Abstract
A number of alkyl cinnamates and related compounds have been synthesized. Upon irradiation in solution, some of the materials undergo cis-trans isomerization and a cycloaddition reaction. Application of these compounds to lignin-free paper does not suppress these reactions. The cinnamates were evaluated as UV screens for preventing the photo-yellowing of the lignin-rich paper. None of the compounds proved to be highly effective, and this result is important for a deeper understanding of the role of UV screens for preventing the light brightness reversion of high-yield pulps.
