<P>PROBLEM TO BE SOLVED: To provide a sound absorption undercoat composition in which sound such as oscillating sound is absorbed, and is made hard to become a noise source to a surrounding area. <P>SOLUTION: The sound absorption undercoat composition is obtained by thermally curing a plastisol composition which includes at least a thermoplastic resin powder, a plasticizer, a foaming agent, and a filler, wherein as the thermoplastic resin powder, a vinyl acetate/polyvinyl chloride copolymer resin in a range of a polymerization degree of 1,000-1,500 is made a principal component, or a vinyl acetate/polyvinyl chloride copolymer resin having a different polymerization degree from the principal component is used together with the principal component. <P>COPYRIGHT: (C)2012,JPO&INPIT |
