Abstract: Radiation curable compositions suitable for use a optical fiber ribbon matrix materials are provided which have at least two non-silicone urethane(meth)acrylate oligomers, one or more multifunctional diluents and one or more photoinitiators, wherein each of the non-silicone urethane(meth)acrylate oligomers has a number average molecular weight of about 200 or more, but less than about 6000, and the polydispersity index (PDI) of the urethane(meth)acrylate oligomers is from 2:1 to 30:1. The matrix material may be coated and cured on a plurality of optical fibers so as to form an optical fiber ribbon assembly.

Abstract: The present invention relates to a coated optical fiber comprising a glass optical fiber with a single protective coating or a combination of an inner and an outer primary coating applied thereon and optionally with a colored coating subsequently applied thereon wherein the inner primary coating or at least a portion of the single coating is prepared from a radiation curable composition which when cured as a capillary film with a 100W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 54% after exposure to a dose of about 4.4 mJ/cm2 or wherein the outer primary coating is prepared from a radiation curable composition which when cured as a capillary film with a 100 W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 56% after exposure to a dose of about 4.4 mJ/cm2. The invention further relates to a radiation curable composition having a high cure speed.

Abstract: The present invention relates to radiation-curable compositions that after cure release fully from a matrix material while maintaining other desirable qualities of radiation-cured compositions. These radiation-curable compositions include at least one radiation-curable oligomer and at least one oligomeric photoinitiator. These compositions can be formulated, for example, to serve as protective coatings for substrates manufactured from a wide variety of including glass, plastic, ceramic, metal and wood. The compositions of the present invention are preferably designed for use as an optical fiber coating (including inner primary and, colored or uncolored, secondary coatings as well as other coatings which include inks, matrix materials and the like) or related optical fiber protective materials.
