Abstract
A curable resin composition comprises a compound containing a primary hydroxyl group and a compound containing a ketone group, in which the compound containing the ketone group is a compound in which at least one of the carbon atoms adjacent to the carbonyl carbon bonds to a hydrogen atom, and the curable resin composition can give a cured product having a high crosslink density by means of a dehydrating reaction between the primary hydroxyl group and the ketone group and the subsequent crosslinking of a vinyl bond formed by the dehydrating reaction.
