A transparent soft PVC resin film or sheet containing a Zn stabilizer is likely to cause whitening by water absorption. However, according to the present invention, 20 parts by weight or more of a plasticizer is added to 100 parts by weight of PVC resin, and a Ba-Zn-based or Ca-Z-based resin is added.
Also for a transparent soft PVC resin film or sheet containing an n-based stabilizer, by using a resin composition added in combination with an epoxy resin and an acrylic processing aid, after being immersed in normal temperature water for 24 hours. It can be seen that the haze value does not increase much as compared with the haze value before immersion in normal temperature water, and transparency is maintained. Therefore, according to the present invention, it is possible to obtain a film or sheet that suppresses whitening by water absorption to the same extent as when mercaptotin is used as a stabilizer and is excellent in weather resistance.
