Title: THREE-DIMENSIONAL OBJECT PRECURSOR TREATMENT COMPOSITION
Abstract:
A three-dimensional object precursor treatment composition for removing a support material from a three-dimensional object precursor including a three-dimensional object and the support material including a (meth) acrylate copolymer having a hydrophylic monomer and a hydrophobic monomer as monomer units therefor. The three-dimensional object precursor treatment composition includes at least one type of organic amine compound selected from the group consisting of a secondary monoamine compound, a tertiary monoamine compound, a secondary diamine compound, and a tertiary diamine compound. The total alkali metal hydroxide and alkali metal carbonate content is less than the organic amine compound content and is less than 2.5 mass%. As a result, a three-dimensional object precursor treatment composition can be provided that is capable of removing a support material containing a (meth) acrylate copolymer more rapidly than conventional compositions.
