24、rsedlatex particles at that surface.DISCUSSIONThe deposition rate of the latex is controlled by the rateof surface solubilization.

(White, grayand black colors possess no hue). E284DISCUSSIONThe short end of

38、 the spectrum is violet, with purple bydefinition being a nonspectral combination of red and violet.
