Title:
AQUEOUS DISPERSION COMPOSITION OF OLEFIN-BASED THERMOPLASTIC RESIN
Document Type and Number:
WIPO Patent Application WO/2023/063401
Kind Code:
A1
Abstract:
Provided is an aqueous dispersion composition of an olefin-based thermoplastic resin having excellent heat-sealing ability. More specifically, provided is an aqueous dispersion composition that is of an olefin-based thermoplastic resin and that contains a water-based dispersion medium, the olefin-based thermoplastic resin, a nonionic surfactant, a tackifying resin having a softening point of 50-180°C, and an olefin-based wax having a structure derived from polypropylene. The nonionic surfactant is an ethylene oxide-propylene oxide copolymer. The nonionic surfactant is contained in an amount of 2-10 parts by mass with respect to 100 parts by mass of the olefin-based thermoplastic resin.
