Color density

The dyes used in the ink sheet must satisfy various requirements (/) optimum color characteristics of the three primary colors (hue, color density, shape of absorption spectmm) (2) sensitivity, ie, sublimabiHty from ink sheet to acceptor sheet (3) fastness for light and migration and (4) compatibiHty with the resin in the ink sheet. With respect to these characteristics, a large number of anthraquinone dyes have been proposed particularly for magenta and cyan colors. Typical examples are given in Table 8 and Table 9. 

The density of a substance is independent of the size of the sample because doubling the volume also doubles the mass so the ratio of mass to volume remains the same. Density is therefore an intensive property. We distinguish different substances by their intensive properties. Thus, we might recognize a sample as water by noting its color, density (1.00 g-cm-3), melting point (0°C), boiling point (100°C), and the fact that it is a liquid. 

Orbital pictures have an advantage over electron density plots in that they can indicate the three-dimensional nature of orbitals. One type of orbital picture is a two-dimensional color pattern in which the density of color represents electron density. Figure 7-19Z> shows such an orbital density picture of the 2s orbital. This two-dimensional pattern of color density shows a cross-sectional slice through the middle of the orbital.

The value of an intensive response is not a function of the size or throughput of the system. Product purity is an example of an intensive response. If a manufacturing facility can consistently produce 95% pure material, then it will be 95% pure, whether we look at a pound or a ton of the material. Other examples of intensive responses might be color, density, percent yield, alcohol content, and flavor.

Elemental composition Os 74.82%, 0 25.18%. The compound can be identified by its physical properties, such as, odor, color, density, melting-, and boiling points. Its acrid odor is perceptible at concentrations of 0.02 mg/hter in air. The oxide also produces an orange color when a small amount of the compound or its aqueous solution is mixed with an aqueous solution of ammonia in KOH (see Reactions). Aqueous solution of the tetroxide may be analyzed for osmium by AA or ICP spectrometry (see Osmium). Vapors of the tetroxide may be purged from an aqueous solution by helium, adsorbed over a trap, and desorbed thermally by helium onto a GC. Alternatively, a benzene or carbon tetrachloride solution may be injected onto the GC and the compound peak identified by mass spectrometry. The characteristic mass ions for its identification should be 190 and 254.

The methodologies used to measure color density and polymeric color were developed for fruit juices, which naturally have an acidic pH. If the material to be measured has a pH in the neutral or alkaline range, the pH of the solution should be lowered with a weak acid. In these cases, the authors recommend the use of a 0.1 M citric acid buffer, pH 3.5, instead of distilled water to prepare the different dilutions.

A physical property is one that identifies an object. In addition to color, density, mass, and shape are physical properties. Carbon and chlorine are represented by their color. 

PCB formulations are mixtures designed to fulfill unique specifications (color, density, dielectric constant, fire and flash point, percent chlorine, etc.) Such mixtures may vary from batch to batch. There is some evidence that the presence of trace quantities of chlorinated napthalenes and dibenzofurans in commercial PCBs may be of toxicologic significance (ref. 134, p. 52).
