摘要 |
<p>Thermoplastic substrates subject to color instability and loss of physical properties resulting from exposure to ultraviolet radiation, such as polycarbonate, are coated with a protective coating comprising at least one thermoplastic acrylic polymer such as poly(methyl methacrylate) in combination with two ultraviolet absorbing compounds: a substituted resorcinol such as 4,6-dibenzoylresorcinol and a silylated substituted resorcinol such as 2-(3-triethoxysilylpropyl)-4,6-dibenzoylresorcinol. The silylated substituted resorcinol is used in a minor proportion effective to improve solubility and compatibility of the substituted resorcinol.</p> |
