C.I.PR48:2 2490 SuperFast Red 2XL Pigment red 48:2 for Packaging Inks

The two types are used in almost exactly the same areas of application. P.R.48:2 is also found in printing inks, especially for packaging inks based on NC. Resinated grades are more transparent and bronze less in print. The viscosity of aqueous printing inks often rapidly increases during storage, a problem which may lead to thickening.

It is inferior to P.R.48:1 in terms of sterilization fastness in print, and the same is true for its fastness to soaps. On the other hand, P.R.48:2 is distinctly more lightfast than P.R.48:1. Exposed 1/1 SD P.R.48:2 letterpress proof prints, for instance, equal step 4–5 on the Blue Scale, while corresponding P.R.48:1 specimens only reach step 3-4.
