This research shows that pigment sizing improved the tensile strength of decorative base paper. Both surface sizing and pigment sizing had a more obvious effect on the reduction of roughness. The water absorption height was decreased by surface sizing, but increased with higher proportion of silica due to the reduction of sealing of sizing. Both pigment sizing and surface sizing improve color.
Beautician, a red pigment, can be obtained in the vacuole of beet root cells, and is commonly seed industrially as red food coloratura or ink. In exploring the permeability of a beetroot membrane which contains a colored pigment, additional research was conducted regarding light and the optical spectrum. The visible spectrum of light is the portion of the electromagnetic spectrum which is.
