Abstract
The invention intends to provide a method for preventing deterioration in quality of the primer layer resulting from spinning-off and reattachment of a primer liquid on forming a polyurethane primer layer on a substrate for an eyeglass lens or the like using a coating composition containing a moisture-curing polyurethane resin. The method for producing a laminate according to the present invention comprises performing spin-coating while a spin-coating apparatus is forcefully evacuated through the side wall and/or the bottom thereof, on producing a laminate by spin-coating the surface of a substrate with a coating composition containing a moisture-curing polyurethane resin. More preferably, the spin-coating apparatus comprises a top cover, a lower chamber, and a rotatable substrate supporting device installed in the lower chamber; exhaust ports are provided in the top cover and at the bottom of the lower chamber; and the substrate supporting device is housed in a cylinder member wherein the aperture of at the lower end is larger than the aperture at the upper end.
