This paper is the second part of a two-part contribution. The first part appeared in the November 2022 edition of the European Coatings Journal (page 34). In UV-curable coatings, reactive diluents not only can reduce the viscosity of the resin, but also can participate in film formation and thus be used to adjust the coating properties [1-5]. Many bio-based raw materials have therefore been developed and utilised in the preparation of reactive diluents in the past decades; they include itaconic acid [6] and isosorbide [7]. Wei et al. used bio-sourced isosorbide as a starting material ...
