Abstract (en)

[origin: EP0870623A1] A recording material (I) having at least one colour receiving layer (A) for absorption of a water-soluble dye solution, in which the layer (A) contains (i) an epoxide-crosslinkable, carboxylic acid group-containing, cationic copolymer (II); (ii) an epoxide-containing metal oxide (III); and (iii) a water-soluble polymer (IV). Also claimed is a process for the production of (I), by making a coating solution from copolymer (II), metal oxide sol (III) and polymer (IV), coating this solution onto a substrate material, gelling and then drying to form layer (A).
