The invention provides a method of forming a cured coating film which comprises exposing a coating composi- tion consisting of, or containing as a main component, a resin containing polymerizable unsaturated group and aprotic onium-containing group of the formula Image (I) wherein R1 means a hydrogen atom or a hydrocarbon group of 1 to 8 carbon atoms which may optionally be substituted by a hydroxyl, alkoxy or ester group or a halogen atom; Image means Image or Image where Z means a nitrogen atom or phosphorus atom and Y means a sulfur atom; R2, R3 and R4 are the same or different and respectively mean an organic group of 1 to 14 carbon atoms, provided that R2 and R3, or R2, R3 and R4 may jointly form a heterocyclic group taken together with the adjacent nitrogen, phosphorus or sulfur atom, to actinic radiation or electron beams to thereby induce a crosslinking reaction and, then, subjecting the composition to heat treatment at a temperature not less than 80°C.
