Abstract
Abstract The invention proposes a foamable vinyl chloride-based resin composition capable of giving a shaped article having a cellular foamed structure and a beautiful surface with metallic luster. The composition comprises (a) 100 parts by weight of a vinyl chloride-based resin compound of a transparency formulation having a specified transparency, (b) 0.1-5 parts by weight of a powder of a metal or alloy having a specified average particle diameter, (c) 0.01-2 parts by weight of an organic dye or pigment and (d) 0.1-5 parts by weight of a blowing agent.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
91 words
A foamable vinyl chloride-based resin composition capable of giving a cellular foamed article having metallic luster on the surface which comprises: (a) 100 parts by weight of a vinyl chloride-based compound of a transparency formulation; (b) from 0.1 to 5 parts by weight of a powder of a metal or alloy having an average particle diameter in the range from 10 to 40 μm; (c) from 0.01 to 2 parts by weight of an organic dye or pigment; and (d) from 0.1 to 5 parts by weight of a blowing agent.
Claim 2
Dependent Claim
91 words
A foamable vinyl chloride-based resin composition capable of giving a cellular foamed article having metallic luster on the surface which comprises: (a) 100 parts by weight of a vinyl chloride-based compound of a transparency formulation; (b) from 0.1 to 5 parts by weight of a powder of a metal or alloy having an average particle diameter in the range from 10 to 40 μm; (c) from 0.01 to 2 parts by weight of an organic dye or pigment; and (d) from 0.1 to 5 parts by weight of a blowing agent.
Claim 3
Dependent Claim
59 words
The foamable vinyl chloride-based resin composition as claimed in claim 1 wherein the vinyl chloride-based resin compound of a transparency formulation has such a transparency that the light transmission of a plate having a thickness of 1 mm molded therewith is at least 70% as determined according to the testing method specified in JIS (Japanese Industrial Standard) K 6717.
Claim 4
Dependent Claim
48 words
The foamable vinyl chloride-based resin composition as claimed in claim 1 wherein the amount of the powder of a metal or alloy is in the range from 0.3 to 3 parts by weight per 100 parts by weight of the vinyl chloride-based resin compound of a transparency formulation.
