METHOD OF COATING SUBSTRATE, SUBSTRATE, COATING UNIT, PROCESS FOR PRODUCING LAMINATE AND LAMINATE

摘要

A method of coating a substrate that enables forming an adhesive layer on a surface of substrate smoothly without fluffing, does not need drying operation so as to ensure high efficiency and is free from problems attributed to organic solvents, such as sick house,; and a coating unit for use in the method. Further, a process for producing a laminate wherein the coating method is used; and a laminate obtained by the process. In particular, a method of coating a substrate, comprising coating a surface of substrate while being conveyed with a hot melt adhesive in heated molten form by means of a coating roll being rotated to thereby form an adhesive layer, wherein the direction of rotation of the coating roll is identical with the direction of conveyance of the substrate and wherein the peripheral speed of the coating roll is set for one 20% or more lower than or 20% or more greater than the speed of conveyance of the substrate so that the substrate is coated with the adhesive while causing the coating roll to slip.
