<P>PROBLEM TO BE SOLVED: To provide a lighting soundproof sheet which has so excellent soundproofness as to weaken the sound of rain and such a favorable lighting property that work can be performed without using illumination in the daytime and is used as an industrial material. <P>SOLUTION: The lighting soundproof sheet is a flexible sheet comprising a base material including a fibrous base fabric and a vibration damping resin layer arranged on the at least one surface of the base material. The vibration damping resin layer is formed to have a sea-island dispersion structure comprising an incompatible mixture of a compatible mixing resin component (a) containing a vibration damping property-imparting resin with an inorganic filler-containing resin component (b) having high specific gravity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
