Sheet for heat exchange

A sheet for heat exchange elements comprising at least a laminate of a porous base material and a resin layer,

• the resin layer containing at least polyvinylpyrrolidone and/or a vinylpyrrolidone copolymer and a urethane resin,
• wherein the resin layer contains an acrylic resin and
• a content of the acrylic resin is 2 mass % or more and 13 mass % or less relative to 100 mass % of the entire resin layer,
• wherein a content of the polyvinylpyrrolidone and/or vinylpyrrolidone copolymer is 50% by mass or more and 95% by mass or less relative to 100% by mass of the entire resin layer, and wherein a content ratio between the polyvinylpyrrolidone and/or vinylpyrrolidone copolymer, and the urethane resin (content (mass %) of the polyvinylpyrrolidone and/or vinylpyrrolidone copolymer/content (mass %) of the urethane resin) is 1.0 or more and 9.0 or less,
• wherein the acrylic resin has a crosslinked structure comprising a structure as represented by either chemical formula (I) or (II) given below:
• wherein R1 and R2 are each an alkyl chain having a length in the range of C1 and C5 and X1 to X6 are each an appropriate atom or molecular structure, and
• wherein R1 to R4 are each an alkyl chain having a length in the range of C1 and C5 and X1 to X8 are each an appropriate atom or molecular structure.
