Image recording sheet and method of image recording

Abstract

The receiving layer of the image recording sheet includes polysaccharides or derivatives thereof (eg, cellulose derivatives such as hydroxyalkyl cellulose) as film-forming resin components, and aliphatic dye fixatives (eg, aliphatic quaternary ammonium salts such as trimethyl ) C8-16 alkyl ammonium halide). The film-forming resin component may contain an oxyalkylene-based polymer (eg, polyethylene glycol). Image recording sheets are suitable for the method of forming an image on the receiving layer by the action of heat. The receiving layer may be untransferred or transferred. The transferable image recording sheet includes a substrate and a transfer layer, the transfer layer is formed on the substrate and is peelable from the substrate and contains at least a receiving layer, wherein the transfer layer is transferable to a transfer support. The receiving layer may contain resin particles for hot melt bonding. This image recording sheet and related method of forming images exhibit high color quality and color density, and can prevent the generation of harmful substances even by heating.

Description

technical field

[0001] The present invention relates to an image recording sheet on which an image formed by means of, for example, an inkjet printer can be recorded and which can suppress generation of harmful substances due to heating, and to an image forming method or image transfer using the image recording sheet method, and a method of suppressing the generation of harmful substances due to heating. Background technique

[0002] Thermal recording systems, particularly inkjet recording systems and sublimation dye transfer recording systems, are used for recording images because they are easily applied to production for preparing color images and are excellent in print quality. These recording systems require high color density on image recording sheets. On the other hand, there is known a transfer recording system comprising using the above-described recording system (specifically, an inkjet recording system) on a receptor layer of an image recording sheet, bringing the...
