METHOD FOR PREPARING A PHOTOCURABLE OLIGOMER USING VEGETABLE OIL AS A CURABLE MATERIAL FOR PRINTING, AND AN ENVIRONMENT-FRIENDLY PHOTOCURABLE INK USING THE SAME

摘要

PURPOSE: A method for preparing a photocurable oligomer is provided to be useful as an environment-friendly printing material using a resin obtained from unsaturated fatty acid that is vegetable oil as a photocurable ink material.;CONSTITUTION: A method for preparing a photocurable oligomer comprises the steps of: reacting unsaturated fatty acid represented by chemical formula 1 with ethylene; reacting the compound obtained from the first step with meta-chlorobenzoic acids; and reacting the compound obtained from the second step with acrylic acids. In chemical formula 1, m and n are an integer of 1-5. The unsaturated fatty acid is any one selected from oleic acid or linoleic acid.;COPYRIGHT KIPO 2010
