Abstract: A method of removing a photoresist, a laminate, a method of forming a metallic pattern, a polyimide resin, and a stripper are provided. The method of removing the photoresist includes forming a release layer on a substrate, the release layer having a first surface and a second surface opposite to each other, wherein the first surface of the release layer is in contact with the substrate; forming a photoresist layer on the second surface of the release layer; and removing the release layer and the photoresist layer. The release layer is formed by a polyimide resin. The polyimide resin is obtained by performing a polymerization of tetracarboxylic dianhydrides, diamines, and phenolamines. The diamines include hydroxyfluorinated diamines, benzoic acid diamines, and aminotetramethyldisiloxanes.

Abstract: A composition, a method fabricating the infrared ray transmitting filter, and an infrared ray sensor are provided. When the composition forms a film with a thickness of 1 μm, transmittance of the film in a wavelength in a range from 400 nm to 700 nm is less than 4%, and transmittance of the film in a wavelength in a range from 900 nm to 1300 nm is more than 90%. The composition comprises an alkali-soluble resin at least containing an acrylic group, a carboxyl group, and a fluorene ring, a photoinitiator, an unsaturated monomer, a pigment mixture, and a solvent. The pigment mixture is formed by mixing a colorant dispersion and a pigment in a weight ratio from 60:40 to 70:30.

Abstract: The invention relates to a masking layer. The masking layer produced by coating a white-color photosensitive resin composition on a peripheral region of a transparent substrate, developing the white-color photosensitive resin composition to obtain a patterned composition layer, coating a gray-color photosensitive resin composition on the cured composition layer and developing the gray-color photosensitive resin composition, so that the gray-color photosensitive resin composition is cured to obtain the masking layer having an optical density (O.D.) of ≧3.5. The masking layer is adapted for use on a touch panel or a flat panel display device. The masking layer shows a white color appearance when viewed from outside and serves as a white color decoration around the peripheral region of the device. The masking layer further comprises a gray colored sub-layer to mask the electrical circuitry disposed beneath the masking layer.
