Abstract
It is an object of the present invention to provide an interlayer film for a laminated glass not allowing visual identification of persons or objects behind the glass while transmitting a certain amount of visible light and having an excellent heat insulating property. The present invention is an interlayer film for a laminated glass, which comprises a polyvinyl acetal resin, a plasticizer, a dispersant, and titanium oxide particles, the titanium oxide particles being dispersed so as to have an average long diameter of 0.4 to 2 μm and a dispersion density of 2.0×105 to 7.0×105 particles/cm2.
