<p>LUMINESCENT FOAM FLOATS AND METHOD Luminescent or light-emitting floats, such as seine floats, molded from pore-forming resinous compositions which contain an effective amount of a luminescent or phosphroescent pigment. The present floats contain the light-emitting pigment not only at the outer surface thereof but also inwardly thereof so that the removal or wear of surface portions of the float uncover interior portions which also contain said pigment.</p> |
