PRODUCT PROFILE
P.O.5Pigment Orange 5 — grade profile
Pigment Orange 5 (P.O.5) is a monoazo naphthol pigment for Coatings & paint, 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 6/8 and oil absorption 35 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Industrial coatings, Pigment textile printing, Water-based inks and NC inks; Water-based decorative coatings and Offset inks are listed for evaluation.
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.
