The keto pyrrolo pyrrole
The keto pyrrolo pyrrole (diketo-pyrrolo-pyrrole, diketo pyrrolo pyrrole, diketopyrrolopyrrole) is an organic compound. The compound which replaced a part of the structure that I advocated here is used as a heterocycle color having a symmetric chromophoric group. I was developed in the early 1980s. I am red from orange. In the application field in particular, I name a the keto pyrrolo pyrrole color except pure the keto pyrrolo pyrrole generally with the keto pyrrolo pyrrole mainly.
I can operate transparency by controlling particle diameter. Blue is strong in the thing having a small particle diameter and the transparency is relatively high, but still is slightly opaque. Pigment Red 254, Pigment Red 255, Pigment Red 264, Pigment Orange 71, the Pigment Orange 73rd class are listed in Colour Index. Each these is clear, and it is solid.
The mixed crystal with the Quinacridone is studied and circulates in the market. Quinacridone - pyrrole is available as paint in the place at hand. The hue of Pigment Red 254 and Pigment Red 255 is creamy red like R of practical RGB. Pigment Red 254 is adopted to a red color filter well. I am suitable for this use than Pigment Red 177 adopted well before. What is used secondarily then such as Pigment Orange 71 or Pigment Yellow 139 is a color of the creamy more. Creamy is considerably from Pigment Red 254 strong, and Pigment Red 255 has slightly low chroma.
