Abstract
The present invention is for providing a synthetic resin composition capable of effectively deodorizing amine malodor causing substances such as trimethyl amine. In a synthetic resin composition comprising an aqueous medium, a surfactant, and a polymer latex and a filler dispersed in the aqueous medium by the surfactant, a transitional metal supported silica gel having at least one selected from the group consisting of a transitional metal and a transitional metal compound supported by a silica gel and an activated carbon were used as the filler. Since the transitional metal or the transitional metal compound has an performs extremely well as a Lewis acid, it forms a complex with a Lewis base having an unpaired electron. That is, a malodor causing substance such as amines and ammonia having a nitrogen atom with an unpaired electron can be adsorbed efficiently.
