A potentially hydrophilic resin comprises at least monomer units readily saponifiable under alkaline conditions to form carboxyl groups, carboxyl-containing monomer units, and hydroxyl-containing monomer units. A potentially hydrophilic resin composition comprises, in a liquid medium, the potentially hydrophilic and an adhesive component or film-forming component. A recycling method is provided for an article with a coating applied on a surface thereof. According to the recycling method, the coating on the surface of the article is formed with the potentially hydrophilic resin composition, and subsequent to use of the article, the article is treated with alkaline water to saponify methyl acrylate in the coating such that the coating is caused to swell, and the coating so swollen is removed from the article. |
