Tannic acid-based monomer（TAM） and isosorbide-based reactive diluent（ISD）were successfully synthesized from tannic acid and isosorbide for UV-curable coatings.The monomer structure and coatings film properties were characterized by nuclear magneticresonace（1HNMR）， infrared（FT-IR）， thermogravimetric analyzer（TGA）， differential scanning calorimetry（DSC）and dynamic mechanical analyzer（DMA）.The effect of different levels of ISD on film properties was investigated.The results showed that the reactive diluentcould optimize the performance of the coatings in a certain degree.With the increase of ISDcontent，the hardness，storage modulus and glass transition temperature（Tg）of the coatingsfilm increased first and then decreased.The coated film ISD 50 showed the best performancewhen the ISD mass fraction was 50%.
