樹脂フィルムは得られていない。2. Description of the Related Art A film made of an olefin resin is inferior in weather resistance, and as a means for coping with this, an ultraviolet absorber and a hindered amine compound are added. However, when the ultraviolet absorber and the hindered amine compound are added in an amount sufficient to obtain the desired weather resistance, there is a problem that bloom (a phenomenon in which the ultraviolet absorber and the hindered amine compound migrate to the film surface) occurs. . Therefore, the addition amount of the ultraviolet absorber and the hindered amine compound has to be suppressed to such an extent that bloom does not become a problem, and an olefin resin film having sufficient weather resistance has not been obtained.

Therefore, it is desirable to blend polyethylene, especially low density polyethylene, in order to improve embossability. If the proportion of the polyethylene blend is too small, the blending effect will not be exhibited, and if it is too large, the amount of isotactic polypropylene will be relatively too small to obtain a suitable hardness for the cosmetic film, 10 to 300 parts by weight, preferably 30 to 200 parts by weight, of polyethylene (preferably low density polyethylene) is suitable for 100 parts by weight of isotactic polypropylene.

ている。The colored film and the transparent film of the present invention can be produced by means such as a T-die extrusion method, a calendering method and an inflation method, and the production method is not particularly limited. In order to improve the calenderability, it is preferable to blend syndiotactic polypropylene with the above isotactic polypropylene. If the ratio of the syndiotactic polypropylene blend is too small, the blending effect is not exhibited, and if it is too large, the amount of isotactic polypropylene becomes relatively too small, so that a hardness suitable for a cosmetic film can be obtained. Therefore, 5-200 parts by weight of syndiotactic polypropylene is suitable for 100 parts by weight of isotactic polypropylene.

It is desirable to mix rubber components such as R and polybutene. The compounding ratio of the rubber component varies depending on the desired impact strength, and cannot be unconditionally determined. However, in the colored film and the laminated transparent film of the present invention, 10 to 200 parts by weight with respect to 100 parts by weight of the olefin resin.

As the olefin resin for dilution at this time, a resin having excellent compatibility with the olefin resin used for the colored film (particularly preferably the same kind of resin) is used. When using a blend, it is possible to easily and reliably obtain a uniform mixing state by using an olefin resin having a melting point equal to or lower than the melting point of the olefin resin having the highest melting point in each olefin resin to be blended. Desirable above. The degree of dilution is not particularly limited, and those having a pigment concentration of about 1 to 70 wt% in the diluted pigment can be used.
