摘要： A polyurethane resin which is the reaction product of at least one diisocyanate and a group of components having isocyanate reactive functional groups. The group of components includes a first group of one or more polyether polyols each having an average molecular weight in the range of 1000 to 10000 g/mol, a second group of one or more polyether polyols each having an average molecular weight in the range of 400 to 10000 g/mol and being hydrophilic and water-soluble, a third group of one or more polyols each having an average molecular weight equal to or less than 800 g/mol, at least one amine, and a reaction terminating agent. The ratio of the equivalent weights of the diisocyanate to the components having isocyanate reactive functional groups is selected such that essentially all of the isocyanate groups of the diisocyanate are present only as the reaction product with one of said isocyanate reactive functional groups.
