    摘要： The surface of a web is coated with a dry coating powder. The coating powder has inorganic material and polymeric binder material. The polymeric binder material is selected in such a manner that when increasing the temperature above the glass transition temperature the ratio G″/G′ is at the most equal to the ratio G″/G′ in the glass transition temperature.

    摘要： A method and assemby is disclosed for manufacturing a two-layer coated paper web, the method comprising the steps of applying a coating furnish layer to at least one surface of said paper web, drying the applied coating furnish layer to a point allowing a next coating layer to be applied thereon. Onto the first coating layer is applied a second coating layer that is dried. The application of successive coating layers is continued until the desired coat thickness is attained. The coating layers are applied using a metering film transfer method operating without leveling of the applied coating layer by doctoring, whereby in at least one of said coating layers is used a furnish having a solids content of not less than 62%.
