Title (EN) A METHOD FOR THE MANUFACTURE OF LIGHT-STABLE PAPER FROM MECHANICAL PULP, AND PAPER PRODUCED IN ACCORDANCE WITH THE METHOD
(FR) PROCEDE POUR LA FABRICATION DE PAPIER PHOTOSTABLE A PARTIR DE PATE MECANIQUE, ET PAPIER PRODUIT SELON CE PROCEDE
Abstract: front page image
(EN)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.
(FR)Est décrit un procédé dans lequel du papier fini machine ou du papier en cours de fabrication dans un fourdrinier par exemple, est enduit sur les deux faces d'un revêtement protecteur renfermant des matières ou des substances qui vont réfléchir la lumière ultraviolette et également absorber cette lumière. Le revêtement protecteur présente sur le dessus un revêtement pigmentaire contenant des substances luminescentes, de sorte que la lumière renvoyée va posséder une composition de longueur d'onde telle que l'÷il humain va discerner le papier comme étant de préférence blanc.
