摘要
A mixture of a benzophenone derivative having hydroxyl and alkoxysilyl groups and a benzophenone derivative having silyloxy and alkoxysilyl groups provides a reactive UV absorber which is unlikely to gel, stable during shelf storage, and curable. A coating solution comprising the UV absorber cures at room temperature to form a UV-screening film which has adhesion to glass and plastic substrates, scratch resistance, and bleed resistance, and maintains a UV-screening function over time.
