摘要:
Disclosed is a photopolymerizable resin composition. The photopolymerizable resin composition includes 40 to 80% by weight of a photopolymerizable urethane (meth)acrylate oligomer, 10 to 40% by weight of a low-viscosity multifunctional urethane acrylate oligomer, and 1 to 10% by weight of a photoinitiator. The photopolymerizable resin composition is cured by UV light to form a film whose shrinkage and expansion rates after immersion in hot water are low, leading to minimal changes in tensile strength and adhesive strength before and after water immersion. Further disclosed is an optical fiber using the photopolymerizable resin composition. The optical fiber undergoes minimal change in strip force before and after immersion in hot water.

Disclosed is a photocurable coating composition for an optical fiber. The photocurable coating composition can be used to produce an optical fiber having a low polarization mode dispersion (PMD) even by a non-spinning process. The photocurable coating composition includes a photopolymerizable urethane acrylate oligomer, a reactive monomer, a photoinitiator and an amine additive. Further disclosed is an optical fiber using the photocurable coating composition. The optical fiber has a polarization mode dispersion (PMD) of 0.1 ps/√km or less when produced by a non-spinning process.

The present invention relates to a conductive paste composition. The conductive paste composition includes a binder resin including a urethane group present in a main chain or a side chain, especially a binder resin formed from isocyanate and a polymer with at least one hydroxyl group, a fine powder, a glass frit, and a solvent. The conductive paste composition can have a superior physical property, improve productivity and an environmental problem by reducing waste fluid such as aqueous alkaline solution, and form a fine pattern having an improved structure. Accordingly, the paste composition is especially useful for a paste for gravure offset printing.

摘要:
The inventive UV-curable aqueous coating composition is characterized by using a UV-curable aqueous emulsion obtained by urethane reaction with a mixture comprising a poly-carbonate polyol or polyester polyol; an isocyanate compound; a urethane-reactive carboxylic acid; a UV-curable acrylic oligomer having 2 to 9 functional acrylate groups; a UV- curable acrylic monomer; and a urethane-reactive acrylate without an organic solvent. The inventive aqueous composition provides good environmental acceptability and satisfactory film properties comparable to those of the prior oily UV-curable coating composition and thereofore, it is useful for coating various plastics.
摘要:
A method for manufacturing a flat panel display device, including at least one unit discharge cell, discharge space for the unit discharge cells being located between an upper and a lower substrate that form a discharge space therebetween and disposed facing each other, comprising the steps of: (a) forming multiple electrodes on a reference substrate; (b) cutting the reference substrate into a plurality of strip-shaped substrates, each including at least one electrode; and (c) inserting the strip-shaped substrates between the upper and the lower substrates to form partition members dividing the discharge space into unit discharge cells.
