Title:
BLOCK POLYISOCYANATE COMPOSITION AND METHOD FOR PRODUCING THE SAME, RESIN COMPOSITION, RESIN FILM AND METHOD FOR PRODUCING THE SAME, AND LAMINATE
Document Type and Number:
Japanese Patent JP2023070109
Kind Code:
A
Abstract:
To provide a resin film which is excellent in curability when baked at low temperatures of 90°C or lower when used as an aqueous coating composition, and is excellent in coated film appearance, water resistance and recoat adhesion of a resin film obtained after curing.SOLUTION: A resin film has an urethane bond derived from polyisocyanate obtained from aliphatic isocyanate and/or alicyclic isocyanate, an urea bond, a hydrophilic group, and a structure represented by the following general formula (I), wherein a molar ratio (urethane bond/urea bond) of the urethane bond to the urea bond is 95/5 to 30/70.SELECTED DRAWING: None
