Abstract
The invention relates to a method in which machine-finished paper or paper under manufacture in, e.g., a fourdrinier machine, is coated on both sides thereof with a protective coating containing materials or substances which will reflect ultraviolet light and also absorb such light. Provided on top of the protective coating is a pigment coating which contains luminescent materials, such that the remitted light will obtain a wavelength composition such that the human eye will discern the paper as preferably white.
