    • There is provided an urethane modified epoxy resin either obtained by reaction of 100 weight portions of a preliminary condensate �A! produced by reaction of an epoxy resin and an acid of a phosphorus compound or its salt or ester and 5 to 60 weight portions of an isocyanate group-terminated urethane prepolymer �B! produced by reaction of a hydroxy compound and an organic polyisocyanate compound, or obtained by preparing an urethane modified epoxy resin �D! from 100 weight portions of an epoxy resin and 5 to 60 weight portions of the same isocyanate group-terminated urethane prepolymer �B! as the above and causing the resin �D! to react with an acid of the same phosphorus compound as the above or its salt or ester. Such an urethane modified epoxy resin can advantageously be used with an active organic hardening agent to produce an adhesive resin composition, which is highly effective for bonding iron and non-ferrous metals particularly in terms of shearing strength and peeling strength.
    • 提供了一种聚氨酯改性环氧树脂,其通过将100重量份由环氧树脂与磷化合物或其盐或酯的酸反应制备的预缩合物[A]和5-60重量份的 通过羟基化合物和有机多异氰酸酯化合物的反应制备的异氰酸酯基封端的氨基甲酸酯预聚物[B],或者是由100重量份的环氧树脂和5〜60重量份的聚氨酯改性环氧树脂 与上述相同的异氰酸酯基封端的氨基甲酸酯预聚物[B],并使树脂[D]与与上述相同的磷化合物的酸或其盐或酯反应。 这种氨基甲酸酯改性环氧树脂可以有利地与活性有机硬化剂一起使用以产生粘合剂树脂组合物,其对于铁和有色金属的粘合特别是在剪切强度和剥离强度方面是非常有效的。
