Anti-fog plates used in anti-fog sunglasses, ski goggles and the like are generally made of cellulose plastics subjected to saponification treatment to produce an anti-fog effect. However, they are unsuitable for industrial safety glasses, motorcycle windshield glasses, and other applications that require impact resistance.

が次第に低減し、消失するという欠点があつた。 Therefore, polycarbonate plates coated with a hydrophilic acrylic resin or coated with a mixture of polyvinyl alcohol, a surfactant, and other resins to form an antifogging film are also commercially available. However, these also have the disadvantage that the anti-fog coating surface is soft and water-absorbing, so the anti-fogging coating swells and peels off or dissolves, and the anti-fogging effect gradually decreases and disappears.
本考案の課題は、上記の欠点を解消し、耐久性
および耐衝撃性にすぐれた防曇板を提供すること
にある。 An object of the present invention is to eliminate the above-mentioned drawbacks and provide an anti-fog plate with excellent durability and impact resistance.
