Fugitive colour fire retardant composition for aerial application |
(57) In a fugitive color fire retardant composition, the colorant initially colors the
composition to a hue which contrasts with the hue of ground vegetation. A non-fugitive
component is included in the colorant, in an amount sufficient to provide improved
aerial visibility when the composition is first aerially applied to the vegetation.
However, the amount of non-fugitive pigment is less than an amount which would prevent
the composition from fading after application to an acceptable hue.
