Product detail
Three tables of phthalo blue and green, one grade per job.
The brochure sorts every grade by end use and lists the equivalent multinational standard, the Choksi standard, the system it is meant for and its character: shade direction, strength, gloss, dispersibility, flow, crystallisation and heat.

Where it goes
Where phthalo blue and green go to work.
- Offset, heat set, cold set and water-based printing inks

- Paints, industrial coatings and powder coating
- PP, PE, ABS masterbatch and engineering plastics up to 350°C
01What is phthalo blue used for?
Printing inks, paints, coatings and plastics. It is the standard clean blue: high strength, light fastness 7 to 8 and heat resistance from 200°C to 350°C depending on the grade. In our range it goes into offset, water based and solvent inks, industrial and powder coatings, and PP, PE and ABS masterbatch.
02Is phthalocyanine blue the same as phthalo blue?
Same pigment, shorter name. Both mean copper phthalocyanine, C.I. Pigment Blue 15. The number after the colon is what matters commercially: 15:0 alpha, 15:1 stabilized alpha, 15:3 beta green shade, 15:4 non-crystallizing beta.
03What is phthalo blue made of?
Copper phthalocyanine, built from a phthalic derivative, urea and a copper salt. The crystal form is what separates the grades, and it decides shade direction, crystallization resistance and heat stability.
04Which phthalo blue is best?
The one that matches your system. 15:3 HD-810 for water based inks and paints where you want a green shade with gloss. 15:4 for inks and coatings that must not crystallize or flocculate. 15:1 RC-2721 for plastics at 280°C, 15:0 HD-6850P for EVA, PBT, PA and PC at 220°C.
05What is the HS code for pigment blue 15 3?
3204.17 covers it, as a synthetic organic pigment and preparations based on it. Your broker adds the local suffix. Give the pigment team the grade and the destination port and the exact code goes on the proforma.
