Abstract
Provided is a curable composition including a urethanization reaction product of: a branched polyolefin diol having a carbon-carbon double bond in a side chain; at least one selected from an isocyanurate product, an adduct product, and a biuret product, of an aliphatic diisocyanate having 6 or more and 10 or less total carbon atoms; and a hydroxy saturated C1 to C4 alkyl (meth) acrylate. Also provided are a method for producing the curable composition, and a specific curable compound included in the curable composition.
