Abstract

1,179,398. Polymerizable coatings. FORD MOTOR CO. 26 June, 1967, No. 29348/67. Heading C3P. A circuit board is produced by applying to the surface of a polymeric board and/or to the surface of a copper circuit thereon a coating comprising a polymerizable liquid, a filler and acrylic acid or a substituted acrylic acid and curing the coating by subjecting it to an electron beam. Examples are given of coatings comprising methacrylic acid, methyl methacrylate, styrene, unsaturated polyester, pigment and silica.
