The curable composition comprises at least one polymerizable ionic substance and, when cured (eg, by photocuring), provides a cured composition that is thermoplastic and also capable of being cured by Fragmentation occurs in protic liquid media such as water. The polymerizable ionic substance corresponds to formula (I): A + B- (I), wherein A + is a cationic substance having a cationic functional group and a first ethylenically unsaturated functional group capable of polymerizing; and B- It is an anionic substance having an anionic functional group and a polymerizable second ethylenically unsaturated functional group which is the same as or different from the first polymerizable ethylenically unsaturated functional group. The curable composition is used to form sacrificial or temporary articles, such as by three-dimensional printing methods. |
