摘要： A grain aggregate is formed by bonding a plurality of cross-linking polymeric grains via a substance (binder) having a reactive functional group, and alternatively, the grain aggregate is formed by bonding at least two different types of a plurality of grains, thus providing the grain aggregate having the improved heat resistance, solvent resistance, strength and light-diffusing properties. Further, a light-diffusing agent made up of the grain aggregate has the improved light-diffusing properties. Therefore, when applying a light-diffusing mold article including the light-diffusing agent to, for example, a backlight of a liquid crystal display device, high brightness and a wide angle of visibility can be attained. Further, by spray drying of a dispersion liquid containing the grain aggregate, the grain aggregate can be produced with ease.

摘要： The present invention provides a thermosetting resin potting composition with low melt viscosity and good flowability even though it contains large amount of an inorganic filler containing sphere silica powder as a main component. With this construction, the present invention has solved the problem residing in the prior art that, when the content of an inorganic filler is increased, the viscosity of a potting composition is increased and its flowability is lowered. In the present invention, the sphere silica particles in the inorganic filler have at least one particle group, and the particle group has an average particle diameter of 0.01 to 10 &mgr;m and a coefficient of particle diameter variation of 10 percent or smaller. More preferably, the sphere silica particles have two or more particle groups. In this case, the average particle diameter of the larger particle group is 1.4 times or larger than that of its adjacent and smaller particle group.
