A dielectric coating composition that is screen printable and radiation curable is disclosed. The composition is composed of from about 10 percent to about 50 percent of an unsaturated thiolene prepolymer system, from about 0 percent to about 35 percent of an acrylated prepolymer system, from about 10 percent to about 40 percent of at least one crosslinking diluent monomer, from about 4 percent to about 18 percent of at least one plasticizer and from about 3 percent to about 12 percent of at least one nonshrinking monomer. The cured coating is sufficiently compliant at normal temperatures to avoid cracking upon flexure of thermal expansion of the substrate.

A flat multiconductor cable having a multilayer construction and especially suited for use in establishing interconnections between the cable conductors and a separate conductive array such as a similar flat cable is disclosed. Conductive ink, formed metal conductors or etched conductors can be deposited on a flexible substrate and covered by a dielectric covering in the form of an ultraviolet cured dielectric coating or a separate insulating film. The conductors can be covered by anisotropic conductive adhesive with the conductive adhesive in contact with the underlying conductors at exposed tap locations where no dielectric coating is deposited or where the dielectric coating has been removed. A separate conductive array can be positioned in registry with the tap locations and the conductive adhesive can be used both to secure the conductive array to the cable and to establish electrical continuity between corresponding conductors.
