Abstract
An interlayer comprised of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive. The use of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive reduces or minimizes the optical defects (such as high color or yellowness and increased haze) caused by discoloration of the pigment without sacrificing other characteristics of the interlayer.
