| 摘要 |
The present invention relates to a method for indirectly coating polyols for a polyurethane-based adhesive sheet using a paper base, which is designed with a recipe for an adhesive solution mixed with polyols that yields good tightness between a paper base and a polyurethane-based adhesive layer, prevents the ingress of water into the surface of the paper base, and generates good adhesive force between the paper base and the surfaces of the adhesive layer. The method of the present invention is a method for indirectly coating polyols for a polyurethane-based adhesive sheet, which uses a paper base and a polyurethane-based adhesive layer stacked on at least one surface of the paper base, and a release film laminated onto the adhesive layer. The method comprises a step of forming the polyurethane-based adhesive layer by coating and hardening the solution mixed with polyols onto the release film, and a step of combining the polyurethane-based adhesive layer with the surface of the paper base and printing the polyurethane-based adhesive layer. |
