.70. Then the hard coat layer consists mainly of organosiloxane and a particulate inorganic oxide. Then it is preferable that the inorganic oxide is contained within a range of 5-80wt.%. |
