Abstract:
In one aspect, water removable compositions are described herein, including for use in various printing applications. In some embodiments, a composition described herein comprises 50-95% by weight alcohol wax having the formula CH3(CH2)nOH, wherein n is an integer from 15 to 40; 5-50% by weight tackifier; and 0.5-5% by weight colorant. In other instances, a composition described herein comprises 50-95% by weight carboxylic acid wax having the formula CH3(CH2)mCOOH, wherein m is an integer from 14 to 40; 5-50% by weight tackifier; and 0.5-5% by weight colorant. Additionally, in some cases, the tackifier of a composition described herein comprises a rosin acid, a rosin ester, a rosin alcohol, or a mixture or combination thereof. Further, the solubility of a colorant in a composition described herein can be characterized by a spectral strength delta value of 5% or less or 3% or less.
