Title
(EN) PHOTOCURABLE PIGMENTED SECONDARY OPTICAL FIBER COATINGS
(FR) COUCHES DE FIBRE OPTIQUES SECONDAIRES COLOREES ET PHOTODURCISSABLES
Abstract
(EN)
A liquid pigmented (meth)acrylate-functional photocurable coating composition adapted for the secondary coating of optical glass fiber is disclosed. This photocurable composition has a pigment content which is sufficient to provide a coloration which can be distinguished from other colors and in the absence of a significant excess of said pigment, the particles of the pigment have a size of less than about 1 micron, and an acyl phosphine oxide photoinitiator is used to obtain a rapid photocure despite the presence of the pigment, the composition's normal thickness when used for optical fiber coating, and the fine particle size of the pigment.
(FR)
Une composition de couche liquide, colorée, photodurcissable et à fonction métacrylate adaptée à l'enrobage secondaire de fibres de verre optiques. Cette composition photodurcissable a une teneur en pigment suffisante pour fournir une coloration qui peut être distinguée d'autres couleurs, et dans l'absence d'un excédent important dudit pigment, les particules du pigment ont une taille de moins d'un micromillimètre environ, et un photoinitiateur en oxyde de phosphine d'acyle est utilisé afin d'obtenir un photodurcissement rapide en dépit de la présence du pigment, de l'épaisseur normale de la composition lorsqu'elle est utilisée à des fins de couchage de fibre optique, et de la taille des particules fines du pigment.
