A composition for coating an overhead conductor is disclosed comprising: (i) a reflective agent; (ii) a photocatalytic agent comprising 70 wt % anatase titanium dioxide (TiO2) having an average particle size (aps) 100 nm; (iii) a non-aqueous solvent; and (iv) one or more alkyl silicate binders.

A hard coating film containing a polymer nanoparticle (A) and a matrix component (B), wherein a Martens hardness HM.sub.A of the polymer nanoparticle (A) and a Martens hardness HM.sub.B of the matrix component (B) satisfy a relationship of HM.sub.B/HM.sub.A>1, and a Martens hardness HM of the hard coating film is 100 N/mm.sup.2 or more.

The present invention provides a black light shielding component with low gloss and high blackness, capable of achieving a black color close to pure black. The black light shielding component comprises a substrate and a light shielding layer (3) formed on at least one surface of the substrate. The light shielding layer (3) contains black microparticles, chain-like structure materials (33), and a resin component (31). By using chain-like silica as the chain-like structure materials (33), an L value of 7 or less, a spectral reflectance of 0.8% or less for light at a wavelength of 360 nm, and a highly black, near-pure black color can be achieved.

Provided is a spectacle lens including a lens base material and an organic layer that contains a cationic organic compound.

The present invention relates to a decorative, or security element and a method for producing the decorative, or security element. The decorative, or security element comprises in this order (a) a substrate; (b) a coating, comprising transition metal particles (A) having a number mean diameter of from 15 nm to 700 nm, wherein the transition metal is selected from silver, copper, gold and palladium, especially silver and copper, very especially silver; (c) optionally a protective coating; wherein the coating (b) is derived from (b1) a solvent based composition, comprising the transition metal particles and a vehicle; and (b2) the coating (b) has a three layer structure: (b2a) a layer, comprising the transition metal particles and a vehicle; (b2b) a layer, comprising the vehicle, which is essentially free of transition metal particles; (b2c) a layer, comprising the transition metal particles and the vehicle. The method comprises the steps of i) applying a solvent based composition comprising transition metal particles and the vehicle; on at least part of the surface of the substrate, and ii) drying the solvent based composition; iii) curing the solvent based composition so as to form the three-layer structure which exhibits intensive angle-dependent colors in reflection on the coating side and/or on the substrate side of the decorative, or security element and a distinctive color in transmission; and iii) optionally applying a protective coating on the coating (b). The three-layer structure exhibits intensive angle-dependent colors in reflection on the coating side and, optionally, on the substrate side, due to thin-film interference in a Fabry-Perot resonator structure, which is produced in one coating or printing step.

A multilayer coating film includes a lustrous layer containing a luster material, and a colored layer stacked on the lustrous layer, containing a reddish coloring agent, and having translucency. For the lustrous layer, when a light incident angle (an angle with respect to a line perpendicular to the surface of the lustrous layer) is 45 and L*() represents the L* value of the lightness index of reflected light measured at a light receiving angle (the angle of inclination toward a light source side from a specular reflection direction) , L*() at 4580 and 100110 is 10 or less, and when the luster material is projected onto the bottom surface of the lustrous layer, the percentage of the projected area of the luster material on the bottom surface is 3% or more to 70% or less per unit area.

This disclosure relates to a glucose-sensing electrode including a nanoporous metal layer and a maltose-blocking layer formed over the nanoporous metal layer. The nanoporous metal layer is capable of oxidizing both glucose and maltose without an enzyme specific to glucose or maltose in the glucose-sensing electrode. The maltose-blocking layer has porosity that permits glucose to pass therethrough and inhibits maltose from passing therethrough toward the nanoporous metal layer.
