Delivery systems for various functional compounds are disclosed. This delivery system uses a composition containing silica and / or alumina. Various functional materials containing specific residues can be adsorbed onto silica and / or alumina and used as desired. The functional compound may be, for example, a drug, a foreign substance, an antibacterial agent, an antiviral agent, an ultraviolet absorbent, a deodorant, a fragrance or the like. For example, in one particular embodiment, certain dyes may be adsorbed onto the alumina surface. Once the dye is adsorbed onto the alumina surface, the resulting particles are combined with the liquid vehicle and used for any suitable printing process.n n n Functional Compounds, Delivery Systems, Trigger Release, Alumina, Silica |
