Curing with excellent balance between hydrophilicity and wear resistance, maintaining high hydrophilicity even after washing with water, and maintaining hydrophilicity with less contamination (or easy to desorb) even after long-term storage or heating An object (for example, a film made of the cured product) and a composition capable of obtaining the cured product are provided. A composition containing the copolymer (i) containing the structural unit represented by a specific chemical formula and the amino resin (ii) is cured to produce a cured product. |
