O A dry-film, laminable photoresist of at least two layers, comprising:n a) a first layer of a photoresist layer, said first layer becoming more or less soluble in an aqueous alkaline solution or organic solvent after exposure to actinic radiation, and (b) a second layer, adjacent and adhered to a surface of said first layer, of a laminable crosslinked or crosslinkable organic polymer which is soluble in an aqueous alkaline solution or organic solvent. n The use of a thermoplastic, crosslinked or crosslinkable integral adhesive layer on the dry-film photoresist layer improves the properties and performance of the photoresist. |
