    摘要: A flexible printed-circuit board is covered imagewise with a polymer film as a cover layer to improve the flexibility of the board. The cover layer is formed by laminating a photoprintable, photosensitive layer supported on a flexible support to the surface of a flexible printed-circuit board, exposing the photosensitive layer imagewise to light to form a polymer image in the layer and removing the unexposed areas of the layer to leave an imaged polymer film on the surface of the board. The formation of the cover layer can be easily conducted by a continuous operation.

    摘要: A color filter having excellent optical properties can be produced in high yield using a photo-sensitive composition comprising (a) a resin, (b) one or more pigments, (c) one or more monomers, and (d) a photoinitiator to form a film on a substrate, followed by exposure to light and development using a specific developer containing ##STR1## wherein R.sup.1 is C.sub.1-19 alkyl; and R.sup.2 is C.sub.1-19 alkylene.
