Abstract: The invention provides an imaging element comprising a support having thereon, in order, at least one imaging layer, at least one interlayer containing a lubricant which provides scratch-resistance and at least one outermost layer containing a different lubricant which provides abrasion-resistance and a method of processing the element. The element has increased durability, especially with regard to scratch- and abrasion- (especially photoabrasion-) resistance, whilst retaining performance and ease of manufacture. Preferably the element is for use in the manufacture of printed circuit boards or the production of printing plates, wherein abrasion and scratches are particularly acute.

Abstract: A patterned electrical conductor having improved conductivity and controllably high resolution track and gap widths is obtained by exposing, to a desired conductive pattern, a pressure-sensitive or photosensitive element comprising a support and a pressure-sensitive or photosensitive material coated thereon being sensitive to the exposure (e.g. the wavelength of exposing radiation) and capable of providing a latent image upon exposure, and then developing the exposed element to form a developed element having a metal (e.g. silver) image thereon and then electroless plating and/or electroplating the metal image with a second metal (e.g. silver) whilst subjecting the developed element to ultrasonic agitation.
