    摘要： The present application provides a thin film mask including a first layer and a second layer; the first layer and the second layer are arranged in layer configuration; the second layer includes an adhesive film; under irradiation of an ultraviolet light source and with a thickness of the first layer being 200 µm or less, an absorption coefficient of the first layer is ≥ 20%, wherein a wavelength of the ultraviolet light source is 355 ± 15 nm; or under irradiation of a green light source and with the thickness of the first layer being 200 µm or less, the absorption coefficient of the first layer is ≥ 20%, wherein a wavelength of the green light source is 530 ± 15 nm; or under irradiation of an infrared light source and with the thickness of the first layer being 200 µm or less, the absorption coefficient of the first layer is ≥ 20%, wherein a wavelength of the infrared light source is 1045 ± 20 nm; and a visible light transmittance of the first layer is ≤ 90%. The optical properties are utilized by the thin film mask provided by the present application, less power for the light source is required and the cost can be saved comparing with a common thin film. Further, by the patterning content formed by a light source with low power consumption, and the cost of the adhesive film is low. A complicated process is not needed to be matched with to achieve the patterning process, and cost reduction and efficiency increase are achieved.

    摘要： An object of the present invention is to provide a flexographic printing plate precursor in which reproducibility of microcells is improved in a case of being made into a flexographic printing plate, and durability of independent dots is improved, and a manufacturing method of a flexographic printing plate using the flexographic printing plate precursor. The flexographic printing plate precursor of the present invention includes, in the following order, an infrared ablation layer, a photosensitive resin layer, and a support, in which a content of a photopolymerization initiator contained in a surface layer region of the photosensitive resin layer from a surface on a side in contact with the infrared ablation layer up to 100 µm in a thickness direction is larger than a content of a photopolymerization initiator contained in a remainder region of the photosensitive resin layer, which is closer to the support side than the surface layer region.

    摘要： A method of making a structure having a patterned a base layer and useful in the fabrication of optical and electronic devices including bioelectronic devices includes, in one embodiment, the steps of: a) providing a layer of a radiation-sensitive resin; b) exposing the layer of radiation-sensitive resin to patterned radiation to form a base layer precursor having a first pattern of exposed radiation-sensitive resin and a second pattern of unexposed radiation-sensitive resin; c) providing a layer of fluoropolymer in a third pattern over the base layer precursor to form a first intermediate structure; d) treating the first intermediate structure to form a second intermediate structure; and e) selectively removing either the first or second pattern of resin by contacting the second intermediate structure with a resin developing agent, thereby forming the patterned base layer. The method is capable of providing multilayer articles having almost any shape at high resolution without the need for expensive or damaging mechanical or laser cutting.
