To provide a sealant material composition securing a good sealability while suppressing a flow of a sealant in travel, simultaneously realizing these properties in a good balance.SOLUTION: A sealant material composition composes a sealant layer 10 arranged on an inner surface of a pneumatic tire. The sealant material composition to be used has a ratio A of toluene insoluble being 30 to 60 mass% in the sealant material composition expressed by a formula (1): A=(W2/W1)×100 (1), (In the formula, W2 is a mass [unit: g] of the toluene insoluble remaining after the sealant material composition is immersed in toluene and kept standing for one week, and W1 is an initial mass [unit: g] before the sealant material composition is immersed in the toluene.SELECTED DRAWING: Figure 1

    【課題】走行中のシーラントの流動を抑制しながら、良好なシール性を確保し、これら性能をバランスよく両立することを可能にしたシーラント材組成物の提供。【解決手段】空気入りタイヤの内表面に配置されたシーラント層10を構成するシーラント材組成物として、下記(1)式で表されるシーラント材組成物中に占めるトルエン不溶分の割合Aが30質量%~60質量%であるものを用いる。A=(W2/W1)×100(1)(式中、W2は前記シーラント材組成物をトルエンに浸漬させて1週間放置した後に残存したトルエン不溶分の質量〔単位:g〕であり、W1は前記シーラント材組成物をトルエンに浸漬する前の初期質量〔単位:g〕である。)【選択図】図1
