Abstract: PROBLEM TO BE SOLVED: To improve the water resistance and humidity resistance of a recording material by adding a cationic mixed polymer having an epoxy crosslinkable carboxyl group, an epoxidized metal oxide and a water-soluble polymer to an inking layer. SOLUTION: An inking layer contains a cationic mixed polymer having an epoxy crosslinkable carboxyl group, a water-soluble polymer and epoxidized metal oxide. 30-60 wt.% of the epoxy crosslinkable carboxyl group-containing mixed polymer, 30-60 wt.% of the epoxidized metal oxide and 10-40 wt.% of the water-soluble polymer are pref. contained. The epoxy crosslinkable carboxyl group-containing cationic mixed polymer pref. has a structural formula represented by formula (wherein M is a carboxylic acid monomer; Z is a vinyl monomer, A is oxygen or nitrogen; R1 is H or CH3 ; R2 is a 2-8C alkyl group; R3 is CH3 , C2 H5 , C3 H7 or C4 H9 ; X is chloride or bromide and a is 10-50, 0-20 or 50-90 mol.%). In an example, a film layer is water-impermeable and forms a good image after a water-resistant test result.

Abstract: PROBLEM TO BE SOLVED: To provide a new recording material, which includes a layer containing powder having silica as a basis, the water resistance of which is improved, which shows a high resolution, the self-adhesion of which to a printing face is low and which can be properly employed to almost all the ordinary kinds of printers. SOLUTION: The powder-containing recording material includes an ink accepting layer. The ink accepting layer includes the following components such as an ink fixer made of the mixture of a water-soluble cationic polymer and a water-insoluble cationic polymer, a soluble plasticizer, polymer particles each having the glass transition temperature of below 25 deg.C and silica particles, the surface of each of which is modified by alkyl silane.

Abstract: Pigmented recording material with a color-receiving layer containing a silicon dioxide dispersion obtained by surface modification with vinyl-, (meth)acryl- or 1-8C alkyl-trimethoxy- or -triethoxy-silane (plus cationic color-fixing agents, plasticizer and optional polymer dispersion). Pigmented recording material with a color-receiving layer containing (a) 5-25 wt.% polymeric color-fixing mixture of water-soluble and -insoluble cationic polymers, (b) 5-20 wt.% water-soluble plasticizer, (c) 0-20 wt.% polymer dispersion with a glass transition point below 25 degrees C and (d) 30-80 wt.% silicon dioxide dispersion obtained by surface modification with alkylsilanes of formula (1), using a (SiO2 dispersion):(alkylsilane) ratio of (1:1)-(9:1). R1Si(OR2)3 (1) R1 = vinyl, (meth)acryl or 1-8C alkyl; and R2 = methyl or ethyl.

Abstract: 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).
