摘要:
A stabilized color pigment dispersion includes a phosphated polymer, a color pigment stabilized in the phosphated polymer, and an aqueous carrier. The color pigment comprises one or more oxide color pigments and is essentially free from metallic pigments. The stabilized color pigment dispersion comprises in a range of from about 20% to about 80% of water, percentage based on the total weight of the stabilized color pigment dispersion.

摘要:
A nanoscale pigment particle composition includes a fluorescent compound, such as a benzothioxanthene pigment, including at least one functional moiety, and a 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 particles.
摘要:
The invention concerns a pigment preparation based on C.I. Pigment Yellow 155, containing 0.1% to 50% by weight, based on the weight of C.I. Pigment Yellow 155, of at least one pigment dispersant from the group of monoazo or disazo pigments substituted with at least one sulfonic acid group, characterized in that it has a chroma C greater than 53 in the CIELAB system in a solventborne alkyd melamine varnish comprising a 6.7% by weight concentration of the pigment preparation, and/or in that it has a chroma C greater than 35 in the CIELAB system in an aqueous base varnish system in a white reduction comprising a 0.2% by weight concentration of the pigment preparation in white reduction.
摘要:
