MANUFACTURING PROCESS FOR COATED POLYESTER FILM |
摘要 |
A biaxially oriented composite film includes a polyester substrate supporting one or more coatings on one or both surfaces of said substrate,
wherein the polyester substrate is a biaxially oriented film;wherein the one or more coatings is/are derived from a predominantly inorganic hardcoat coating composition including inorganic particles contained in a polymerisable predominantly inorganic matrix; and wherein the biaxially oriented composite film has been annealed at a temperature Ta (° C.) above Tg where Tg<Ta≦Tg+100 (° C.) for a time t after thermal equilibrium where 1 hour ≦t≦72 hours. A method of making the film is provided. |

1. A method of producing a biaxially oriented composite film comprising a polyester substrate supporting one or more coatings on one or both surfaces of said substrate, wherein said polyester substrate is a biaxially oriented film, said method comprising the steps of:
disposing on one or both surfaces of said polyester substrate said coating wherein said coating is derived from a predominantly inorganic hardcoat coating composition comprising inorganic particles contained in a polymerisable predominantly inorganic matrix; and subsequently annealing said biaxially oriented composite film at a temperature Ta (° C.) above Tg where Tg<Ta≦Tg+100 (° C.) for a time t after thermal equilibrium where 1 hour ≦t≦72 hours. |
