Embodiment 1
[0156] Use complexes containing:
[0157] 100 parts by mass of the above (1-1);
[0158] 35 parts by mass of the above-mentioned (2-1);
[0159] 10 parts by mass of the above (2-2);
[0160] 0.8 parts by mass of the above (3-1);
[0161] 2.0 parts by mass of the above (4-1);
[0162] Using an apparatus equipped with a uniaxial extruder and a T-die, a film having a thickness of 10 μm was produced under conditions of a maximum shear rate of 200 (1 / s) applied during film formation.
[0163] GPC measurement of the thus obtained film was performed to generate component (A). The polystyrene-equivalent molecular weight of the peak top of the component (A) in the GPC curve was 10^6.5. The value of the content of the component (A) calculated from the GPC curve by the formula described in the above paragraph 0028 was 2.8% by mass. In addition, there was no component having a peak top in a region where the polystyrene-equivalent molecular weight exceeded 10^7.0.

Embodiment 7～12
[0168] Film production was performed in the same manner as in Example 1 except that the composition of the vinyl chloride-based resin composition used was changed as shown in Table 1. None of the components had a peak top in a region where the polystyrene-equivalent molecular weight exceeded 10^7.0. The results are shown in Table 1.

[0173] Symbol Description
[0174] 1: Peak of component (A)
[0175] 2: The area regarded as the content of component (A)
[0176] 3: Peak of component (B)
[0177] 4: The area regarded as the content of component (B)
[0178] 5: The position where the slope of the GPC curve is stably 0 near the polystyrene-equivalent molecular weight of 10^3.5
[0179] 6: The position where the differential molecular weight distribution curve (GPC curve) is the minimum value
[0180] 7: The position where the molecular weight in terms of polystyrene is 10^7.0 or more, and the inclination of the GP...
