C.I.PR4 2485 SuperFast Red R

2485 SuperFast Red R
PIGMENT RED 4 C.I. PR4

P.R.4 affords a yellowish red shade, somewhere between the more yellowish P.O.5 and the more bluish P.R.3. Tinctorially, P.R.4 is the weakest of the three. In order to formulate equal depth of shade in an air drying alkyd system, three equivalents of TiO2 are necessary per equivalent of P.R.4; while P.O.5 and P.R.3 require 5 and 6 parts of TiO2, respectively, per equivalent of organic pigment; provided all other parameters are equal. Full shades exhibit good lightfastness (step 6), but darken somewhat upon exposure.

In the printing inks field, P.R.4 is employed as a clean, yellowish red colorant for purposes where no solvent fastness is required.

Application in rubber blends, which used to be an important market for P.R.4, has suffered from increasingly stringent requirements.

P.R.4 is also used in specialized applications. The pigment lends color to cleaning agents and detergents, including shoe polish and floor polish, office articles and artists’ colors, including colored pencils, wax crayons for schools and artists, and pastel chalks, and to low price watercolors. It is also used in decorative cosmetics, for which types are available which meet the legal requirements.
