An electronic circuit having an electrically conductive pattern formed on a substrate (1) and having on at least one surface of the substrate a film (5) obtained from a soluble polymerizable oligomer of the formula:
wherein D is
wherein M is -C.C-, -C≡C-C≡C-. -0-.
wherein R is an alkyl or aromatic group; wherein A is an aromatic group; wherein x is the number of appendant acetylenic groups and is an integer greater than two but less than 30, z is either zero or an integer, and y is an integer with the sum of y and z equal to x; and wherein n is an integer from 1 to 10. The substrate is coated by applying the above composition to the substrate and then hardening the composition by further polymerization. Preferred compositions contain the above described oligomer and certain plasticizers and/or toughening agents.
