What Are Pyrrolo Pyrrolidone DPP Pigments

Pyrrolo pyrrolidinedione DPP pigment is a new class of high performance organic pigment researched and developed by Ciba Refinement Company of Switzerland, and the introduction of this series of pigment varieties is regarded as a milestone in the history of the development of organic pigments.DPP pigment has the characteristics of high coloring power and bright color, and it also has the advantages of good fluidity in application medium, good fastness to sunlight, fastness to light and good heat resistance, so it can be comparable with the high performance pigments such as quinacridone pigment, perylene pigment and benzimidazolone pigment. Therefore, they are comparable to quinacridone pigments, perylene pigments, benzimidazolone pigments and other high-performance pigments. Below, the manufacturer of pigment orange 13 introduces several commonly used pyrrolo-pyrrolidinedione DPP pigment varieties and their application properties.

Pigment Orange 73
Pigment Orange 73 is a brilliant orange color with high tinting strength. Pigment Orange 73 has excellent heat and weathering resistance. Pigment Orange 73 can be applied to soft (hard) PVC, polyethylene, polypropylene, polystyrene plastics, as well as to engineering plastics such as ABS and nylon.

Pigment Red 254
Pigment Red 254 is the first commercialized variety of DPP developed by Ciba Precision Chemicals, Switzerland. It is a brilliant red color with excellent transparency and high saturation.

Pigment Red 264
Pigment Red 264 is a brilliant bluish red, with high transparency and coloring power, excellent heat resistance and sun resistance. Transparent soft PVC containing Pigment Red 264 (0.1 ~ 0.5%) and soft PVC containing Pigment Red 264 (0.2%) and titanium dioxide (0.5% ~ -2%) can withstand temperatures up to 200C/1omin, A. There is no change in the color and light. Pigment Red 264 is also suitable for engineering plastics such as ABS and nylon.

Compared with inorganic pigments, organic pigments are inferior in terms of covering power, sunlight resistance and thermal stability, but high-performance pyrrolo pyrrolidinedione DPP organic pigments make up for the shortcomings in these aspects, not only do they have very high coloring power, bright colors and a wide range of available shades, but also have color fastness performance comparable to that of inorganic pigments.
