Abstract
A curable solid ink composition including a curable component, a non-curable component including an ethoxylated octylphenol derivative, a photoinitiator, and a colorant. The curable solid ink composition has a viscosity in the range of less than 10 cPs at 90° C., a shrinkage value of less than 3%, and a superior curing rate compared to existing curable solid ink compositions. The ethoxylated octylphenol derivatives may be prepared by reacting an ethoxylated octylphenol, a linear alcohol, and diisocyanates or polyisocyanates.
