Abstract
Abstract A curable coating composition for paints and printing inks, which contains an acrylic or methacrylic acid ester prepared by addition reacting a monocyclic phenolic compound such as resorcine with ethylene or propylene oxide to produce an adduct and then esterifying the thus-produced adduct with acrylic or methacrylic acid to prepare the acrylic or methacrylic acid ester.
