Photocrosslinkable products derived from hemp oil, their preparation and their use for photosensitive inks and coatings

摘要

Hemp oil is epoxidised by reaction with a peracid and the product obtained is then treated with an alpha , beta -ethylenic acid to give polymers carrying unsaturated groups. These polymers are copolymerised with ethylenic monomers under the action of luminous radiation or thermally. Application to the preparation of photocrosslinkable inks and surface coatings.
