ABSTRACT:
The adsorption of anionic dyes on nanosize alumina modified silica particles to form colored pigments is disclosed. The dyes are chemisorbed and their uptake is controlled by the strong chemical reaction between positive surface of the absorbent and negative charge of the adsorbates. The prepared pigments are useful in the formation of color films and their optical properties are described. Photoresists using nanosized pigments are also disclosed herein which are useful in making color filters for liquid crystal displays.
