摘要:
Disclosed is a vehicle member that includes a molded body and a protective film disposed on a surface of the molded body and formed by curing of an active energy ray-curing composition. The active energy ray-curing composition contains an active energy ray-curing prepolymer (A) obtainable by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group, an active energy ray-curing compound (B) having a benzotriazole group, another active energy ray-curing compound (C) differing from the (A) component and the (B) component, and inorganic oxide particles (D). The acrylic-based prepolymer having the hydroxyl group is a copolymer that includes an acrylic monomer (a1) having a piperidinyl group, an acrylic monomer (a2) having a hydroxyl group, etc., as monomer units.

A resin board that consists of at least one of a mixture of a plurality of types of resins having different degrees of susceptibility to erosion by an ozone solution, and a resin having, in a molecule, a plurality of types of components having different degrees of susceptibility to erosion by the ozone solution is treated with ozone water to form a reformed layer, and a catalyst metal is adsorbed by the reformed layer so as to form a resin-metal composite layer, on which a plating process is performed. In the resin board, a component or components that is/are likely to be eroded on by the ozone solution dissolves into the ozone solution, and pores or clearances on the order of nanometers are formed between the component(s) and a component or components that is/are less likely to be eroded by the ozone solution. With the plating deposited in the pores or clearances, the adhesion strength is improved due to an anchoring effect. Thus, the adhesion strength of the plating film is improved even where the resin-metal composite layer has a thickness of 10 to 200 nm.

The process for producing an amorphous carbon film of the present invention is a process for producing an amorphous carbon film comprising contacting a surface of a substrate S with bubbles B which have been formed in a liquid L containing an organic compound and inside which plasma has been generated, so as to form an amorphous carbon film on the surface of the substrate S, and the liquid L contains one or more selected from phenols and alcohols having a carbon number of from 1 to 12. According to the present invention, a hard amorphous carbon film can be formed easily.

A slide member of the present invention is characterized in that it has: a substrate, which is made of a metal; an intermediate layer, which is formed on at least one of the surfaces of the substrate, and which is composed a first resinous composition including a thermoplastic polyimide resin and a polyaryl ketone resin; and a superficial layer, which is formed on the intermediate layer, and which is composed of a second resinous composition including a polyaryl ketone resin.Since the slide member of the present invention is such that it is possible to form it at low temperature, the deterioration of the substrate is suppressed; moreover, it is a slide member having a superficial layer, which includes a polyaryl ketone resin which is good in terms of the adhesiveness to a substrate.

A swash plate is operably connected through a lug plate and a hinge mechanism to a drive shaft, and slidably retained on an end part of each piston through a pair of front and rear shoes. A rotational motion of the swash plate following rotation of the drive shaft is converted through the shoes into a reciprocating motion of each piston. A thermoplastic polyimide coating is formed on the swash plate and the shoes as sliding components of a compressor. The thermoplastic polyimide coating may contain a solid lubricant. For the solid lubricant, for example, polytetrafluoroethylene is used. Thus, it is possible to obtain a compressor, which includes the sliding components having improved sliding characteristics, and is manufactured relatively easily.

A paint composition includes a raw polymer, and a dry solvent for dissolving the raw polymer. The raw polymer is composed of a transparent polymer having a hydroxyl group, and polysilazane. The polysilazane is included in an amount of 10% by weight or more with respect to the entire raw polymer taken as 100% by weight. Also disclosed are a process for producing a transparent protective film using the paint composition, and organic glass using the same. Note that the organic glass exhibits a surface hardness of 0.4 GPa or more.

A compressor includes a swash plate, and a shoe connected to an outer periphery of the swash plate. A surface of the swash plate slides upon a flat surface of the shoe. A sliding film is applied to the surface of the swash plate. The sliding film is formed of binder resin which contains a solid lubricant and titanium oxide powder. This allows the surface of the swash plate and the flat surface of the shoe to smoothly slide upon each other.
