Example Embodiment
[0188] Example
[0189] Hereinafter, the present invention will be explained more specifically through examples and comparative examples, but the present invention is not limited to the following examples.
[0190] Hereinafter, the first embodiment and the second embodiment of the present invention will be explained more specifically through examples and comparative examples.
Example Embodiment
[0191] [Manufacturing Example 1]
[0192] Mix mXDI (m-xylylene diisocyanate) 45.5g, hydrogenated XDI (1,3-bis(isocyanate methyl)cyclohexane) 93.9g, ethylene glycol 24.8g, dimethylolpropionic acid 13.4g and as The solvent was mixed with 80.2 g of methyl ethyl ketone, and reacted at 70° C. for 5 hours under a nitrogen atmosphere to prepare a carboxyl group-containing urethane prepolymer solution.
[0193] Next, this carboxyl group-containing urethane prepolymer solution was neutralized with 9.6 g of triethylamine at 40°C.
[0194] Disperse the carboxyl group-containing urethane prepolymer solution in 624.8 g of water using a homogenous disperser, and perform chain extension reaction with 21.1 g of 2-[(2-aminoethyl)amino]ethanol to distill off the methyl ethyl ketone. Thus, a water-dispersed polyurethane resin having an acid group having a solid content of 25% by mass, an average particle size of 90 nm, and an acid value of 26.9 mgKOH / g was obtained.
[0195] Next, γ-(2-aminoethyl)amino...
Example Embodiment
[0196] [Manufacturing Example 2]
[0197] The water-based polyurethane resin of Production Example 2 was obtained in the same manner as Production Example 1 except that the polyamine compound of Production Example 1 was changed to the following compound.
[0198] Polyamine obtained by dropping hydrogenated XDI (97.1 g of 1,3-bis(isocyanate methyl)cyclohexane) and 93.6 g of dimethylethanolamine, mixing, and reacting under a nitrogen atmosphere at 60°C for 2 hours Compound.
