Definitions
- the present invention relates to a paste composition for an optical waveguide. More specifically, the present invention relates to an optical waveguide paste composition in which barium sulfate particles are dispersed in an organic material, and an optical waveguide using the same.
- a paste composition in which inorganic particles are dispersed in an organic substance such as a resin, and a cured product obtained by curing the paste composition include a coating material for printing, a lubricant, a cosmetic, an adhesive, a release agent, Alternatively, it is widely used as a constituent material for displays and mounting substrates.
- thermo-mechanical properties, electromagnetic properties, optical properties, etc. cannot be obtained with resin alone! / In such cases, the content can be reduced to reduce production costs.
- inorganic particles to be dispersed have a particle size as small as several tens to several nanometers. Attempts are being made in each technical field.
- inorganic particles with a particle diameter of several tens to several nanometers are used as resin to suppress changes in the refractive index and dimensions of the optical waveguide material due to temperature and to ensure the light transmission of the material. Technology to disperse them is being studied.
- inorganic particles As one method of dispersing inorganic particles in a resin, there is a method of first producing a dispersion in which inorganic particles are well dispersed in an organic solvent, and then mixing the dispersion and the resin.
- Commercially available inorganic particles with an average particle size of several tens to several nanometers are powder-like particles with an average particle size of several tens of micrometers (primary particles) moderately aggregated (primary particles) ( Often provided as secondary particles). Therefore, in order to produce a dispersion of inorganic particles having an average particle size of several tens to several nanometers, agglomeration of these secondary particles in an organic solvent is loosened to produce a dispersion in which primary particles are stably dispersed.
- the average particle diameter of the primary particles is smaller than 50 nm! /, The surface area relative to the particle volume Since the ratio is very large, the frequency of once re-aggregating particles is increased, and the power to advance dispersion is difficult.
- an organic substance called a dispersant having a functional group at the terminal is added, the functional group of the dispersant is coordinated on the surface of the inorganic particles, and the primary particles are prevented from approaching each other.
- a method for suppressing re-aggregation of particles and improving dispersibility is disclosed. As an example of these
- a nickel colloid solution containing nickel colloid particles having an average particle diameter of 20 to 40 nm, a nonpolar polymer pigment dispersant and an organic solvent has been proposed.

- Patent Document 1 A nickel colloid solution containing nickel colloid particles having an average particle diameter of 20 to 40 nm, a nonpolar polymer pigment dispersant and an organic solvent has been proposed.
- Patent Document 2 A method of dispersing barium sulfate particles in an organic solvent using a dispersant.
- a paste composition is produced by mixing a dispersion of inorganic particles using a conventionally known dispersant and a resin, followed by curing the lever to obtain a cured product in which inorganic particles are dispersed.
- the resin curing reaction by light irradiation or heating may be insufficient as compared with the case where inorganic particles are not used. For this reason, the thermomechanical characteristics of the obtained cured product may be deteriorated.
- the composition elutes during development due to insufficient curing of the exposed area, resulting in a pattern shape. May become unclear, or the solubility of unexposed areas may be low, resulting in a paste composition residue during development. Therefore, the optical propagation loss of an optical waveguide manufactured by a photolithography method may increase.
- the dispersibility of pigments depends on whether the pigments used are organic or inorganic, and even if the same inorganic pigments are not the same, for example, with the barium sulfate particles.
- the surface potential and surface smoothness of alumina particles differ greatly, so that the additive power that has the effect of increasing the dispersibility of one side may reduce the dispersibility of the other.
- Patent Document 3 only describes that an inorganic pigment may be used, and as described above, a specific disclosure of the type of inorganic pigment that affects dispersibility has been made. Not in.

- Paste compositions having the compositions shown in Tables 32 to 33 were produced in the same manner as in Example 1, and a cured product for evaluating physical properties and an optical waveguide were produced using the paste composition.
- the evaluation results are shown in Tables 32-33. Indicated.
- the obtained cured product was insufficiently polymerized and could not be evaluated for its soft refractive index and linear expansion coefficient.
- the unexposed portion turned white during development when manufacturing the optical waveguide, and could not be removed by the immersion time of 5 minutes, but the unexposed portion was removed by shaking the substrate for 20 minutes. A thin film residue was present on the surface of the unexposed substrate.
- the optical waveguide pattern in the exposed area was a gentle mountain shape. Attempts to measure the light propagation loss The power loss was too large and the transmitted light intensity was below the detection limit.
- Paste compositions having the compositions shown in Tables 32 to 33 were produced in the same manner as in Example 1, and a cured product for evaluating physical properties and an optical waveguide were produced using the paste composition.
- the evaluation results are shown in Tables 32-33. Both the temperature dependence of the refractive index and the linear expansion coefficient were large.
- the unexposed area turned white during development when producing the optical waveguide, and a film with a thickness of several rn remained in the unexposed area even after rocking for 20 minutes in the developer.
- the force that attempted to measure the optical propagation loss, the power was too large and the propagation light intensity was below the detection limit, and the force was not measurable.
- Paste compositions having the compositions shown in Tables 32 to 33 were produced in the same manner as in Example 1, and a cured product for evaluating physical properties and an optical waveguide were produced using the paste composition. The evaluation results are shown in Tables 32-33.
- FIG.2 Schematic diagram showing the structure of a slab optical waveguide Industrial applicability
- the optical waveguide paste composition of the present invention is used for information transmission between LSIs in a wiring board used for information equipment that performs high-speed signal transmission such as a personal computer, a hard disk recorder, a DV D recorder, a game machine, and a mobile phone. It can be suitably used for an optical wiring that performs the above. Explanation of symbols
