Abstract
[Problem to be Solved]To provide: an antifog optical article wherein a suitable water-repellent layer is formed in the process of application of antifog coating having a water-absorbing layer consisting primarily of urethane or acrylic resin having a polyoxyethylene chain on a base material; and a manufacturing method of the antifog optical article.[Solution] A water-absorbing layer consisting primarily of urethane or acrylic resin having a polyoxyethylene chain represented as —(CH2CH2O)n- is formed on a surface of a glass or plastic base material, a water-repellent layer consisting primarily of at least one of amino-modified silicone and mercapto-modified silicone is formed on a surface of the water-absorbing layer, and a contact angle with respect to water on a surface of the water-repellent layer is set equal to or larger than 100 degrees.
