A method of producing an anti-reflection film includes forming a first layer on a transparent substrate, forming a second layer on the first layer, and forming the third layer on the second layer. When an optical admittance Y at a surface of the second layer is represented by, where i is the imaginary number unit,thicknesses and reflective indexes of the substrate, first layer, second layer, and third layer are selected so that x and y satisfy the following formula,0.9{()/2&#x2212;()/2&#x3c;1.1{()/2}where n is a refractive index of the third layer and nis a refractive index of an outer region at an outside of the anti-reflection film.

An antireflection film is formed of an organic film, and a hard-coating layer, a high refractive index layer and a low refractive index layer laminated in this order on the organic film. The high refractive index layer is formed of metal oxide particles of ITO with electrical conductivity and TiOwith high refractive index, and synthetic resin. A volume percentage of the TiOparticles to a total volume of the TiOand ITO particles in the high refractive index layer is 1 to 60%, and a volume percentage of the metal oxide particles to a total volume of the metal oxide particles and the synthetic resin is 20% or more.

Antireflection film

An antireflection film is formed of an organic film, a hard hard coating layer on the organic film, a first layer coated on the hard coating layer, and a second layer having an index of refraction lower than that of the first layer and coated on the first layer. The first layer is formed of a synthetic resin having pores therein and metallic oxide particles contained in the synthetic resin. The metallic oxide is at least on selected from the group consisting of ZrO, TiO, NbO, ITO, ATO, SbO, InO, SnOand ZnO. The synthetic resin is ultraviolet ray curable resin or electron beam curable resin. The second layer partly enters the pores of the first layer to firmly bond to the first layer through the pores.

Process for producing rubber-based composite material

A process for producing a rubber-based composite material including steps of laminating a rubber compound onto a substrate, with a bonding layer of metal or metal compound interposed therebetween, and subsequently vulcanizing the rubber compound, characterized in that a prime-coating film is interposed between the substrate and the bonding film of metal or metal compound. The rubber-based composite material retains good bond strength even when used in such a way that its bond interface is in contact with water. In addition, it has good adhesion to the substrate treated by conversion treatment.

Disclosed is a solar battery module including: a solar battery cell; and a surface material laminated to cover a surface of said cell; wherein a photocatalyst layer is formed on said surface material. With this module, it is possible to prevent contamination to the surface material of a solar battery module and prevent loss of sunlight irradiation energy to the solar battery, and hence to maintain an electric generation power for a long time.

A process for surface treatment of a vulcanized rubber is disclosed, said process comprising: generating a nonequilibrium low-temperature plasma under atmospheric pressure between a cathode and an insulating dielectric which is interposed between the cathode and an anode while introducing a gas for generating plasma to a plasma-generating region between the cathode and the insulating dielectric, placing the vulcanized rubber in air and outside the plasma-generating region so that a surface of the vulcanized rubber faces the plasma-generating region, and directing the gas from the plasma-generating region toward the surface of the vulcanized rubber so that the gas impinges against the rubber surface for effecting surface treatment.

A cleaning method for realizing uniform ashing of residues at a high efficiency by uniformly injecting neutral active species directly toward the surfaces of vulcanization residues left on a vulcanization mold is described. The method includes setting a ring-shaped cavity in face-to-face reaction with the inner surfaces of a ring-shaped vulcanization mold in a vacuum treating vessel, transmitting a microwave in the cavity, and emitting the microwave via a number of coupling slots formed in the outer side of the cavity toward the inner surfaces of the vulcanization mold whereupon a reaction gas is injected in the space of the treating vessel between the inner surfaces of the vulcanization mold and the cavity, so that a plasma including a major proportion of neutral active species generated from the reaction gas and the emitted microwave, and the elastomer residue is ashed by means of at least one gas selected from the plasma gas and a neutral active species-containing gas. A microwave generator useful for the method is also described.
