  • Patent number: 8778224
    Abstract: The present invention provides a fluorescent dye-silane hybrid resin manufactured by polycondensing an alkoxysilane bonded with a fluorescent dye with an organo-silane. More particularly, the present invention provides a fluorescent dye-siloxane hybrid resin that is manufactured by reacting a fluorescent dye having one or more functional groups with an alkoxysilane having an organic functional group to form an alkoxysilane bonded with the fluorescent dye and then polycondensing the alkoxysilane bonded with a fluorescent dye with an organo-silanediol and an organo-alkoxysilane having a thermocurable or ultraviolet-curable functional group without water. The fluorescent dye-silane hybrid resin has excellent thermostability, photostability, fluorescence characteristics, and processibility.
