Pigments mixing

An accurate observation of the first crater produced during the LIBS measurement with a camera revealed the presence of a blue substrate under the upper red layer of painting. The LIBS analysis demonstrated that the underlying blue substrate is composed by azurite (a copper based pigment) mixed with white lead (Figure 7). 

Depending on the substituent R1 (CH3, CF3, Cl, Br, N(CH3)2), the resulting reddish yellow to bluish violet pigments show excellent lightfastness and weatherfastness and very good migration fastness. If two differently substituted benzoni-triles are used, the product is a mixture of the symmetrically substituted and the two unsymmetrically substituted diphenyl-DDP pigments (mixed synthesis).

Mixed-Metal Oxide Pigments. Mixed-metal oxide pigments can be considered a subcategory of complex inorganic color pigments. The name, mixed-metal oxides, does not, however, represent the reality as these pigments are not mixtures but rather solid solutions or compounds consisting... 

Use an eye dropper to add, drop by drop, enough of each of the four binders prepared in Activity 2.4 to each pigment, mixing thoroughly, to make a colloidal suspension. 

Intestines were often used as casings for sausage and other foods. They were also used as condoms and to hold and carry water or other substances. Intestines were sometime slit lengthwise and dried like leather. The stomachs of larger animals were sometimes used as containers for water and other liquids. The stomachs and bladders of animals were used as pouches or bags to store pigments, mixed paints, herbs, medicines, and other powdered materials. 

Development. This is obtained through the electrical attraction of a toner (thermoplastic pigment mixed with carbon black), whose fine particles carry electrical charges that are opposite in polarity to the latent electrostatic image charges. 

A sol is a fluid colloidal system in which fine solid particles are dispersed in a liquid medium. Most household paints are sols with finely ground pigments mixed with acrylic resins dissolved in water. Paint is applied to a surface as a liquid.

The Concentrate is a high level of pigment mixed with pulverized polyethylene. This preblend is then extruded on a twin-screw. The concentrate is letdown at end use levels and compounded on a single screw extruder. The compound is then injection molded to make displays. 

Methods are available for fine-tuning dye and pigment mixes by, for example, optimizing tristimulus values or using simplex methods. Such methods can be used to minimize metamerism and pigment costs. The many problems of dye and pigment formulation can be surmounted using specific equations for specific applications. 

Method of painting in which pigments mixed only with water are applied to a freshly laid surface of lime plaster. The painted surface is rendered durable by the pigment absorbing calcium hydroxide from the wet plaster, which is converted into insoluble calcium carbonate as the surface dries. The term is sometimes used incorrectly to denote any form of mural painting.

This paper is the seventh in a series discussing colloid chemistry, and focuses on latex paints. These are defined, and then discussed under the following headings terminology, general features, inherent contradictions, emulsion paints as latex-based compositions, latex characterisation, colloid characteristics, latex modification, latex stability, latex paints as polymers and pigment mixed dispersions, functional additives, and paint stability. 5 refs. 

There are two types of photosystems with different colors, one the purple-pink of rhodopsin and the other the green of spring leaves (with some orange carhon-chain pigments mixed in). Most familiar plants have both photosystems, connected with a flow of electrons. Each system is built around chlorophyll, but it uses that chlorophyll for a different purpose. On the other hand, many photosynthetic microbes have only one photosystem.
