An interlayer comprised of a thermoplastic resin, at least one luminescent pigment and a magnesium salt comprising a divalent magnesium ion and at least 2 carboxylate groups wherein the corresponding carboxylic acids of the carboxylate groups each have a pK.sub.a of less than about 4.80. The use of a thermoplastic resin, at least one luminescent pigment and a magnesium salt comprising a divalent magnesium ion and at least 2 carboxylate groups wherein the corresponding carboxylic acids of the carboxylate groups each have a pK.sub.a of less than about 4.80 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, such as adhesion.
