Title: Coating composition comprising hydroxylamine esters

Abstract: The invention relates to a dual thermal and ultraviolet radiation curable coating composition, comprising a) at least an ethylenically unsaturated compound; b) a hydroxylamine ester effective to enable IR-curing or NIR-curing of the ethylenically unsaturated compound; c) a photoinitiator effective to enable UV-curing of the ethylenically unsaturated compound; wherein the thermal initiator is a hydroxylamine ester which has a structural element of formula (1) or formula (1) or a polymeric hydroxylamine ester which has a repetitive structural unit of formula (11) or (I[') of formula (11) Furthermore, the invention relates to a process for curing a thermal curable coating composition composing hydroxylamine esters as thermal initiators using NIR-curing. ##STR00001##
