Pigment Red 49:2
Pigment Red 49:2 is a calcium-lake Lithol red, distinct from the barium PR49:1 pigment. Commercial grades give a bluish-red shade and are used primarily in water-based inks. Color strength, transparency and ink rheology should be compared within the same vehicle.

PRODUCT PROFILE
P.R.49:2Pigment Red 49:2 — grade profile
Pigment Red 49:2 (P.R.49:2) is a monoazo calcium-lake pigment for Printing inks. Compare shade, tinting strength, dispersion and processing stability in the customer’s actual resin or binder rather than relying on one universal value.
Published screening data includes published heat reference 160 °C, light fastness 5/8 and oil absorption 40–55 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Water-based inks.
Selection focus
At equal loading, compare shade, tinting strength, dispersion and resin or binder compatibility, then confirm the required fastness under the final process conditions.
