HP RED 2537 / PIGMENT RED 53:1

Pigment Red 53:1 For solvent based printing inks

P.R.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, which is the DIN 16 539 standard magenta for three and four color printing.

P.R.53:1 is a comparatively strong and brilliant pigment within its range of shades. In print, P.R.53:1 shows good fastness to a series of organic solvents: it is almost completely stable to the DIN 16 524 solvent mixture. The pigment is entirely fast to clear lacquer coatings. As a result of the chemical constitution of the pigment,the prints are sensitive to alkali and acids.

P.R.53:1, which is used in large volume in aqueous flexographic printing inks,may present problems in terms of storage stability.
