ORGANIC FINE PARTICLE

WIPO Patent Application WO/2022/009689

A1

Provided is an organic fine particle containing a core polymer and a shell polymer. The Tg value or melting point of the core polymer is 15°C or higher. The contact angle with water of the core polymer is 100° or more. All monofunctional monomers that constitute the core polymer are hydrophobic core monomers, homopolymers of which have a contact angle with water of 100° or more. The Tg value or melting point of the shell polymer is lower than the Tg value or melting point of the core polymer. The contact angle with water of the shell polymer is less than 100°. All monofunctional monomers that constitute the shell polymer are water-insoluble shell monomers, homopolymers of which are water-insoluble. Also provided is a water-repelling agent composition which is obtained using the organic fine particle and can impart a substrate with excellent water repellency.
