The present invention relates to a coating particle containing a nuclear particle covered with a coating layer, and in the coating particle, the coating layer is a layer containing hydroxyalkyl cellulose and a binder.

Coated particle and method for producing coated particle

Hydroxypropyl cellulose particles which contain 50-100 weight % of particles with a particle size that is larger than 150 &#x3bc;m and not larger than 355 &#x3bc;m.

Hydroxypropyl cellulose particles

A coating agent containing a hydroxyalkyl cellulose in which a content of hydroxyalkoxy groups within the hydroxyalkyl cellulose is within a range of 40 to 50% by mass, preferably a coating agent containing a hydroxyalkyl cellulose in which the content of hydroxyalkoxy groups is within a range of 40 to 50% by mass and also a viscosity of 2% aqueous solution at 20&#xb0; C. is within a range of 3.0 to 5.9 mPa&#xb7;s; and a solid preparation coated with the coating agent.
