A coloring composition added to a solid such as a solid resin is disclosed. The composition includes (i) a soluble coloring agent precursor obtained by substituting a hydrogen atom of a NH group of a pigment molecule having at least one NH group with an alkoxycarbonyl group of the following general formula (1):
wherein R represents a tert-butyl group, a tert-amyl group, a 2-phenyl-2-propyl group or a diphenylmethyl group, (ii) an acid proliferation agent newly generating an acid by an action of an acid, and (iii) an acid former generating an acid by the action of activation energy rays or heat.
