Composition for forming intermediate film for laminated glass, intermediate film for laminated glass and laminated glass

摘要

The object of the present invention is to provide an intermediate film for laminated glass which prevents reductions of transparency and appearance property caused by permeation of moisture and water. The above object is attained by the present invention, i.e., a composition for forming an intermediate film for a laminated glass which comprises ethylene-vinyl acetate copolymer and a compound having alkyleneoxy group. The composition of the present invention enables the formation of an intermediate film for a laminated glass that restrains white spots from occurring by the permeation of moisture and water.
