Abstract
Abstract Dye-receiving sheets for heat transfer recording comprising on a substrate, a dye-receiving layer consisting essentially of a cured product of an acrylate having two acrylic or methacrylic unsaturated bonds. The sheet is used in combination with a dye transfer sheet comprising a sublimable dye, and has a high affinity for the dye and a high heat resistance without bleeding of the dye.
