Pigment
Yellow 74 is a significant commercial pigment which is primarily and
extensively used in the coating industries
in water-based, solvent-based based and air-drying paints. It is also used in the
printing ink industry in water-based inks, solvent-based inks, and paste inks.
Monoazo Yellow pigments span the spectral yellow range
from greenish yellow to reddish yellow with good light fastness and good tinting
strength. It has greenish yellow tones
thataremidwaybetweenPigmentYellow3andPigment Yellow 1. The pigment is
considerably stronger than and superior to all comparable monoazo yellow
pigments. Commercially available Pigment Yellow 74 grades with a widerange of
particle sizes, i.e., pigments with specific surface areas between approximately
30and70m2/g, are used primarily in the coating and colorant industry
as well as in the printing ink industry.
They provide brilliant prints, which are brighter and
more transparent than those of other monoazo yellow pigments. In terms of
tinctorial strength, these Pigment Yellow 74 varieties reach the level of the
similarly colored disazo yellow pigments, such as the slightly redder Pigment
Yellow 12.

For some years, the paint industry has progressively
focused on Pigment Yellow 74 with very low specific surface areas of 12 to 20 m2/g
and, as a result, has relatively large particle sizes. These materials have
strong hiding power and could be used as a substitute for Chrome Yellows in
air-drying systems. As a result of favorable pigment rheology, Pigment
Yellow74, concentrations in paints can be increased to
even improve the hiding power without affecting the rheology, i.e., the flow
properties, the ease of processing, or the brilliance of the product. Compared
to transparent types with fine particle sizes, the opaque varieties are less
brilliant, more reddish, and more lightfast and durable. They are also faster
to various organic solvents, but their tendency to migrate is similar.
VOXCO has both the grades of Pigment Yellow 745GSC and Pigment
Yellow 742 GSC.

Mono-azo
yellow is a family of organic pigments. They are mainly used as decorative
and industrial colorants due to their higher tinctorial strength. It has good
rheological properties and is suitable for Decorative Colorant applications. These
pigments are usually transparent and have a slightly greener undertone as
compared to Pigment Yellow 74 2GSC. |
Pigment Yellow 74 2GSC also
comes under the Mono-azo yellow family of organic pigments. They are
primarily used as industrial colorants and in exterior paints due to their
better hiding power. They are used in artistic oil paints, acrylics, and watercolours.
These pigments are usually opaque with redder undertones as compared to Pigment
Yellow 74 5GSC. |
