Title: Coating composition for fluorescent lamp
Inventor: TANIOKA SOJI
IPC: H01J61/46
Filed: 1991-12-04
Abstract: PURPOSE:To prevent a lamp beam from deteriorating due to generation of pinholes and bubbles by containing water soluble o-2, 3-dihydroxypropylcellulose (DHPC) as a binder, in a fluorescent lamp coating composition. CONSTITUTION:When water soluble DHPC is used as a binder for a fluorescent lamp coating composition, because of a small foaming property, a pinhole is prevented from being easily generated in a fluorescent material film. Since separation by sedimentation of a fluorescent material is eliminated with no generation of uneven coating because stability is excellent relating to salt resistance and pH fluctuation, a fluorescent lamp of large lamp beam is obtained. The water soluble DHPC can be easily synthesized by reaction to dihydroxy propyl chemical agent of cellulose, 3-chloro-1, 2-propanediol or chrysidol. An additive amount in the case of using the water soluble DHPC as the fluorescent material binder is desired 1% or more relating to the fluorescent material.
