1. A polyurethane resin obtained by a reaction between a polyisocyanate component comprisingpolyisocyanate component consisting of 1,4-bis(isoeyanatomethyl)cyclohexane consisting of 80-93% by mole of trans isomers and the remaining 7-20% by mole of cis isomers, wherein the cis and the trans isomers equal 100% by mole, andan active hydrogen compound component,wherein the active hydrogen compound component comprises at least one component selected from the group consisting of:
- a polyol component having two or more hydroxyl groups, a polythiol component having two or more mercapto groups, and a polyamine component having two or more amino groups.

6. A polyurethane resin obtained by a reaction between a polyisocyanate component and an active hydrogen compound component, wherein the polyisocyanate component comprises:
-
1,4-bis(isocyanatomethyl)cyclohexane consisting of 80-93% by mole of trans isomers and the remaining 7-20% by mole of cis isomers wherein the cis and the trans isomers equal 100% by mole and a polyisocyanate other than the 1,4-bis(isocyanatomethyl)eyclohexane; the active hydrogen compound component comprises; a high-molecular-weight polyol, an active hydrogen compound comprising a hydrophilic group and a chain extender; and first, the polyisocyanate component is allowed to react with the high-molecular-weight polyol and the active hydrogen compound comprising a hydrophilic group to prepare an isocyanate group-terminated prepolymer, and subsequently, the isocyanate group-terminated prepolymer and the chain extender are allowed to react to thereby obtain an aqueous polyurethane resin. - View Dependent Claims (7, 8)
