Problems solved by technology

In the case of using a UV-curable resin for the surface layer, there is a possibility that when curing is performed by ultraviolet irradiation, curing shrinkage easily occurs in the surface layer, thus causing strain between the base layer and the surface layer, resulting in deterioration of interlayer adhesion

Abstract

Provided are: a laminate having excellent flexibility in which interlayer adhesiveness is improved; and a conductive roller capable of sufficient pressure contact with another member when pressed against the other member. Specifically, there is provided a laminate comprising at least two energy ray-curable resin layers each formed by curing a resin composition with energy rays, wherein: the laminate comprises an energy ray-curable resin layer (1) and Energy ray curable resin layer (2); the first resin composition for forming the energy ray curable resin layer (1) includes an energy ray curable resin (A) having two The oxirane backbone of the above oxirane repeat unit.

Description

technical field [0001] The present disclosure relates to a laminate and a conductive roller. Background technique [0002] Conventionally, in a conductive roller having an elastic layer containing polyurethane, a technique of providing a UV curable resin as a surface layer on a base layer to suppress toner filming and the like is known. In the case of using a UV curable resin for the surface layer, there is a possibility that curing shrinkage easily occurs in the surface layer when it is cured by ultraviolet irradiation, thereby causing strain between the base layer and the surface layer, resulting in deterioration of interlayer adhesion. [0003] In order to improve the interlayer adhesiveness, a technique of using a urethane acrylate oligomer having a weight average molecular weight of 6000 or more and acryloylmorpholine in the surface layer is known (see, for example, PTL 1).
