| 摘要 |
The present invention discloses a resin having a nitrogen-carbon-sulfur bond. The nitrogen-carbon-sulfur bond is constituted by a nitrogen atom, a carbon atom, and a sulfur atom, bonding in the stated order, and the bond between the carbon atom and sulfur atom and/or the bond between the carbon atom and nitrogen atom is a single bond. When the number average molecular weight of this resin is defined as Mn and the number of sulfur atoms constituting the nitrogen-carbon-sulfur bonds contained per resin molecule is defined as n1, Mn is 500 or higher and Mn/n1 is from 50 to 300 inclusive. |
