COLORING COMPOSITION

摘要

A coloring composition which is added to solids such as solid resins. The composition comprises: (i) a soluble colorant precursor formed from a colorant having at least one NH group in the molecule by replacing the hydrogen atom of the NH group with an alkoxycarbonyl group represented by the general formula (1) (wherein R represents tert-butyl, tert-amyl, 2-phenyl-2-propyl, or diphenylmethyl); (ii) an acid multiplier which newly generates an acid by the action of an acid; and (iii) an acid generator which generates an acid by the action of actinic energy rays or heat.
