The Commonly Used Pigment Red 53:1 In The Printing Inks

Pigment Red 53:1, a barium lake, is one of the most important red pigments for use in printing inks. Its scarlet shade is much yellower than that of P.R.57:1. It is a comparatively strong and brilliant pigment within its range of shades. However, Yellowish types of P.R.53:1 are usually less strong than bluish ones. In print, P.R.53:1 shows good fastness to a series of organic solvents. P.R.53:1, which is used in large volume in aqueous flexographic printing inks, may present problems in terms of storage stability.
