<p>1,166,934. Coated paper. DYNAMIT NOBEL A.G. 15 March, 1967 [15 March, 1966], No. 12240/67. Heading B2E. [Also in Divisions B5 and D2] A strengthened furnishing or decorative foil is produced by coating a formed paper web with a solution of a thermoplastic polyester formed by condensation of ethylene glycol, terephthalic acid and isophthalic acid and optionally neopentyl glycol, with the molar ratio of terephthalic to isophthalic acid residues between 70 to 30 and 30 to 70, and that of ethylene glycol to neopentyl glycol residues between 90 to 10 and 60 to 50. Suitable solvents are ethyl acetate, a 1:1 mixture of toluene and methylethylketone, a 1:1:1 mixture of ethyl acetate, xylene and cyclohexanone, chlorinated hydrocarbons such as trichloroethylene, a 60:40 mixture of phenol and tetrachloroethane, and a 50:50 mixture of xylene and butanone. The coating may be by dipping, brushing or lacquering on two sides or leaving one side partially untouched. A further covering layer of polyvinyl chloride or the same mixed polyesters can be applied as a lacquer, or by calendering, or as granules applied by melt coating. If the paper has been lacquered on both sides with the mixed polyesters and dried at 100‹ to 150‹C it sticks to wood without an adhesive.</p> |
