2. Description of the Related Art Synthetic resin moldings such as polymethylmethacrylate resin, polycarbonate resin and polyarylate resin are not only lighter in weight and superior in impact resistance than glass, but also inexpensive. It has various advantages such as easy molding and is widely used in many fields by taking advantage of these advantages. For example, it is used for glazing of automobiles, buses, aircrafts, etc., headlamp lenses, corner lenses, lenses such as fog lamps, lenses for spectacles and optical devices, automobile meter panels, etc. .

However, since the surface hardness of these synthetic resin molded products is insufficient, contact with other objects, impact, and the like during transportation of the molded product, attachment of parts, or use.
There is a strong demand for improving the wear resistance of the surface because the surface is likely to be damaged by scratches and the like, the product yield is lowered, the aesthetic appearance is impaired, and the product becomes unusable in a short time. In addition, since these synthetic resin molded products have high electrical insulation, static electricity is generated by friction, contact, etc., and they become charged, so that dust easily adheres to the surface of the molded product, which causes scratches and is aesthetically pleasing. Not only is it damaged, but it also has an adverse effect such as malfunction on electronic circuits and the like in the vicinity thereof.

Various methods have been hitherto used for improving the drawbacks of such synthetic resin molded articles. For example, a polyfunctional monomer having two or more (meth) acryloyloxy groups in one molecule. An ionic compound, such as an anionic, cationic or amphoteric surfactant, is added to a coating composition containing as a main component, the coating is applied to the surface of a synthetic resin molded article, and ultraviolet rays are applied to form a cured film. A method of improving wear resistance and antistatic property of a synthetic resin molded product by forming the same has been proposed.

[0005]

However, the coating composition of the above method has the following problems. First, there is a problem that abrasion resistance and antistatic property are not compatible with each other. When the added amount of the surfactant is small, the wear resistance is excellent, but the performance of antistatic property is insufficient. Conversely, when the added amount of the surfactant is large, the antistatic property is excellent, but the wear resistance is poor. Will be enough. Also, as the amount of surfactant added increases,
It is difficult to form a practical cured film because the transparency and the adhesiveness also decrease.

The second problem is durability. It is desirable that the antistatic effect lasts semi-permanently. Especially, the antistatic effect is deactivated in repeated washing with water, and in a harsh environment (temperature and humidity), and the transparency and adhesion are improved. It is not preferable to decrease. The coating composition of the above disclosure has insufficient durability, and deterioration in antistatic property, transparency, and adhesion are observed, and therefore the durability has not reached a practical level.

The present invention has been made on the basis of the above-mentioned background, and an object of the present invention is to provide abrasion resistance, chemical resistance, durability, weather resistance, and adhesion to a substrate on the surface of the substrate. An object of the present invention is to provide an antistatic coating material composition having excellent properties and capable of forming an excellent crosslinked cured film having permanent antistatic property.

[0008]

As a result, colloidal silica, specific organoalkoxysilane, polymerizable (meth) acrylate , A coating composition containing an antistatic agent and an active energy ray-sensitive catalyst mixed in a specific ratio is applied to a synthetic resin molded article and cured by irradiation with active energy rays, whereby transparency, abrasion resistance, and The present invention has been completed by finding that a synthetic resin molded product excellent in antistatic property and durability can be obtained.

That is, according to the present invention, (A) the primary particle size is 1
5 to 50 parts by weight of colloidal silica composed of silica particles of ˜200 mm, (B) General formula (R ¹ ) _a —Si— (OR ² ).
_4-a [I] (in the formula, R ¹ and R ² represent a monovalent hydrocarbon group having 1 to 6 carbon atoms and may be the same or different; a represents an integer of 1 to 3). Organoalkoxysilanes 1-40 shown

(Wherein the total amount of A, B, C, D and E is 100 parts by weight), which is an antistatic coating material composition.

The above antistatic coating material composition is applied to the surface of a synthetic resin molded article and irradiated with active energy rays to obtain a wear-resistant and chemical-resistant coating having a crosslinked cured coating with a thickness of 1 to 30 μm. It is possible to obtain a synthetic resin molded product having excellent properties, durability, weather resistance, and antistatic property. The present invention will be described in detail. First, each component of the antistatic coating material composition of the present invention will be described.

Component (A) The component (A), colloidal silica composed of silica particles having a primary particle size of 1 to 200 millimicrons, is generally an ultrafine colloidal solution of silicic acid anhydride using a dispersion medium. is there. Further, powdery colloidal silica containing no dispersion medium can also be used in the present invention.
