A heat-sensitive recording material having a substrate that carries on its first side at least one heat-sensitive recording layer having at least one dye precursor and at least one color acceptor. The dye precursor and color acceptor react with one another in a color-forming manner under the action of heat. On its second side the substrate has a backcoat containing calcium carbonate. The backcoat is formed of at least two layers, a first layer is applied closer to the substrate and a second layer is applied farther from the substrate. The first layer contains a first calcium carbonate and the second layer contains a second calcium carbonate that differs from the first calcium carbonate.

Heat-sensitive recording material with reverse face coating

An ink-jet recording paper with a paper substrate that has a coating on at least one side, wherein the coating contains binder and inorganic pigment, and wherein:

Ink jet recording material

A novel recording material for the inkjet printing process has a substrate and an ink receiving layer which is applied on at least one side of the substrate, the ink receiving layer containing an inorganic pigment and an ink fixative comprising at least two substances. The first substance is a polyamine epichorohydrin and the second substance is a polyvalent metal salt. This recording material is characterized in that the first substance is a medium-molecular, branched polyamine epichlorohydrin condensation product, the ratio of the first substance to the second substance is between 3:1 and 16:1, the pigment makes up at least 80 percent by weight with a Dparticle size (Malvern) ranging from 4 &#x3bc;m inclusive to 12 &#x3bc;m inclusive, and the ratio of ink fixative to pigment ranges from 1:2 inclusive to 1:6 inclusive. The invention is further directed to a method for recording by the discontinuous inkjet printing process which uses the novel recording material.

Inkjet printing recording material

A printing medium for the inkjet printing method having a substrate and an ink acceptor layer, which is applied to at least one side of the substrate, wherein the ink acceptor layer includes an ink fixing agent and an inorganic pigment. The ink fixing agent includes a medium molecular weight branched amine-epichlorohydrin condensate which includes at least 70% by weight of the total quantity of the ink fixing agent in the ink accepting layer, the inorganic pigment is present at least 80% by weight with a particle size in a range between 6 and 12 &#x3bc;m and the ink fixing agent to pigment ratio is in a range from 1:2 to 1:6.
