Abstract
The present invention is a composition of an agent for treating a precursor of a three-dimensional object for removing a support material from the precursor of the three-dimensional object containing a three-dimensional object and the support material containing a (meth)acrylic acid-based copolymer having a hydrophilic monomer and a hydrophobic monomer as a monomer unit; the composition of the agent for treating the precursor of the three-dimensional object having at least one or more type of organic amine compounds selected from the group consisting of a secondary monoamine compound, a tertiary monoamine compound, a secondary diamine compound, and a tertiary diamine compound; in which a total content of alkali metal hydroxide and alkali metal carbonate is less than a content of the organic amine compound and less than 2.5% by mass. The present invention can provide a composition of an agent for treating a precursor of a three-dimensional object that is capable of removing the support material containing a (meth)acrylic acid-based copolymer more quickly than before.
