摘要： An object of the invention is to provide a composition having excellent heat resistance and excellent adhesiveness. Moreover, another object is to provide a cured product obtained by curing the composition and a laminate containing the cured product. Furthermore, another object is to provide a heat-resistant material, a heat-resistant member, an electronic material and an electronic member each containing the composition. The objects are achieved by providing a composition including: a (meth)allyl group-containing maleimide compound having a structure having one or more benzene rings, one or more groups having a (meth)allyl group and one or more groups having a maleimide group; and a hydroxy group-containing maleimide compound having a structure having one or more benzene rings, one or more groups having a hydroxy group and one or more maleimide groups.

摘要： An object is to provide a crosslinkable resin composition having mechanical strength and capable of exhibiting flexibility, repairability, and remoldability in a low-temperature region including room temperature and contributing to prolongation of the life of the cured product itself and a decrease in waste. Specifically, used is a crosslinkable resin composition which can form a cured product having a phase-separated structure formed of a continuous phase and a discontinuous phase and in which the discontinuous phase has higher tensile elastic modulus than the continuous phase, and the continuous phase containing a reversible bond. In particular, in the crosslinkable resin composition, preferably, the continuous phase contains the reaction product of a resin component A containing the reversible bond with a curing agent, the discontinuous phase contains the reaction product of a resin component B with the curing agent, and the phase-separated structure contains the reaction product of the continuous phase and the discontinuous phase with the curing agent.
