Abstract
The present invention relates to an abrasive disk that is excellent in workability and stability and has a low degree of fatigue applied to workers and tools, and a process for producing the same. The abrasive disc is excellent in stability by virtue of a high adhesive strength of each layer, has high flexibility, elasticity, and adhesiveness, and is lightweight per unit area. Thus, it has a low degree of fatigue applied to workers and expensive tools. In addition, according to the above production process, the abrasive disk can be continuously mass-produced.
