A radiation curable coating composition based on thiol-ene chemistry is disclosed. The coating composition comprises at least one novel thiol having a mercapto functionality of at least two and at least one compound having an alkenyl functionality of at least two. Said novel thiol is a reaction product between at least one alkoxylated di, tri or polyhydric alcohol and at least one mercapto carboxylic acid and said alkenyl functional compound is preferably an allyl or methallyl ether of a di, tri or polyhydric alcohol and/or an ester of an unsaturated carboxylic acid, such as a cycloalkene or a bicycloalkene carboxylic acid, and a di, tri or polyhydric alcohol. In a further aspect the present invention refers to the novel thiol included in said coating composition. |
