Abstract

1,226,407. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 12 June, 1968 [15 June, 1967], No. 25158/68. Divided out of 1,208,283. Heading B5N. [Also in Divisions B2, C2 and C3] Laminates comprise a sandwich between two sheets of asbestos, paper, cardboard, hardboard, plasterboard, metal or a synthetic resin, of a foamed resin of a phenolic resole derived from a mixture of phenolic compounds which contains a polynuclear diphenol of formula where # is a phenylene group which may be substituted by alkyl, alkoxy or hydroxyl groups at least one hydrogen atom being ortho or para to a hydroxyl group and #<SP>1</SP> is a phenylene group which may be substituted by alkyl or alkoxy groups or halogen atoms, the diphenol forming from 1/11th to 1/3rd of the total molar concentration of the mixture. The phenolic mixture may comprise phenol and
