DPP Pigments were invented in the early 1980's.
Although, these pigments are small, but these pigments are considered as
very important group of synthetic pigments. The intense Light fastness
property was gradually developed in these pigments synthetically. The
types of currently present DPP Pigments are:
- Shade Orange category
- Scarlet category
- Red category
- Carmine category
Hybrid pigments are also a type of DPP Pigments. These pigments are
produced by crystallizing Pyrroles with Quinacridones.
Structure of DPP Pigments
Pyrroles have also been crystallized with quinacridones to produce
hybrid pigments (PR N/A). The differences in colors in different kinds
of DPP Pigments are due to the differences in the atom hanging
symmetrically on the both hands of the molecules.
DPP Pigments have a wide range of applications. This
is because of the large range of available colors of these pigments. The
large range of colors are possible due to the simple selection of
different constituents on the phenyl rings. Through derivatisation
methods, these pigments can be converted into soluble form. Thus, these
pigments can be applied in the soluble form. Then, the derivatizing
group is removed from the soluble from of these pigments. After removing
the derivatizing group from the solution, the desired pigments are left
there. This method increases the applicability of these DPP Pigments.
DPP Pigments are high performance pigments. These are mostly used for
highest quality automotive coating.
