There is provided a film having use of impact absorption capable of protecting a panel from impacts when the impacts are given to a display device, a window since it has an excellent ability to absorb impacts given to a surface of a display device, a window, or equivalent base plates. The impact absorption layer having a thickness of 30 &#x3bc;m or more has a hardness of 20 to 100 as measured at a room temperature using an Asker C hardness tester. Also, the film having use of impact absorption has excellent impact resistance and includes at least one layer, wherein the film includes at least one impact absorption layer having a hardness of 20 to 100 as measured at a room temperature using an Asker C hardness tester, the impact absorption layer having the total thickness of 30 &#x3bc;m or more.

Impact absorption layer having excellent impact resistance and film having use of impact absorption comprising the same

The present invention provides a method for preparing a conductive pattern, comprising a pattern forming step of forming a conductive pattern on a substrate; and a blackening processing step of blackening the surface of the conductive pattern by immersing the conductive pattern in an aqueous solution containing reducing metal ions to oxidize the surface of the conductive pattern, and a conductive pattern prepared therefrom.

Method for preparing conductive pattern and conductive pattern prepared by the method

Disclosed is a method for making a film assembly used in a PDP filter positioned on the front surface of a PDP, a film assembly manufactured by the method, and a PDP filter using the film assembly. The method includes providing a roll of an EMI film formed on a surface of a long transparent polymer resin film with a predetermined spacing and mounting the wound roll of the EMI film on a first feed roller; providing a roll of at least one long transparent functional film capable of covering at least partially the effective screen portions of the EMI film and mounting the wound roll of the functional film on a second feed roller which is spaced a predetermined distance from the first feed roller; and integrating the EMI film with the functional film by feeding them into a gap between the first and second compression rollers.
