Abstract:
A method of forming a coating layer where a running web is coated with a PVA coating liquid containing polyvinyl alcohol and a coating liquid layer on said running web is dried to form the coating layer on said running web, the method comprising the steps of:adding polymer polysaccharide to said PVA coating liquid so that a density of the polymer polysaccharide is within the range between 0.05% and 0.5% by weight with respect to said PVA coating liquid;forming the coating liquid layer on said running web by coating said running web with said PVA coating liquid to which the polymer polysaccharide is added so that a temperature of said PVA coating liquid is within the range between 20.degree. C. and 40.degree. C. at the coating; anddrying the coating liquid layer after preliminarily drying the coating liquid layer on said running web so that a temperature of the coating liquid layer is maintained for at least three seconds at a temperature that is lower than the temperature of said PVA coating liquid by at least 3.degree. C.
