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.

A polyolefin composition includes a polyolefin substrate having incorporated therein a nucleating agent and a filler, wherein the composition exhibits an impact strength of >35 in-lb measured according to ASTM D4226, and a coefficient of linear thermal expansion of <4.510E-05 in/in/ft measured according to ASTM D696. The polyolefin composition may further include one or more of an ultraviolet light absorber, a hindered amine light stabilizer, an antioxidant, a colorant, a flame retardant, and an antimicrobial compound. The polyolefin compositions may be useful for construction articles for outdoor use, for instance house siding, cladding, soffit or roofing.
