Abstract:
A method for drying, with drying air in a drying process, a coating film in manufacture of thermal-developable light-sensitive material formed by coating with a coating liquid that contains an organic silver salt, a reducer for silver ions, a polymer latex, and silver halide particles to a support being conveyed in a coating process, wherein:the drying process comprises: a chilling-zone step for cooling the coating film with cold air; a plane air cushion drying step for a first-stage drying of the coating film in a non-contact state while floating and supporting the support by supplying a hot drying air of a predetermined wind velocity to both sides of the support; a helical air cushion drying step for a second-stage drying of the coating film in a non-contact state while helically winding the support around a circumferential surface of a cylinder and floating and supporting the support by supplying the hot drying air from the circumferential surface of the cylinder to the coating film.
