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.

Uma resina potencial hydrophilic compreende ao menos condições alcalinas inferiores prontamente saponifiable das unidades do monomer para dar forma aos grupos carboxyl, carboxyl-contendo unidades do monomer, e hydroxyl-contendo unidades do monomer. Uma composição potencial hydrophilic da resina compreende, em um meio líquido, o componente potencial hydrophilic e adesivo ou componente film-forming. Um método recycling é fornecido para um artigo com um revestimento aplicado em uma superfície disso. De acordo com o método recycling, o revestimento na superfície do artigo é dado forma com a composição potencial hydrophilic da resina, e subseqüente ao uso do artigo, o artigo é tratado com água alcalina para saponify o acrylate methyl no revestimento tais que o revestimento está causado ao inchamento, e no revestimento assim que inchado é removido do artigo.
