Curable compositions contain at least one polymerizable ionic species and, when cured (for example, by photocuring), provide cured compositions which are thermoplastic and yet fragmentable by a protic liquid medium such as water. The polymerizable ionic species corresponds to Formula (I) A+B− wherein A+ is a cationic species having a cationic functional group and a first polymerizable, ethylenically unsaturated functional group; and B″ is an anionic species having an anionic functional group and a second polymerizable, ethylenically unsaturated functional group which is the same as or different from the first polymerizable, ethylenically unsaturated functional group. The curable compositions are useful for forming sacrificial or temporary articles, for example by three-dimensional printing methods.
