摘要:
The purpose of the present invention is to provide: a lamination method with which high membrane thickness precision can be obtained by reducing variations in substrate membrane thickness, the method being highly versatile and capable of limiting cost increases; and a laminate. This lamination method comprises a gluing process for conveying a substrate and a support with specified conveyance paths and gluing the support to the main surface of the substrate, and a curing process for curing the adhesive after the gluing process. The gluing process glues the substrate to the support by passing same successively between two or more pairs of nip rollers. The two or more pairs of nip rollers are set so that the nip distance of the pair of nip rollers disposed on the downstream side is equal to or less than the nip distance of nip rollers disposed on the upstream side.

Provided are a resin composition for laser engraving having excellent roll detachability and sheet appearance when the resin composition is subjected to calender processing, and a method for producing a flexographic printing plate precursor for laser engraving and a method for producing a flexographic printing plate, which use the resin composition for laser engraving. Disclosed is a method for producing a flexographic printing plate precursor for laser engraving, the method including, in the following order, a layer forming step of forming a relief forming layer using a resin composition for laser engraving, through sheet molding using a calender roll; and a crosslinking step of crosslinking the relief forming layer by means of heat, and obtaining a flexographic printing plate precursor for laser engraving having a crosslinked relief forming layer, in which the resin composition for laser engraving is a resin composition including a diene-based polymer, a thermal polymerization initiator, carbon black, and a filler other than carbon black.
