A screen plate for screen printing is provided with a plate frame, a supporting body screen having an outer peripheral part fixed to the plate frame, and a printing screen having an outer peripheral part fixed to the supporting body screen. The supporting body screen is made of an n/m twilled weave textile, wherein n and m independently represent an integer of 2 or more. The screen plate has excellent printing accuracy.

Screen plate

To provide a mesh member such that a static charge can be suppressed. Provided is a mesh member including a mesh woven fabric and a coating layer that is formed on the surface of the mesh woven fabric and contains a carbon nanotube and/or graphene.

Mesh member, sieve, and screen printing plate

To provide a screen plate that can allow printing accuracy to be improved. A screen plate comprising a plate frame and a screen gauze formed of warp and weft fibers each made of a synthetic fiber, wherein the screen gauze is stretched on the plate frame under application of a predetermined tensile force, and the thickness of the screen gauze stretched on the plate frame is 88% or less based on the thickness of the screen gauze under application of no tensile force.

Screen plate and method for manufacturing same

To provide an antiviral resin member which can efficiently inactivate viruses and has excellent sustainability. An antiviral resin member comprising a resin, an antiviral agent, and a surface potential-controlling agent, characterized in that the surface potential-controlling agent causes the surface potential of the antiviral resin member to shift to a value on the positive side of the potential of the resin alone.

Antiviral resin member

An inorganic fine particle layer containing inorganic fine particles and a binder component is formed on a surface of a substrate by chemical bonding. The inorganic fine particles are coated with silane monomer each having an unsaturated bond. The content of the binder component is in the range of 0.1% by mass to 40% by mass to the content of the inorganic fine particles.

Antifouling composite material

A method of making a photocatalytic material comprising a base substance and photocatalytic particles bonded on the base substance by chemical bonding through a silane compound. The chemical bonding is bonding a reactive group of the silane compound through graft polymerization to a radical produced on a resin surface of the base substance by irradiating radiation ray. The resulting photocatalytic material has the advantage that, even when used over a long time, the photocatalytic particles are less apt to shed and the resin base is less apt to deteriorate.

Method of making a photocatalytic material

A photocatalytic material which comprises a resin base and photocatalyst particles tenaciously deposited thereon in such a manner that the function of the photocatalyst is not impaired. Even when the photocatalytic material is used over long, the photocatalyst particles are less apt to shed and the resin base is less apt to deteriorate. In the photocatalytic material, the photocatalyst particles have been bonded to the base by chemical bonding through a silane compound. The photocatalytic material is characterized in that the chemical bonding through a silane compound is bonding by graft polymerization, and that the graft polymerization is radiation-induced graft polymerization.
