Abstract
The ink receptor media of the invention comprise an ink receptor comprising surfactant templated mesoporous particles dispersed within an organic binder on the substrate. The ink receptor media may also have an ink fixing material within or on the ink receptor. The invention also describes surfactant templated silica particles having a narrow particle size distribution and having intraparticle pore sizes of about 1.5 to about 10 nm and methods of preparing said particles. The invention also describes a colloidal dispersion of STM particles methods of making said dispersions.
