Abstract
Sustained-release composite particles having improved dispersion stability and improved sustained-release properties, and exhibiting longer-term effects, a method for producing the sustained-release composite particles, a dry powder comprising the sustained-release composite particles, and wallpaper comprising the sustained-release composite particles. The sustained-release composite particles comprise core particles containing at least one type of polymer and at least one type of functional component, and micronized cellulose coating at least a part of the surface of the core particles, the core particles and the micronized cellulose being inseparable from each other.

Sustained-release composite particles, comprising:
- active core particles comprising a mixture of at least one polymer and at least one functional component, and,
- an inert coating on the surface of the inert core particles,
- the inert coating consists essentially of micronized cellulose,
- the micronized cellulose is uniformly coated on the surface of the inert core particles,
- the at least one functional component is selected from the group consisting of an antifungal agent, a perfume, a fertilizer, a pesticide, a plant activator, a plant life extender, a pest and animal repellent, a soil penetrant, a nutrient component, a plant hormone, an antibacterial substance and combinations thereof, and
- the active core particles and the micronized cellulose of the inert coating being inseparable from each other.
