Specifications

Where PR 53:1 excels — and where to check carefully

PR 53:1 is a barium lake monoazo delivering a warm, yellowish-red shade with good flow properties, widely specified in offset, NC, and PP inks for packaging and decorative paints. As a barium-containing lake, it is best suited to indoor applications — verify lightfastness for any use with prolonged UV exposure, and check applicable toy-safety or food-contact migration limits (e.g. EN 71-3) before specifying for children’s products or food-contact packaging.
