Title:
URETHANE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/048240
Kind Code:
A1
Abstract:
Provided is a urethane resin composition which contains an aqueous dispersion of a urethane resin and a coloring agent and which can form a film which does not cause problems in terms of unpleasant odors and discoloration and does not cause cracking or a deterioration in mechanical properties such as tensile strength when the film is formed. This urethane resin composition contains (A) an aqueous dispersion of a urethane resin having an oxyethylene structure and (B) a coloring agent such as a pigment. The ratio of the particle diameter (D50) of the aqueous dispersion (A) of a urethane resin, at which the cumulative value in a volume frequency particle size distribution reaches 50%, and the particle diameter (D50) of the coloring agent (B), at which the cumulative value in a volume frequency particle size distribution reaches 50% [D50 of (B)/D50 of (A)] is 2/3 or less.
