Presented here are INK JET INK Colors By Belleville Coders

They are pigment based inks dispersed in a fluid media such as acetone or alcohol as solvent for a polymer binder with a dispersed color pigment.

COLORANT CHEMICAL ANALYSIS

While the binder, solvent compositions, and additives are unknown, color pigments can indicate pigment chemical composition and be identified simply from there color and physical property requirements. For example, the color blue is phthalocyanine (PCN) blue. It is one of the most stable and light fast pigments available. The PCN blue is available in red and green shades also. Further, it has been used for many years in paints, inks, and plastics as the blue color component and has proven superior to other possible blue pigments that do not have it’s properties. The PCN molecule is a chelate structure with copper atom at the center of the molecule and the surrounding structure of cyclic hydrocarbon atoms. It should also be noted that copper is sometimes considered a toxic heavy metal however, in this case the copper atom is bound tightly in the inter structure of the molecule and considered nontoxic by most.

The green color is again most likely a PCN since it is easy to replace some of the hydrogen atoms in the outer molecule structure with chlorine atoms in the pigment manufacturing process thus changing the color to green or PCN green and again the same excellent physical properties.

The yellow color is not as distinctive since there are two possible pigments Hansa yellow and Diarylide yellow having excellent physical properties. These are azo coupling structures.

The orange and red colors are possible the least distinctive colors in terms of chemical compositions since there are many possible pigments with good light fast properties, however, these

Pigments are not bright in color. Example pigments are Pyrazolone red Quinacridone red (polycyclic dyes made insoluble)and BON red (beta oxyie napthlic acid), however, some printers have chosen less lightfast pigments that are brighter and cleaner in color for there magenta color, (usually a rhodamine pigment). Further, this is easily seen in old color posters that have CMYK registered printing in which the color after fading is mostly blue (the most light fast pigment remaining). It should be noted that CMYK stands for Cyan (the blue component), Magenta(the red component),Y (the yellow component), and lastly the K as the black component .

The White and Black pigments are again very distinctive since the white pigment is Titanium dioxide (TiO2) and the black is carbon black. The TiO2 has the property of the highest refractive index of any white pigment, further, it is easy to disperse into sub micron particles. The Black is Carbon Black and again is sub micron in particle size depending on structure. This structure depends on the manufacturing process.
