摘要:
A light-cyan solid ink including an ink vehicle and a colorant. The colorant includes a cyan colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 500 to about 600 run, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm.
摘要:
A nanoscale pigment particle composition includes an organic monoazo laked pigment including at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, wherein the functional moiety associates non-covalently with the functional group; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.
摘要:
Radiation curable compositions, such as UV curable ink compositions, contain a polymeric dispersant, a curable material, and a nanoscale pigment particle composition including an organic monoazo laked pigment including at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, wherein the functional moiety of the pigment associates non-covalently with the functional group of the stabilizer; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.
摘要:
A nanoscale pigment particle composition includes an organic monoazo laked pigment including at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, wherein the functional moiety on the pigment associates non-covalently with the functional group of the stabilizer; and the nanoscale pigment particles have an average particle size of from about 10 nm to about 500 nm and have tunable coloristic properties that depend on both particle composition and average particle size.
