Abstract
A novel highly diffuse, consistent reflectance, non-thermochromic and desirable and waterproof series of color standards of sintered fluorinated long-chain addition polymer doped with appropriate pigments, and a method of fabricating the same involving packing and compression density control of the pigment/polymer mixture and concentration control of the pigment dopant in the pre-sintering steps.
