PRODUCT PROFILE
P.R.22Pigment Red 22 — grade profile
Pigment Red 22 (P.R.22) is a naphthol pigment for Printing inks and Textiles & fibers. 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 140 °C, light fastness 5/8 and oil absorption 45–55 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Water-based inks and Pigment textile printing.
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.
