摘要:
The disclosure provides transitorially erasable ink compositions, including an aliphatic hydrocarbon solvent, a rubber dissolved in the aliphatic hydrocarbon solvent, a hydrophilic pigment, and a surfactant. The disclosure further provides methods of preparing transitorially erasable ink compositions and writing instruments comprising transitorially erasable ink compositions. The disclosed erasable ink compositions write well, have strong color and erase easily transitorially, and demonstrate color stability.
