Abstract

PURPOSE:To improve the clean degree in a radio wave darkroom, by applying a coating material of the emulsion system, the alcohol solvent system or the solventless system, which has not influence upon the composition of a wave sbsorber, to the surface of the wave abosrber with 10-50mu coating film thickness. CONSTITUTION:A coating material 2 of the emulsion system, the alcohol solvent ststem, or the solventless system, which has not influence upon the composition of a wave absorber 1, is applied to the surface of the wave absorber 1. At this time, when the clean degree is measured by a dust counter, it is found that applying of the coating material with 10-50mu thickness is best.
