<P>PROBLEM TO BE SOLVED: To make distribution of film thickness of coating film small by forming the coating film along the asperities of the surface of a web. <P>SOLUTION: A coating liquid for producing coated articles produced by coating and drying is designed to satisfy following four liquid physical property conditions: (A) in a drying process, after the solid content concentration in the coating liquid is increased to 15 mass% or more by drying the coating film in the drying step, or after the start of drying when the solid content concentration in the coating liquid is 15 mass% or more at the time of coating; (B) the shear viscosity of the coating liquid becomes 5 mPas or more for the shear rate of 10<SP>3</SP>sec<SP>-1</SP>or less; (C) the value obtained through dividing by the average viscosity the first differential coefficient, namely, the increase coefficient of the increase rate of the shear viscosity relative to the increase rate of the solid content concentration is 0.15 or more; and (D) the second differential coefficient, namely, an additional increase coefficient of the increase coefficient relative to the solid content is positive. <P>COPYRIGHT: (C)2007,JPO&INPIT |
