Abstract
A liquid composition that is an aqueous liquid composition that emits light when irradiated with ultraviolet light contains a resin particle, the resin particle containing a unit that has a polar group and containing a complex composed of a sulfur-bridged calixarene and a lanthanoid ion, the polar group being at least one selected from the group consisting of an ester group, a carboxy group, a hydroxy group, an ether group, an amino group, an amide group and a cyano group.
