The resinol on treatment with formaldehyde formed thermoplastic products, shining and varying in shades from reddish brown to jet black. The lacquer forming ingredient has been isolated and identified as laccol (3-heptadecadienyl catechol), confirmed by the preparation of its hydrogenated product and its derivatives.
