The present invention further relates to an additive mixture comprising at least one compound of formula (A) and at least one UV absorber. The present invention also relates to the use of the additive mixture for increasing the optical properties of molded or extruded articles, including multilayer articles.

Background Art

[0002] Polycarbonate molded or extruded articles are known in the literature and are prepared for a number of applications. These articles are produced, for example, by extruding a composition comprising a polycarbonate. Coextrusion of the polycarbonate and, in addition, other compositions containing a relatively high proportion of UV absorber may optionally occur. However, polycarbonate has the disadvantage of being essentially UV - unstable per se.

[0003] To prevent the adverse effects of ultraviolet light on articles made from polycarbonate, various additives, such as hindered amine light stabilizers, UV absorbers, etc., are used. However, these additives or mixtures of these additives cannot significantly improve the stability of polycarbonate molded or extruded articles.

[0004] Accordingly, an object of the present invention is to overcome the above - mentioned disadvantages and to provide a polycarbonate comprising a composition having improved optical properties. It is particularly desirable to improve the optical properties of polycarbonate sheets and polycarbonate articles.

III-2) Shutters (e.g., roller shutters). III-3) Contours (window frames) of any shape. III-4) Glass substitutes, especially extruded sheets, architectural glazing (monolithic, twin or multi-wall), aircraft, schools, extruded sheets, window films for architectural glazing, trains, transportation, sanitary products, and greenhouses.

[0169] The currently claimed invention provides one or more of the following advantages: 1. Articles prepared by the use of a combination of at least one compound of formula (A), at least one UV absorber other than the compound of formula (A), and polycarbonate improve the optical properties of a polycarbonate sheet or polycarbonate article exposed to light.

[0170] 2. A polycarbonate sheet or polycarbonate article having improved optical properties with respect to exposure extends the lifespan of the polycarbonate sheet or polycarbonate article.

[0171] 3. The long-term effect of a polycarbonate sheet or polycarbonate article creates economic value.
