Herein disclosed are an α-(aminocydonexyl)alkylamine represented by the following general formula (II):
wherein R represents hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, provided that the amino group bonded to the cyclohexyl group may be in either of the 2-, 3- and 4-positions and a method for preparing it; an a-(isocyanatocyclohexyl)alkylisocyanate of Formula (II) wherein the amino groups are replaced with isocyanato groups and a method for preparing it; polyisocyanato-isocyanurate represented by the following general formula (IV):
wherein Ri, R2 and R3 may be the same or different and each represents a group represented by the following general formula:
wherein R represents hydrogen atom or an alkyl group having 1 to 5 carbon atoms and n is an integer ranging from 1 to 5 and a method for preparing it; and a resin obtained by polymerizing an organic polyisocyanate containing not lower than 10% by weight of the polyisocyanato-isocyanurate represented by Formula (IV) and a compound having at least two active hydrogen atoms as well as a resin composition for coating materials which comprises the resin.
本发明公开了由以下通式(II)代表的α-(氨基环己基)烷基胺:
其中 R 代表氢原子或具有 1 至 5 个碳原子的低级烷基,但与环己基键合的氨基可位于 2、3 和 4 位中的任一位置;式(II)的 a-(异氰基环己基)烷基异氰酸酯(其中氨基被异氰酸基取代)及其制备方法;由以下通式(IV)表示的聚异氰酸酯:
其中 Ri、R2 和 R3 可以相同或不同,且各自代表下式通式所代表的基团: 其中 R 代表氢原子或具有 1 至 5 个碳原子的烷基,n 为 1 至 5 的整数,以及制备方法;通过聚合有机多异氰酸酯获得的树脂,该有机多异氰酸酯含有不低于 10%(按重量计)的由式(IV)代表的多异氰酸酯和至少具有两个活泼氢原子的化合物,以及包含该树脂的用于涂层材料的树脂组合物。
