HP RED 2442 / PIGMENT RED 22

Pigment Red 22

P.R.22 affords yellowish shades of red. Its main market is in textile printing, but it is also used throughout the graphics field, such as in offset and gravure printing, especially in NC-based inks. P.R.22 is advantageous where soap and alkali resistance are required. A pigment with high tinctorial strength, it is somewhat lighter than P.R.9 in high pigment area concentrations; while at lower pigment area concentrations it is yellower. Compared to P.R.2, P.R.22 is distinctly yellower and less lightfast; this tendency is even more pronounced in comparison with P.R.112.

The paint industry employs P.R.22 in air drying systems, in emulsion paints, and occasionally in industrial finishes; Again, P.R.22 is much less lightfast in these media than P.R.112. Areas of application include paper mass and surface coloration, colored pencils, artists colors, and other purposes.
