Abstract
Disclosed are polyester substrates or sheets laminated with an acrylic film and having exceptionally improved resistance to surface deterioration on weathering. These laminates are especially suited for use in applications such as windows, signs, solar collectors, green house covers and the like which are subject to extended periods of outdoor exposure. Typical polyesters include modified poly(ethylene terephthalate), and modified poly(1,4-cyclohexylenedimethylene terephthalate) such as those of terephthalic acid with ethylene glycol and 1,4-cyclohexanedimethanol, e.g., poly(69/31 molar-ethylene/1,4-cyclohexylenedimethylene terephthalate) and poly(65/35 molar-1,4-cyclohexylenedimethylene/ethylene terephthalate). The acrylic polymer films suitable forlamination to the polyester sheeting are homopolymers and copolymers prepared from either or both of the monomers H.sub.2 C.dbd.CHCO.sub.2 R and H.sub.2 C.dbd.C(CH.sub.3)CO.sub.2 R.sup.1 wherein R and R.sup.1 are each selected from C.sub.1 -C.sub.12 linear or branched alkyl groups.
