進行し易い欠点があった。Synthetic leather is known that has a top-coated transparent resin layer provided on the printed layer to prevent wear and damage of the printed layer, but this type of synthetic leather is a leather without a top-coated transparent resin layer. This deterioration phenomenon occurs mainly on the surface of the upper transparent resin layer, but it is not limited to this area because light passes through the transparent resin layer!
f It also affects the layers below the transparent layer (print layer, hollow resin layer, etc.). In addition, the transparent layer has the disadvantage that a portion of the light that has passed through the transparent layer is reflected by the lower layer and returned to the transparent layer, resulting in further deterioration.

中側樹脂層より上引透明性樹脂層に多量に混入させる。The present invention is constructed by mixing an ultraviolet absorber into the upper transparent resin layer 5 and the middle resin layer 3. As the ultraviolet absorber, used are benzotriazole-based, benzophenone-based, salicylate ester-based, benzoate ester-based ultraviolet absorbers, and compounds obtained by combining these ultraviolet absorbers with antioxidants. The amount of the ultraviolet absorber mixed is O.1 to 100 parts by weight of the resin for forming each resin layer.
About 1.0 ffiffi part is preferable, and in order to impart superior weather resistance to the synthetic leather, a larger amount of the ultraviolet absorber is mixed into the upper transparent resin layer than the middle resin layer.
この際の混入比率は、上引透明性層混入ｆｆｉ：中引Ｍ

ましい。In the synthetic leather of the present invention, light stabilizers, antioxidants, anti-urethane agents, flame retardants, etc. may be added to predetermined layers as necessary. Among these additives, in particular, hindered amine light stabilizers, etc. It is preferable to add a light stabilizer in combination, and in this case, the weather resistance performance can be further improved. 0. About 1 to 0.5 parts by weight is recommended (similar to the UV absorber, it is better to mix it in a larger amount in the top transparent resin layer than in the middle resin layer, and the mixing ratio at that time also depends on the amount of the UV absorber). The same range as the mixing ratio is preferable.

止される顕著な効果がある。Measurement [Effect of the Invention] As explained above, the weather-resistant synthetic leather of the present invention has a transparent top resin layer and a cow resin layer mixed with an ultraviolet absorber. Even if the transparent layer contains a large amount of ultraviolet absorber, it is difficult for weather resistance to deteriorate.Especially when a large amount of ultraviolet absorber is mixed in the upper transparent layer of the above two layers, external light is sufficiently blocked by the transparent layer. This has the remarkable effect of preventing deterioration of each layer and also preventing deterioration of the transparent layer due to reflected light from the lower layer.
更に光安定剤を添加した場合には、より劣化防止効果が
向上するものである。Furthermore, when a light stabilizer is added, the deterioration prevention effect is further improved.
