Abstract:
A recording material for recording aqueous inks, said recording material comprising:(i) a temporary substrate, said temporary substrate selected from the group consisting of a) a paper impregnated with silicones, b) a paper coated with silicones, c) a paper impregnated with chromium compounds, d) a paper coated with chromium compounds, e) a plastics film coated with silicones, f) and a paper coated with silicone-free synthetic polymers, said silicone-free synthetic polymers selected from the group consisting of polyethylene, polypropylene, polyesters and copolymers thereof, and cellulose derivatives;(ii) a contact adhesive layer arranged on said temporary substrate;(iii) a porous ink absorption layer arranged on said contact adhesive layer, said porous ink absorption layer comprising from 5% to 40% by weight of film-forming binder, and from 60% to 95% by weight of fine thermoplastic particles having a mean particle size of from 0.5 .mu.m to 40 .mu.m;said porous ink absorption layer convertible by heat into a cohesive self-supporting film of said thermoplastic particles fused together such that the adhesion of said contact adhesive layer to said temporary substrate is less than the adhesion of said contact adhesive layer to said self-supporting film, said temporary substrate material removable at room temperature from said contact adhesive layer and said self-supporting film with a separation force of from 0.10 N/50 mm to 2.0 N/50 mm sample width.
