  • Vinyl chloride-based resin latexes, processes for producing the same, and thermal transfer image-receiving sheet obtained using the same
    Patent number: 8932985
    Abstract: A vinyl chloride-based resin latex which froths little when unreacted monomer remaining in the latex are recovered under heat and reduced-pressure conditions, and a thermal transfer image-receiving sheet which has satisfactory water resistance, does not yellow during storage, and gives images having excellent durability and light resistance. The invention provides a vinyl chloride-based resin latex contains a copolymer containing a vinyl chloride and an epoxy-group-containing vinyl or contains vinyl chloride, an epoxy-group-containing vinyl, and a carboxylic acid vinyl ester, wherein a content of the epoxy-group-containing vinyl is 0.1% by weight or more but less than 3% by weight, and wherein the latex contains no surfactant, and has a solid concentration of 25% by weight or more; a process for producing the latex; and a thermal transfer image-receiving sheet obtained using the latex.
