Embodiment I

[0162] A radiation curable base composition was first formed by mixing the various components shown in Table 1 .

[0163] Table 1

[0164] components Amount (% by weight of total composition) Ethoxy diacrylate monomer 1 42.85 Aliphatic Urethane Diacrylate Oligomer 2 25.25 pentaerythritol tetraacrylate 12.55 1,6-Hexanediol diacrylate 1.68 Isobornyl Acrylate 3.88 Phenoxyethyl acrylate 3.88 Butylated hydroxytoluene 0.52 Benzophenone 8.33 2-Methyl-1-(4-(methylthio)-phenyl)-2-(4-morpholinyl)-1-propanone 1.04

[0165] 1 CN120, (Sartomer)

[0166] 2 Ebecryl 264, (Radcure)

[0167] 96% of this base composition was then mixed with 4% of CGI 819 (Ciba Geigy) to form a radiation curable composition. 88% by weight of the radiation curable composition was mixed with 9% by weight of blue pigment, 3% by weight of white pigment to form a radiation curable ink composition.

Embodiment II and III， and comparative Embodiment A

[0178] Two radiation curable carrier systems were first formed by mixing the various components shown in Tables 2 and 3.

[0179] Table 2

[0180] carrier system AA

[0181] components Amount (% of total system weight) Ethoxyacrylate Monomer 33.9 Aliphatic Urethane Diacrylate Oligomer 19.9 pentaerythritol tetraacrylate 9.95 Isobornyl Acrylate 3.06 Phenoxyethyl acrylate 3.06 1,6-Hexanediol diacrylate 13.64 Silicone diacrylate 1.14 2,6-di-tert-butyl-methyl-phenol 0.57 2-Methyl-1-(4-(methylthio)phenyl)-2-(4-morpholinyl)-1-propanone 4.55 Improve ink curing speed photoinitiator CGI819 1.14 Acrylated benzophenone 9.09

Embodiment IV

[0192] Ink coating compositions were prepared by mixing the following components:

[0193] Component % (by weight of the total composition)

[0194] Ebecryl 3700 (ethoxy acrylate) 51.0

[0195] Alkoxylated aliphatic diacrylate 30.0

[0196] Irgacure 819 1 1.0

[0197] Irgacure 907 3.0

[0198] Benzophenone 4.0

[0199] Blue Pigment (Penn Color) 1.5

[0200] BYK 333 2 0.5

[0201] 1 Irgacure 819 by Ciba Geigy

[0202] 2 BYK 333 is a polyether-modified dimethyl polysiloxane.

Abstract

Provided is ribbon assembly having the functional capability of providing break-out of color coded coated glass fibers from said ribbon assembly. The monomers, oligomers and photoinitiator for forming the color coating on the optical glass fibers contained in the ribbon assembly have been selected to provide an average percentage of reacted acrylate unsaturation which provides a level of adhesion between a matrix material and a colored coating that is less than a level of adhesion between the colored coating and the coated optical glass fiber to provide break-out of the color coded optical glass fiber from said ribbon assembly. Also provided are colored coating compositions adapted to form colored coatings suitable for use on optical glass fibers containing in the ribbon assembly.

Description

[0001] This application is a divisional application of the parent application whose application number is CN98806630.0. The filing date of the parent application is May 6, 1998; the title of the invention is "radiation curable ink composition". technical field [0002] The present invention relates to radiation curable ink compositions, methods of making coated and colored optical glass fibers, coated and colored optical glass fibers and ribbon assemblies comprising such coated and colored optical glass fibers. Background technique [0003] Optical glass fibers are typically coated with two superimposed radiation curable coatings, which together form the primary coating. The coating that is in direct contact with the glass is called the inner main coating, while the covering layer is called the outer main coating. An inner primary coat may also be referred to as a primary coat, and an outer primary coat may be referred to as a secondary coat. These two definitions are used...
