An aqueous curable composition includes a water-soluble photopolymerization initiator having a structure in which one or more carbonyl groups further directly bond to an aromatic ring of an aromatic acyl group that bonds to a phosphorus atom in an acylphosphine oxide structure, water, and a polymerizable compound. A novel water-soluble photopolymerization initiator is a compound represented by formula 1-1 or formula 2-1.

The present invention describes water-soluble homopolymers obtained by polymerization of monomers containing multiple unsaturations. These monomers form inclusion complexes with cyclodextrins and methylated cyclodextrins. The unsaturated site involved in the formation of the inclusion complex does not take part in the polymeization reaction. After cyclodextrin is recovered, the polymer containing multiple unsaturations can be further polymerized either by thermal and/or photochemical initiators to yield crosslinked polymers.
