Production of Colored Pigments with Amorphous Arrays of Black and White Colloidal Particles

Sprayed: Pigments with various angle‐independent colors were prepared by a spray method (see picture), which is a remarkably simple method using submicrometer‐sized silica particles and carbon black. The use of a polyelectrolyte that adheres to the particles can stabilize the structure of the colloi...

Summary:Sprayed: Pigments with various angle‐independent colors were prepared by a spray method (see picture), which is a remarkably simple method using submicrometer‐sized silica particles and carbon black. The use of a polyelectrolyte that adheres to the particles can stabilize the structure of the colloidal amorphous arrays to create highly stressable, nonfading pigments.
