An Siliziumoxyd gebundenes Ozon-Schutzmittel zur Verwendung in Druckmaterialien |
摘要 |
A method of protecting dyes printed on print media against ozonolysis is provided. The method comprises: (a) providing a first reaction product comprising the reaction of a phenylenediamine or derivative thereof (an anti-ozonant) with a silica or silicate; and (b) reacting the first reaction product in the presence of a water-free solvent with silica groups to form a second reaction product. Also provided is the reaction product resulting from the reaction of (1) the anti-ozonant-silica (or silicate) and (2) silica groups on a substrate. The anti-ozonant-silica (or silicate) is covalently attached to the particles of silica in the media and cannot escape or evaporate away. The use of phenylenediamines as anti-ozonants solves the problem of the fading of dyes on porous media by ozone pollution. |
