Laminates, curing agents and substrates

Abstract

A laminate comprising a first film and a resin layer, the resin layer being disposed on one side of the first film and formed of a curable resin composition; the curable resin composition comprising three or more (meth)acrylate resins, a photopolymerization initiator, a thermosetting resin, and a colorant; the (meth)acrylate resin comprising: a carboxyl-containing resin (A) with a weight average molecular weight of 2000 or more and less than 8000, a carboxyl-containing resin (B) with a weight average molecular weight of 8000 or more and less than 14000, and a carboxyl-free resin (C) with a weight average molecular weight of 2000 or more and less than 8000; and, relative to 100% by mass of the total solids of the (meth)acrylate resin, the content of the carboxyl-containing resin (B) in the curable resin composition, calculated in terms of solids, is 30% by mass or more. After the aforementioned laminate is exposed and the aforementioned resin layer is cured, the resin layer peeled off from the first film is formally cured by light and / or heat to form a cured product. In the cured product, the skewness Rsk (µm), the maximum peak height Rp (µm), and the maximum valley depth Rv (µm) of the surface in contact with the aforementioned first film satisfy the following relationship: -3≦Rsk≦-1, and 2≦Rv / Rp≦5.
