Pigment-attached phosphor.

摘要

A pigment-attached phosphor in which pigment particles are attached to the surfaces of phosphor particles by a binder, the binder being 0.01 to 1.0 parts by weight and preferably 0.05 to 0.80 parts by weight of gelatin and 0.01 to 0.5 parts by weight and preferably 0.02 to 0.40 parts by weight of urea resin, all against 100 parts by weight of phosphor, the weight ratio of the gelatin and urea resin being within a range of 1:1 to 10:1 and preferably 1:1 to 8:1. The gelatin and urea resin ensure a strong and better attachment of the pigment particles to the surfaces of the phosphor particles.
