Artificial Urushi: Design, Synthesis, and Enzymatic Curing of New Urushiol Analogues

Abstract

Abstract “Artificial urushi” was prepared by laccase-catalyzed curing of new urushiol analogues. The curing of the catechol derivative having a linolenoyl group proceeded in the presence of acetone powder, yielding the crosslinked film (artificial urushi) with high hardness and gloss surface, which are comparable with those of natural urushi coating.
