A radiation curable composition for UV LED curing includes at least one co-initiator selected from the group consisting of an aliphatic tertiary amine and a dialkyl aniline derivative; and at least one specific carbazole photoinitiator. The radiation curable composition can be advantageously used to prevent unstable yellowing behaviour in an image upon storage.
