摘要：
Provided is an organic sulfur material comprising a sulfur-modified acrylic resin, wherein an acrylic resin is at least one polymer selected from the group consisting of (a) a polymer of at least one selected from the group consisting of acrylate compounds represented by CH 2 = C(R 11 )COOR 12 (wherein, R 11 is a hydrogen atom or a methyl group, and R 12 is an alkyl group.) and (b) a polymer of at least one selected from the group consisting of acrylate compounds above and at least one selected from the group consisting of diacrylate compounds represented by CH 2 = C(R 21 )COO-Y-OCO(R 22 ) C = CH 2 (wherein, each of R 21 and R 22 is the same or different and is a methyl group, etc., Y is a hydrocarbylene group, etc., wherein the hydrocarbylene group may have a substituent selected from a hydroxyl group and an alkyl group.).
