A phosphor paste composition is disclosed, which uses as an organic binder an acrylic polymer obtained by copolymerizing an alkyl methacrylate as a principal component with a specific amount of at least one monomer selected from unsaturated carboxylic acids and hydroxyalkyl (meth)acrylates. Also disclosed is a phosphor paste composition making use of a phosphor having a volume average particle size in a range of 1-7 µm, with particles having a particle size of 1-9 µm accounting for at least 60 wt.%. These phosphor paste compositions have excellent firing characteristics and provide phosphor coatings excellent in both light-emitting characteristics and resolution.
本发明公开了一种荧光粉浆料组合物,该组合物使用一种丙烯酸聚合物作为有机粘合剂,该丙烯酸聚合物是以甲基丙烯酸烷基酯为主要成分,与一定量的至少一种选自不饱和羧酸和羟基烷基(甲基)丙烯酸酯的单体共聚而成。此外,还公开了一种荧光粉浆料组合物,该组合物使用了体积平均粒径在 1-7 微米范围内的荧光粉,其中粒径为 1-9 微米的颗粒至少占 60%。这些荧光粉浆料组合物具有优异的烧结特性,并可提供发光特性和分辨率均优异的荧光粉涂层。
