A pasty dental alginate impression material composition having features that fluidity of a mixture is changeable by changing mixing ratio of both pastes, sufficient working time can be kept, and liquid separation in abase material paste does not occur during storage, comprises the base material paste composed mainly of 1-20 wt. % alginate and water, and a setting material paste composed mainly of 10-60 wt. % calcium sulfate and a liquid component unreactive with the calcium sulfate, wherein the base material paste does not contain a filler substantially, but contains 0.01-5 wt. % carbonate of sodium or potassium as a retarder and 0.01-15 wt. % one or more polysaccharides such as carrageenan, pullulan, curdlan, xanthan gum, pectin, konjak glucomannan, and locust bean gum, and the setting material paste contain 0.01-10 wt. % phosphate of sodium or potassium as a retarder, and 0.5-30 wt. % polybutene.
A pasty dental alginate impression material composition, comprising a base material paste composed mainly of 1-20% by weight of alginate and water, and a setting material paste composed mainly of 10-60% by weight of calcium sulfate and a liquid component which is not reacted with the calcium sulfate, wherein said base material paste does not contain a filler substantially, but contains 0.01-5% by weight of carbonate of sodium or potassium as a retarder, and 0.01-15% by weight of one or more polysaccharides selected from carrageenan, pullulan, curdlan, xanthan gum, gellan gum, pectin, konjak glucomannan, xyloglucan, guar gum, gum Arabic and locust bean gum, and
