Abstract
An aspect of the present invention is a resin composition for a laminated glass interlayer used for forming a laminated glass interlayer. The resin composition for a laminated glass interlayer includes an ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer, and an inorganic filler (B). The volume-based cumulative 10% diameter (D10) of the inorganic filler (B) as measured by a laser diffraction scattering method is equal to or more than 0.1 μm and equal to or less than 10 μm.
Claims7
