Abstract

Provided is a method for making a curable composition that has low viscosity and rapid curing ability in the form of thin film, further has excellent resistance to emulsification and preservation stability, and has high hardness in the form of cured film, thereby achieving excellent alkali developability, which is preferably an active energy beam-curable composition, is provided. The made curable composition includes a mixture (A) of a compound having two or more (meth)acryloyl groups, and is obtained by conducting a transesterification reaction of diglycerin and/or glycerin and a compound having one (meth)acryloyl group under the presence of the following catalysts X and Y: catalyst X: a compound that is at least one member selected from the group consisting of cyclic tertiary amine having an azabicyclo structure or a salt or complex thereof, amidine or a salt or complex thereof, and a compound having a pyridine ring or a salt or complex thereof; and catalyst Y: a compound including zinc.
