Definitions

  • the present invention relates to composite agglomerated resin particles. Specifically, the present invention relates to composite agglomerated resin particles excellent in light diffusion performance, a method for producing the same, and various compositions containing the particles.
  • particles less than 100 nm contained in the particle may impede the transmission of light and reduce the transmittance of light irradiated from a backlight or the like. Further, in such particles, additives such as surfactants used in the production process remain, and thus there may be problems such as deterioration of physical properties and coloring during film molding or long-term use.
  • the raw material aggregated particles are 90 to 100% by weight of a vinyl monomer having a solubility in water of less than 3% by weight based on the total weight of the monomer, and 0.25 to 3 of a water-soluble polymerization initiator.
  • the composite agglomerated resin particle according to any one of [1] to [6], wherein the composite agglomerated resin particle is formed by polymerization in water using a weight percent.
  • the composite agglomerated resin particles of the present invention have a sparse agglomerated structure, and voids exist inside the particles, so that the particle density is low and the interface area per unit weight of the particles is large. Therefore, a higher light diffusion effect can be obtained. Further, since the particle shape is indefinite, it is expected to have light diffusion performance that cannot be obtained with conventional resin particles. In addition, since the fine resin particles aggregated with the vinyl polymer are integrated, the aggregated state can be maintained even in an aqueous solvent or an organic solvent. Even if it exists, the coating film which expresses the desired frosting effect can be obtained, it is hard to generate
  • the composite agglomerated resin particle of the present invention is an agglomerated resin particle in which a vinyl polymer is compounded with raw material agglomerated particles obtained by agglomerating fine resin particles, and the fine resin present in at least a surface layer portion of the raw material agglomerated particles
  • the particles are characterized by being integrated with the vinyl polymer.
  • the “integrated state” is a state in which the fine resin particles are not simply agglomerated but adhered to each other by the vinyl polymer, and the organic resin is in an aqueous solvent. In any of the solvents, the aggregated state can be maintained and the primary particles are not formed.
  • the “combined state” means a state in which the vinyl polymer is adhered to the raw material agglomerated particles by immersing the raw material agglomerated particles in a solution of the vinyl polymer, Examples include a state obtained by polymerizing a vinyl monomer that is a raw material for a vinyl polymer in an aqueous dispersion of raw material aggregated particles.
  • the shape of the composite agglomerated resin particles of the present invention is preferably indefinite.
  • the shape of the composite aggregated resin particles is not the detailed shape of the composite aggregated resin particles, but the overall shape.
  • indefinite shape means a state in which the shape of each composite aggregated resin particle varies. In such a state, most of the particles have a shape that is difficult to say spherical, and has an unevenness around the image of the particles viewed from one direction, that is, the particle projection image.
  • the composite agglomerated resin particles of the present invention since the fine resin particles are integrated with the vinyl polymer as described above, the composite agglomerated resin particles are easily handled even in a dry state. And fine particles do not scatter. In addition, in water-based solvents and organic solvents, it does not re-disperse to fine particle units, so when added to water-based paints or solvent-based paints to form a film, the agglomerated state is maintained. On the surface of the composite agglomerated resin particles, surfaces having various angles are present without being unevenly distributed, and an effect of scattering incident light from any direction without any spots can be obtained.
