Pigment red 48:2 for Packaging gravure Inks The two types are used in almost exactly the same areas of application. P.R.48:2 is also found in printing inks, especially for packaging inks based on NC. Resinated grades are more transparent and bronze less in print. The viscosity of aqueous printing inks often rapidly increases during storage, a problem which may lead to thickening.

Pigment red 48:2 for Plastics P.R.48:2 is also used in plastics, where it affords good tinctorial strength. Such colorations are heat stable up to 230°C for 5 minutes, but higher temperatures shift the color towards bluer, duller shades. At higher temperature, on the other hand, more reduced colorations (1/9 SD) shift the shade to yellower and cleaner hues. P.R.48:2 is used to an appreciable extent in LDPE, in which it is more lightfast than corresponding P.R.48:1 samples: the difference is about 2 1/2 steps on the Blue Scale. Incorporated in plasticized PVC, P.R.48:2 is not entirely 2.7.2 BONA Pigment Lakes 327 bleed resistant. The pigment may be used in PP spin dyeing only if polymers with a low melting point are used. In order to ensure sufficient light fastness, the pigment is used to advantage in deep shades, i.e., at high concentration.
