Abstract
Provided is a silicone impression material with high hydrophilicity that exhibits instantaneous hydrophilicity before being cured, that exhibits high hydrophilicity after being cured, that has preferable properties for a dental impression material, and that has good preservation stability. A sorbitan fatty acid ester based surfactant and a nonionic surfactant composed of polyester modified silicone are used in combination as a hydrophilizing agent not containing a siloxane polymer and a hydrophilizing agent containing a siloxane polymer, respectively.
