Characterization by Tga and Uv-visible of new pigment materials containing mica, P4VP and D&C red 6 dye
Résumé
The pigments and dyes industry must constantly develop new products with more innovative visual effects. Various industrial sectors such as cosmetics, textile fibers, painted paper and ceramics...etc, need new optical effects for their commercial products. The field of study of these pigments is vast and the market is in full expansion. Among the desired optical effects, manufacturers try to imitate nature by creating the appearance of increasingly sophisticated products: for example interferential compounds changing color and aspect under the effect of the light and according to angle. These effects can be achieved through the existence of highly ordered structures defined and organized within compounds to be developed. In our work, we succeeded in formulating new pigmentary materials by adsorption of polymer on mica particles and fixation of D&C Red 6 dyes on polymer. These new pigmentary materials can either differ by their colors, or to present interferential effects. Copyright © 2013, AIDIC Servizi S.r.l.
