ABSTRACT:
Dye-receiving sheets for thermal recording which comprise a support and a dye-developing or receiving layer formed on the support. The layer is made of a composition comprising a dispersion of inorganic fine particles uniformly dispersed throughout a binder of a mixture comprising a first resin having good dye receptivity or good affinity for dyes and a second resin immiscible with the first resin. The binder mixture of two different types of resins allows microscopic interstices to exist at or along boundaries of the resins, through which interstices dye molecules penetrate and chemically combine with and/or adsorb on active sites of the inorganic particles and the first resin.
