Abstract
Official abstract text for this publication.
A polyurethane resin composition includes a reaction product of an aliphatic polyisocyanate derivative having an average number of isocyanate groups of 2 or more; a long-chain active hydrogen compound including a hydrocarbon group having 12 or more and 30 or less carbon atoms and an active hydrogen group in combination; a cationic active hydrogen compound including an active hydrogen group and a cationic group in combination; and an acid compound capable of a salt with the cationic group. The concentration of the hydrocarbon group is 30% or more and 85% or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyurethane resin composition comprising: a reaction product of an aliphatic polyisocyanate derivative having an average number of isocyanate groups of 2 or more; a long-chain active hydrogen compound including a hydrocarbon group having 12 or more and 30 or less carbon atoms and an active hydrogen group in combination; a cationic active hydrogen compound including an active hydrogen group and a cationic group in combination; and an acid compound capable of a salt with the cationic group, wherein the concentration of the hydrocarbon group is 30% or more and 85% or less. 2. The polyurethane resin composition according to claim 1 , wherein the aliphatic polyisocyanate derivative includes an isocyanurate derivative of an aliphatic polyisocyanate. 3. The polyurethane resin composition according to claim 1 , wherein in the cationic active hydrogen compound, the cationic group is a tertiary amino group, the active hydrogen group is a hydroxyl group, and the cationic active hydrogen compound has two or more hydroxyl groups per molecule. 4. The polyurethane resin composition according to claim 1 , wherein the acid compound includes an organic acid. 5. A repellent comprising the polyurethane resin composition according to claim 1 . 6. A water repellent for fibers comprising the polyurethane resin composition according to claim 1 . 7. A stain-proof coating agent comprising the polyurethane resin composition according to claim 1 .
