C.I. pigment red 48:2

C.I. Pigment Red 48:2 (CAS 7023-61-2) is a calcium-based azo pigment also known as Fast Red F5R, Ponolith Red Y, Eljon Rubine 2BS, and C.I. 15865:2. It carries no E-code designation and belongs to the monoazo laked pigment class, where a calcium salt complex provides the insoluble, colour-stable form used in industrial applications.

In plastics and packaging printing, PR 48:2 delivers a bluish-red hue through its calcium lake structure, which anchors the chromophore to substrates and resists bleed into adjacent materials. It is also used in coatings and adhesive systems, where its surface-active character supports pigment dispersion and substrate wetting during formulation.

PR 48:2 is supplied under REACH compliance and is available in standard powder grades suited to solvent-based, water-based, and resin systems. Packaging is typically offered in fibre drums or multi-wall bags; buyers should confirm grade specifications for end-use regulatory requirements in their target markets.
