摘要： PURPOSE: To obtain an alginate impression material composition excellent in processability and preservation stability. CONSTITUTION: This impression material composition is obtained by compounding a component capable of causing a disadvantageous change under service conditions in the presence of water, e.g. an alkali metallic alginate, calcium sulfate dihydrate, an alkali metallic phosphate, a fluoride or a metallic oxide, etc., in an anhydrous paste A and compounding a component without causing the disadvantageous change under service conditions in the presence of water, e.g. an inert filler in a water-based paste B in the alginate-based impression material composition comprising two kinds of paste components. The impression material composition has excellent processability and stable in preservation. The paste A contains glycerol, a glycol, polyethylene glycol and/or polypropylene glycol as a paste-forming agent and the paste B contains a get-forming agent such as carboxymethyl, methyl, hydroxyethyl or hydroxypropyl cellulose, an alkali metallic polyacrylate or a copolymer.
