Zusammenfassung: | To provide a paste vinyl chloride resin particle which has high surface strength and foamability, and has excellent characteristics, in particular, for foamed wall paper.SOLUTION: Paste vinyl chloride resin particle is provided which includes a primary particle of vinyl chloride resin, and satisfies the following characteristics (1) to (3). (1) The vinyl chloride resin particle has such particle size distribution that primary particles with a particle size of 0.05-10 μm are continuously distributed, a particle component of less than 0.5 μm is 20-70 vol.%, and a particle component of 0.5 μm or more and less than 5.0 μm is 80-30 vol.%. (2) A degree of polymerization of the vinyl chloride resin is 1,200 or more and 2,200 or less. (3) The vinyl chloride resin particle includes 0.05 pts.wt. or more and 2.5 pts.wt. of less of alkyl benzene sulfonate with respect to 100 pts.wt. of the vinyl chloride resin.SELECTED DRAWING: None
