Patent ID: 8716375

Claim:
An organosilicon compound, characterized by having a cyclic structure with nitrogen atom and silicon atom, and one or more sulfur atoms in its molecule, and having a bonding site of at least one selected from the group consisting of a hydrogen atom, methyl group and hydroxyl group to silicon atom, which is represented by the following general formula (I): wherein A is a group containing at least one selected from the group consisting of polysulfide group, thioester group, thiol group, dithiocarbonate group, dithioacetal group, hemithioacetal group, vinylthio group, α-thiocarbonyl group, β-thiocarbonyl group, S—CO—CH 2 —O moiety, S—CO—CO moiety and S—CH 2 —Si moiety; W is represented by —NR 4 —, —O— or —CR 4 R 5 —, wherein R 5 is —R 6 or —C m H 2m —R′, provided that R 7 is —NR 4 R 6 , —NR 4 —NR 4 R 6 or —N═NR 4 , and R 4 is —C n H 2n+1 and R 6 is —C q H 2q+1 , and m, n and q are independently 0-20; R 1 and R 2 are independently -M-C 1 H 21 —, wherein M is —O— or —CH 2 — and 1 is 0-10, provided that M in one or more of R 1 and R 2 is —O—; and R 3 is a hydrogen atom, methyl group or hydroxyl group.
