| titleOfInvention | Aqueous polyurethane resin composition and aqueous metal surface-treatment composition containing same |
| abstract | An aqueous metal surface-treatment composition having an excellent corrosion-prevention effect and a superior paint-adhesion, includes a polyurethane resin prepared by reacting (I) an urethane prepolymer prepared by a reaction of a polyol compound having an average molecular weight of 300 or more, with a dimethylol alkanoic acid, a compound having 3 or more active hydrogen atoms and an organic polyisocyanate compound, and having terminal isocyanate groups, with (II) a polyamine compound having 2 or more primary amino groups, in a such a proportion that the molar amount of the primary amino groups of the polyamine compound (II) exceeds the molar amount of the isocyanate groups of the urethane prepolymer (I), the polyurethane resin having terminal primary amino groups, and an aqueous medium for dispersing the polyurethane resins therein, wherein the polyol compound for the preparation of the urethane prepolymer (I) comprises (1) a polyester-polyol prepared from an aliphatic polyhydric alcohol and a polybasic carboxylic acid and having terminal hydroxyl groups and (2) a diol compound having a bisphenol skeleton and represented by the general formula (I), in which formula (I), R1 and R2 represent a hydrogen atom or a lower alkyl group, A represents a C2-C4 alkylene group and m and n represent an integer of 1 to 20. |
