Abstract
Provided is an interlayer film for laminated glass which produces a high contrast image under light radiation, is less susceptible to color changes, and allows for control of the adhesion, as well as a laminated glass including the interlayer film. The interlayer film includes a light emitting layer containing a polyvinyl acetal, a light emitting material having a terephthalic acid ester structure, and a potassium salt.
