Abstract
An image-receiving sheet having an opaque detection mark formed by coating a resin varnish comprising a resin, a low-boiling good solvent, and a high-boiling poor solvent, the detection mark being rendered transparent upon heating, the resin comprising a terpolymer of vinyl chloride, vinyl acetate, and vinyl alcohol monomers. By virtue of this constitution, before image formation, the detection mark has high opacity and can be detected in high sensitivity, that is, does not cause a lowering in infrared radiation transmission or reflectance properties before heating at the time of image information, while when an image is formed by means of a copying machine or a printer in high-processing electrophotographic system, thermal transfer system or the like, heating and application of pressure at the time of image formation erases the detection mark to such an extent that the detection mark is no longer visually noticeable.
