An active-energy-ray-curable aqueous composition is provided that contains water, a polymerizable compound that undergoes radical polymerization in response to active energy rays, and a polymerization initiator (C1) that produces radicals in response to active energy rays. The polymerizable compound contains an acrylamide compound (A1) represented by General formula (1) or (4), and a bifunctional or higher polymerizable compound (B1):
where R
1
represents a C1-C6 alkyl group, X represents a C1-C6 alkylene, and Y represents a group represented by General formula (2) or (3):
where R
2
represents a C1-C10 alkyl group, and * represents a binding site with the X:
whererR
2
represents a C1-C10 alkyl group, and * represents a binding site with the X:
where the ring X
1
represents a ring structure containing a nitrogen atom and from two through five carbon atoms, R
4
represents a single bond, or a straight-chained or branched C1-C3 alkylene group, and R
5
represents a straight-chained or branched C1-C10 alkyl group.
