PROBLEM TO BE SOLVED: To enable surface roughness not to be caused even if a plaster model is immediately manufactured by using an alginate impression material-made tooth form manufactured by using a bonding material formed by containing polyamine compound including amino groups two or more in one molecule and an organic solvent.SOLUTION: A kit for bonding a dental alginate impression material to an impression tray is formed by including (A) an adhesive used between a dental alginate impression material containing (I) an polyamine compound having two or more amino groups in one molecule and (II) an organic solvent, and an impression tray and (B) a washing liquid, made from an aqueous acid solution which forms a water soluble salt when it is reacted with a calcium ion, suitably an ascorbic acid aqueous solution, for an alginate impression material-made tooth form obtained by carrying out impression extraction in a style in which the impression tray is bonded to the dental alginate impression material by using (A) the adhesive.COPYRIGHT: (C)2013,JPO&INPIT【課題】 1分子中にアミノ基を2個以上含むポリアミン化合物、有機溶剤を含有してなる接着材を用いて作製したアルジネート印象材製歯型について、これを用いて続けて石膏模型を作製しても、表面荒れが生じないようにすること。【解決手段】 (A)I)1分子中にアミノ基を2個以上含むポリアミン化合物、II)有機溶剤を含有してなる歯科用アルジネート印象材と印象用トレーとの接着剤、及び(B)カルシウムイオンと反応した際に水溶性塩を形成する酸の水溶液、好適にはアスコルビン酸水溶液からなる、上記(A)接着剤を使用して印象用トレーを歯科用アルジネート印象材に接着する態様で印象採取して得たアルジネート印象材製歯型の洗浄液、を含んでなる歯科用アルジネート印象材と印象用トレーとの接着キット。【選択図】 なし
