    • An adhesive composition comprises 100 parts by weight of a polymerizable monomer comprising (a) 1.5 to 100 parts by weight of a compound represented by general formula I or II: ##STR1## where R.sub.1 and R.sub.1 ' each stand for hydrogen or a methyl group, R.sub.2 stands for a divalent organic residue having 4 to 40 carbon atoms, X.sub.1 and X.sub.2 each stand for --O--, --S-- or --NH--, a is 0 or 1, and R.sub.3 stands for a group of the formula ##STR2## having 6 to 40 carbon atoms, where R.sub.4 and R.sub.4 ' each stand for a hydrocarbon group having 1 to 29 carbon atoms, and optionally replaced by a halogen atom, or a hydroxyl, amino or carboxyl group, b is an integer of 0 to 3, and Z stands for --O--, --COO-- or --NH--, a plurality of R.sub.4 ' (when b is 2 or 3) being the same or different, at least one of R.sub.4 and R.sub.4 ' having at least three carbon atoms, and (b) 0 to 98.5 parts by weight of a vinyl monomer copolymerizable with the above compound; and 0.01 to 20 parts by weight of a curing agent. It shows a superior adhesive strength on any of hard tissues in a living body, such as teeth and bones, metals, organic polymers and ceramics. It maintains a high adhesive strength for a long time even if it is exposed to moisture, or immersed in water. It is particularly effective for use in dentistry, though it is useful for a variety of other purposes, too.
    • 粘合剂组合物包含100重量份的可聚合单体,其包含(a)1.5至100重量份的由通式I或II表示的化合物:其中R 1和R 1 '各自代表氢或甲基,R2代表具有4-40个碳原子的二价有机残基,X1和X2分别表示-O - , - S-或-NH-,a是0或1,R3 代表具有6〜40个碳原子的式“IMAGE”的基团,其中R 4和R 4'各自代表具有1至29个碳原子的烃基,并且任选被卤素原子或羟基,氨基或羧基取代 基团,b为0〜3的整数,Z表示-O - , - COO-或-NH-,多个R 4'(当b为2或3)相同或不同时, R4和R4'具有至少三个碳原子,和(b)0至98.5重量份可与上述化合物共聚的乙烯基单体; 和0.01〜20重量份的固化剂。 它对生物体中的任何硬组织如牙齿和骨骼,金属,有机聚合物和陶瓷显示出优异的粘合强度。 即使暴露于潮湿或浸入水中,也能长时间保持高粘合强度。 它在牙科使用中特别有效,尽管它也适用于各种其他目的。
