Further, the coating material contains an emulsion resin having ≥65 mass% of (meth)acrylates having 1 to 2 carbon atoms in the ester mass, a brightening material and an alcohol compound having ≥175°C boiling point expressed by general formula (1). In formula (1), R represents a 5-12C alkyl group or a phenyl group, n represents 2 or 3 and m represents an integer 0 to 2. COPYRIGHT: (C)2004,JPO
