ABSTRACT:
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.
