  • Publication number: 20240118611
    Abstract: An object of the present invention is to provide a transfer film and a photosensitive composition, with which a film having excellent low moisture permeability and excellent scratch resistance can be formed. The transfer film of the present invention is a transfer film including a temporary support and a photosensitive layer, in which the photosensitive layer contains a polymer A and a compound ?, the polymer A has a repeating unit (a) having a carboxy group linked to a main chain by a linking group having 1 or more carbon atoms, and the compound ? has a structure b0 which reduces an amount of the carboxy group included in the polymer A by exposure.

  • Publication number: 20230059487
    Abstract: The present invention provides a photosensitive material with which a film having a low relative permittivity can be formed. In addition, the present invention provides a pattern forming method, a manufacturing method of a circuit wiring, a manufacturing method of a touch panel, and a transfer film, which are related to the photosensitive material. The photosensitive material of the present invention satisfies at least one requirement of the following requirement (V01) or the following requirement (W01). (V01) the photosensitive material includes a polymer A having a carboxy group and a compound ? which has a structure b0 in which an amount of the carboxy group included in the polymer A is reduced by exposure. (W01) the photosensitive material includes a polymer Ab0 which is the polymer A and further has the structure b0 in which the amount of the carboxy group included in the polymer A is reduced by exposure.
