Abstract
The present invention aims to provide an interlayer film for a laminate glass to obtain a laminate glass which is excellent in transparency, heat-shielding property, and electromagnetic wave transmittance even if the laminate glass is produced by sandwiching the interlayer film for a laminate glass with one pair of glasses, and which is not deteriorated in the visible light transmittance and the initial optical properties and is excellent in weathering-resistance after the test even if a durability test to light is run for the above-mentioned laminate glass.
