Abstract
A liquid composition which on exposure to actinic radiation polymerizes to form a heat-curable solid film adhesive, said composition comprising (A) a heat-curable phenol-aldehyde resol resin, (B) a photopolymerizable polyurethane or polyester having, on average, more than one polymerizable acrylic group per molecule, or a mixture of said polyurethane and said polyester, (C) a photopolymerization initiator for (B) and (D) a polyvinylacetal. The heat-curable solid film adhesive is used for bonding friction materials, such as brake linings, to metal.
