ABSTRACT:
A radiation sensitive composition containing a fluorescent substance dispersed therein, comprising (A) the fluorescent substance, (B) an organic polymer binder, (C) at least one optically crosslinkable compound selected from optically crosslinkable monomers and oligomers, and (D) an optically radical-generating agent which comprises (a) a 2,4,5-triaryl imidazole dimer, (b) an amino group-containing benzophenone photosensitizer, and (c) a thiol compound represented by the following formula (1): ##STR1## wherein Z is --O--, --S--, --NH-- or --CONH--. This radiation sensitive composition can provide a fluorescent screen having a larger film thickness and a higher display brightness and hence, will greatly contribute to increases in the size and precision of a fluorescent display device such as a plasma display panel.
