When the light stabilizer is compounded, the compounding amount is preferably 10 parts or less, particularly preferably 5 parts or less based on 100 parts of the polyfunctional compound (A).

Further, in the present invention, an organic solvent may be added to the curable composition for the purpose of improving the coating properties of the curable composition and the adhesion to the aromatic polyester resin molded article. The organic solvent is not particularly limited as long as there is no problem in the solubility of the polyfunctional compound (A), the ultraviolet absorber (B), and other additives, and may be any as long as it satisfies the above performance. Two or more organic solvents can be used in combination. The amount of the organic solvent to be used is preferably 100 times by mass or less, more preferably 50 times by mass or less, with respect to the polyfunctional compound (A).

The method for applying the curable composition is not particularly limited, and a known method can be employed. For example, dip coating, flow coating, spray coating,
Shower coating method, ring coating method, spin coating method,
Various methods such as a bar coating method, a gravure coating method, a roll coating method, a blade coating method, an air knife method, a die coating method, and a microgravure coating method can be employed.

When coating on a film,
From the viewpoints of productivity, surface appearance, and continuous coating,
Preferred are a flow coating method, a spray coating method, a shower coating method, a gravure coating method, a roll coating method, a blade coating method, an air knife method, a die coating method and a microgravure coating method.

The light for curing the curable composition is not particularly limited, and ultraviolet rays, electron beams and the like can be used, but ultraviolet rays are preferred. As the ultraviolet light source, a xenon lamp, a pulse xenon lamp, a low-pressure mercury lamp, a high-pressure mercury lamp, an ultra-high-pressure mercury lamp, a metal halide lamp, a carbon arc lamp, a tungsten lamp and the like are preferable. Among these, a high-pressure mercury lamp or a metal halide lamp is preferable because the apparatus is simple and the productivity is excellent.

On the surface of the hard coat layer, a physical vapor deposition method such as sputtering or ion plating, a chemical vapor deposition method such as plasma CVD, or a wet coat is used.
An antireflection layer, a water-repellent layer, a hydrophilic layer, and the like can be formed.
