    • A safe and low cost process for forming a black matrix for a color filter, which process provides high light screening properties and is suitable for panel processing. The process comprises the steps of providing a transparent substrate having provided thereon an aqueous resin layer containing physical development nuclei; supplying a developer for physical development on the aqueous resin layer; superposing a donor sheet containing a metallic compound comprising metal ions on the aqueous resin layer via the developer for physical development; and precipitating a metal of the metallic compound in the aqueous resin layer by physical development. Furthermore, the aqueous resin layer may or may not be patterned.

    • A photosensitive element comprising a temporary support having thereon an aqueous resin layer which contains at least one kind of fine particles having an average particle size or agglomerated particle size of 1 to 10 .mu.m. The fine particles impart a roughened surface to the aqueous resin layer. Furthermore, a photosensitive insulating resin layer is provided on the aqueous resin layer. Also disclosed is an insulating resin image having a roughened surface which is prepared by a process comprising the steps of providing the above-described photosensitive element, laminating the photosensitive element on an insulating substrate, and pattern exposing and developing the photosensitive insulating resin layer. Also disclosed is a process for producing an multilayer printed wiring board comprising the steps of laminating the above-described photosensitive element on an insulating substrate having thereon a first wiring pattern, forming via holes in the photosensitive insulating resin layer, depositing a conductive material on the photosensitive insulating resin layer and in the via holes, and forming a second wiring pattern on the insulating resin layer which is interconnected to the first wiring pattern through the via holes.
