Pigment Blue 15:1
Pigment Blue 15:1 is a stabilized alpha-form phthalocyanine blue, usually positioned on the reddish side of the PB15 range. Grades are available for inks, coatings, plastics and textile printing. The exact composition and CAS identity should follow the grade SDS, especially for chlorinated or otherwise modified forms.

PRODUCT PROFILE
P.B.15:1Pigment Blue 15:1 — grade profile
Pigment Blue 15:1 (P.B.15:1) is a stabilized alpha-form phthalocyanine pigment for Plastics & masterbatch, Coatings & paint 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 260 °C, light fastness 8/8 and oil absorption 45–55 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), ABS, PP fiber, Water-based decorative coatings and Pigment textile printing; Polystyrene (PS), PET, PET fiber and Industrial coatings 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.
