Abstract
A multilamp photoflash device comprising an outer housing containing a plurality of flashlamps and means for sequentially flashing the flashlamps of the device and having an antistatic coating on the surface of the outer housing is provided. The antistatic coating comprises an anionic surfactant and a deliquescent salt. A method for inhibiting electrostatic charge buildup in a multilamp photoflash device comprising an outer housing containing a plurality of flashlamps and means for sequentially flashing the flashlamps of the device is also provided. The method includes applying an antistat solution comprising an anionic surfactant and a deliquescent salt dissolved in a solvent to the surface of the outer housing of the multilamp photoflash device and evaporating the solvent from the antistat solution on the surface of the outer housing so as to form an antistatic coating thereon. The coating comprises the anionic surfactant and deliquescent salt components of the antistat solution.
