摘要

A recording material comprises paper containing cellulose fibers as the main component, with the elongation percentage of the paper in the cross direction thereof when immersed in water at 20 DEG C for 1 minute being 1.8 % or less, and is capable of repeated use without wrinkles forming in the paper. The paper includes a waterproofing agent either on its own or in combination with one or both of a water-soluble polymer and a sizing agent. To reuse the material as aqueous liquid comprising an image-removal acceleration liquid is applied to weaken the adhesive of ink to the paper and the images are stripped off the paper by an image peeling member under heat or pressure. Other parameters of the paper - the wet-dry tensile strength ratio, the penetration rate, the wetting-agent treated sizing degree, the wet stiffness and the short-time wetting elongation percentage - are specified.
