Abstract
Abstract A painting method which comprises applying to a substrate an undercoating composition comprising from 10 to 500 parts by weight of an alkylated polycyclic aromatic compound containing no nitrogen, oxygen or sulfur to the extent detectable by elementary analysis and having a mean molecular weight measured by the VPO method of from 250 to 600 and an aromatic ring-forming proton density measured by the nuclear magnetic resonance method of from 35 to 80%, and 100 parts by weight of a urethane resin, said under-coating composition further containing a hardening agent and then applying an over-coating composition comprising a curable resin selected from the group consisting of an epoxy resin, a urethane resin, and an alkyd resin.
