<P>PROBLEM TO BE SOLVED: To develop a preservation solution capable of highly reducing the dimensional change of a cured product of an alginate impression material by syneresis and drying, and enabling the long-term preservation thereof. <P>SOLUTION: The preservation solution for the alginate impression material comprises an aqueous solution of saccharides, especially a nonreducing sugar exemplified by trehalose. The saccharides of 1-80 pts.mass are preferably dissolved in 100 pts.mass of water, and when the cured body of the alginate impression material of the preservation object contains the nonreducing sugar, the effects of reducing the dimensional change are exhibited especially remarkably to make preferable embodiment. <P>COPYRIGHT: (C)2013,JPO&INPIT |
