Embodiment 1

[0071] 86 parts by weight of the oligomer prepared in Preparation 1, 10 parts by weight of Light EsterFM-108 (Kongyoung Co., Korea), 2.5 parts by weight of Irgacure#184 (CibageigeCo.), 0.5 parts by weight of Byk 375 (manufactured by BYK-Chemie Co.) and 1 part by weight of Irganox 1010 (manufactured by Cibageige Co.) were added to the reactor and stirred at about 25 ° C to prepare a photopolymerizable package for optical fibers or waveguides layer resin composition.

Embodiment 2-9

[0075] Except for substituting the oligomers prepared in Preparations 2 to 9 for the oligomers prepared in Preparation 1, the procedure of Example 1 was repeated to prepare eight photopolymerizable cladding resin compositions.

Embodiment 10

[0077] Except that Light Ester HDDA (Kongyoung Co., Korea) was used instead of Light Ester FM-108 as the photopolymerizable monomer (B), the procedure of Example 1 was repeated to prepare a photopolymerizable cladding resin composition.

Abstract

The present invention relates to a UV curable clad resin composition for optical fiber or waveguide comprising: (A) a photopolymerizable acrylate oligomer derived from the mixture composed of a polyol copolymer, an acid anhydride, an acrylate alcohol, a condensation polymerization catalyst and a polymerization inhibitor, (B) a photopolymerizable monomer, (C) a photopolymerization initiator, and (D) a leveling or antifoaming agent. The inventive composition minimizes optical loss and has a controllable low refractive index in the range of 1.35 to 1.46.

Description

field of invention [0001] The present invention relates to an ultraviolet curable resin composition for optical fibers or waveguides, which exhibits low light loss and low refractive index. Background of the invention [0002] An optical fiber consisting of a core and a cladding coated on the core is used as a waveguide. The core with high light transmittance is made of glass or plastic, and the cladding is made of glass or resin with a lower refractive index than the core material. Flexible plastic-clad optical fibers with relatively thick cores have been developed for indoor or short-haul applications. In addition, optical fibers with double cladding, the outer layer having a lower refractive index than the inner layer, have also been developed. [0003] Various thermoplastic resin compositions have been used for optical fiber coatings, but at high curing temperatures, the use of these thermoplastic resins requires relatively long curing times, which results in some ther...
