摘要： 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.
