SILICA ENCAPSULATED ORGANIC NANOPIGMENTS AND METHOD OF MAKING SAME |
摘要 |
<p>Core-shell nanoscale pigment particles include a core organic pigment composition including nanoscale particles of organic pigments, and a shell layer of surface-deposited silica, where the organic pigment particles are selected from azo-type pigment particles, azo laked pigment particles, quinacridone pigment particles, phthalocyanine pigment particles, and mixtures thereof. The core-shell nanoscale pigment particles can also include an organic primer layer covering the core and located between the core and the shell layer. The core-shell nanoscale pigment particles can be made by preparing a core composition including nanoparticles of organic pigments, and encapsulating the core with shell layer of surface-deposited silica and an optional organic primer layer located between the core and the shell layer.</p> |
