Pigment Orange 13, pyrazolone orange, permanent orange G  P.O.13 is pyrazolone orange, comes in semitransparent types with specific surface areas between about 35 and 50 m2/g. P.O.13 is extensively used in the rubber industry, It is coloristically very similar to P.O.34, but generally somewhat yellower. The pigment blooms over a large concentration range and bleeds considerably. At concentrations below ca.0.1%, neither P.O.34 nor 13 are suited for use in rigid PVC.. P.O.13 shows less stability in paints than P.O.34 types of similar particle size. The graphics industry uses P.O.13 to an appreciable extent for packaging printing inks.
