The present invention relates to a photocurable coating composition for forming a low refractive layer, a method for preparing an antireflection film using the photocurable coating composition, and an anti-reflective film prepared by using the photocurable coating composition. According to the present invention, a low refractive layer is formed of a photocurable coating composition containing two or more types of photo-polymerizable compounds, a photoinitiator, surface-treated hollow inorganic nanoparticles, and surface-treated solid inorganic nanoparticles.

A pelletized thermoplastic road marking material is provided in which glass dust rather than calcium carbonate is used as the filler. Such glass dust can account for up to 55 weight % of the final formulation. Glass dust is a readily available and inexpensive byproduct of glass manufacturing which otherwise has little or no commercial value. Use of the glass dust is effective if the thermoplastic composition is prepared in pelletized form and performs comparably to a thermoplastic composition having calcium carbonate filler, while producing a higher yield.

The invention relates to a method for treatment of wood material. In a first treatment step comprises the provision of a solution comprising zinc oxide or titanium(IV) isopropoxide and immersion of the wood material into the solution. After drying of the wood material a second treatment step is following in case of the first solution comprising zinc oxide. The second treatment step comprises the provision of a solution comprising a zinc compound and immersion of the wood material from the first treatment step into the solution followed by drying of the wood material. In a second aspect the invention relates to a wood material characterized by the visibility of the natural appearance of the surface and at least one other property relating to UV resistance, weathering resistance, mechanical resistance or hydrophobic properties.

A dispersion comprising at least metallic copper particles with gelatin provided on the surface thereof, a polymeric dispersant, and an organic solvent. The dispersion is produced by reducing copper oxide in an aqueous solvent in the presence of gelatin having an amine number and an acid number wherein the difference (amine numberacid number) is 0 or less, then subjecting the reaction solution to solid-liquid separation, and then mixing the resultant metallic copper particles with gelatin provided on the surface thereof and a polymeric dispersant having an amine number and an acid number wherein the difference (amine numberacid number) is 0 to 50, into an organic solvent. The dispersion maintains dispersion stability of the metallic copper particles for a long time, is suitable for inkjet printing and spray coating and can be used to make microelectrodes and circuit wiring patterns.
