摘要:
This method makes it possible to form a fluorescent film (10) easily and efficiently on a glass plate (18), particularly on the face plate (8) of a cathode ray tube. A transfer material for its use is also provided. The method comprises the steps of, by use of the transfer material (7) in which at least thermally transferable phospher layers (11, 12 and 13) containing phosphers and thermally fusible binder are formed on a base film (3), transferring the patterns of the thermally transferrable phospher layers (11, 12 and 13) to the glass plate (8) one after another; and baking the glass plate (8) to remove the binder from the fluorescent film (10) and to form the fluorescence film on the glass plate. The transfer material has a thermally transferable phosphor layer (4) containing at least phosphs (1) and thermally fusible binder (2) on the base film (3).

The object of the present invention is to provide a glass composition which has a sufficient bonding strength for bonding a fluorescent film with a glass tube, does not hinder decomposition of the binder and is effective as an adhesive material and to provide a fluorescent lamp using the glass composition. The object can be achieved by a glass composition, represented by the general formula, xMO . yB2O3 . zM'2O3 . uM''O2 . vM'''2O5 in which M is at least one element of Mg, Ca, Sr, Ba and Zn, M' is at least one element of Al, Sc, Y and lanthanoid elements, M'' is at least one element of Ti, Zr, Hf, Th and Si, M''' is at least one element of Nb and Ta, x, y, z, u and v satisfy the relationships of 0
