Title:
AQUEOUS DISPERSION-TYPE RESIN COMPOSITION AND COATING FILM
Document Type and Number:
WIPO Patent Application WO/2020/196433
Kind Code:
A1
Abstract:
The present invention relates to an aqueous dispersion-type resin composition for forming a coating film, wherein when the aqueous dispersion-type resin composition is dried for 12 hours at 25°C to form a film, and further dried for 4 hours at 35°C to achieve a coating film with a thickness of 230±170μm, the coating film satisfies the following conditions (1) and (2). (1): After the coating film has been immersed for 2 hours in a 25°C 5% ethanol aqueous solution, the water content of the coating film is 110% or less. (2): The coating film has a release property index, as indicated by the following formula (2a), of greater than 2.5, and an adhesive force of 0.5N/20mm or greater. Formula (2a): Release property index=(tensile breaking strength (MPa))/{adhesive force (N)/(film thickness (mm)×width (mm))}
