Product Description of Pigment Red 184:

Pigment Red 184 is similar to CI Pigment Red 146 in terms of shade, application performance and chemical structure. It is a modified product of CI Pigment Red 146. It is mainly used for printing inks. Its samples are resistant to soap, paraffin, dibutyl phthalate, Toluene, etc.; light fastness is one level higher than CI Pigment Red 57:1; excellent solvent resistance makes it suitable for all kinds of printing inks, such as packaging printing inks, flexographic printing inks and metal decorative printing inks, and the heat stability is 170℃/10min

Pigment Red 184 is a blue shade, semi-transparent Naphthol AS pigment. It meets the requirements for the EUropean Scale for Process printing. It exhibits food allround fastness properties and is an alternative for Pigment Red 57:1 pigments, if their fastness properties are not good enough. Recommended for paste inks as well as for solvent- and water-based packaging gravure and flexographic printing inks.
