C.I.NO.PR49:2 2496 SuperFast Red RB

Red 49:2 2496 SuperFast Red RB

Both the barium lake P.R.49:1 and the calcium lake P.R.49:2 resemble Lake Red C pigments (P.R.53:1) in terms of fastness to organic solvents, to alkali and acid, and to fastness in application. However, P.R.49 grades are much less heat stable, which narrows their applicability in plastics. Areas of application, especially in the USA, include elastomers, to a lesser extent also inexpensive industrial paints, air drying and nitro paints. Their main market, however, is in printing inks.
