Abstract

The disclosure generally describes carrier resins, and in particular, resins used for carrier coatings which include at least one ester functional group and at least one cyclic aliphatic group containing at least one nitrogen atom in the cyclic ring structure. Carriers having such resins in the coating exhibit high charge and excellent relative humidity (RH) sensitivity of charge to changing environmental conditions.
