Abstract

Process for obtaining liquid polyhydroxy compounds, soluble in solvents for lacquers, with a content of hydroxy groups of 3 to 10% by weight, characterized in that alkoxylated phenols of the formula **(See formula)** where R and R'signify the same or different residues and represent hydrogen or a methyl group and n signifies an integer from 1 to 3, they are reacted with formaldehyde, in the presence of mineral acids, at 50-150ºC, the molar ratio between phenol alkoxylated and formaldehyde from 1: 0.8 to 1: 1.5.
