    摘要: An image recording sheet having an image receiving layer comprising a polysaccharide or its derivative (e.g., cellulose derivative such as hydroxyalkylcellulose) as a film formation resin component and an aliphatic dye fixer (e.g., aliphatic quaternary ammonium salt such as trimethyl C8-16 alkylammonium halide). The film formation resin component may contain an oxyalkylene polymer (e.g., polyethylene glycol). The image recording sheet is suitable for image forming methods wherein heat is applied to the receiving layer, and the receiving layer may be of non-transfer type or transfer type. The transfer type image recording sheet may be comprised of a substrate and, detachably superimposed thereon, a transfer layer including at least a receiving layer, which transfer layer may be transferred to a transfer target. The receiving layer may contain hot melt adhesive resin particles. This image recording sheet and relevant method of image forming exhibit high color formation capability and realize high color formation density and, even when heated, can prevent generation of hazardous matter.

    摘要: A receptive layer of an image-recording sheet comprises a polysaccharide or a derivative thereof (e.g., a cellulose derivative such as a hydroxyalkyl cellulose) as a film-formable resin component, and an aliphatic dye fixing agent (e.g., an aliphatic quaternary ammonium salt such as a trimethyC 8-16 alkylammonium halide). The film-formable resin component may contain an oxyalkylene-series polymer (e.g., a polyethylene glycol). The image-recording sheet is suitable for a image-forming method utilizing a thermal action on the receptive layer. The receptive layer may be either non-transferable or transferable. The transferable image-recording sheet comprises a substrate and a transfer layer, and the transfer layer is formed on and separable from the substrate and contains at least a receptive layer. The transfer layer may be transferable to an object. The receptive layer may contain a hot-melt adhesive resin particle. Such an image-recording sheet or a method for forming an image ensures high color quality and color density, and can prevent the generation of a harmful substance even by heating.
