ABSTRACT:
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 .mu.m, with particles having a particle size of 1-9 .mu.m 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.
