PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin product having suppressed yellow discoloration over time or the like even when arranged under severe environment in outdoor for a long time, at low cost and excellent in light resistance.SOLUTION: There is provided a polyvinyl chloride resin product containing titanium oxide particle as a white pigment and further a filler, the titanium oxide particle is surface treated by an organic material at the amount of over 0 mass% and 5.0 mass% or less based on the added amount of the titanium oxide particle, the filler has average particle diameter in a range of 0.1 to 5.0 μm, distribution density on a product surface at an initial status of the polyvinyl chloride resin product of 30 (/5 μm) or more, average closed diameter of fine pores formed by deriving from the filler after irradiating a laboratory light source to the surface of the polyvinyl chloride resin product for 3000 hours of 0.1 to 5.0 μm and distribution density of the fine particles on the surface of 30 (/5 μm) or more.SELECTED DRAWING: Figure 1 |
