Definitions

zinc benzoates are generally known as color acceptors in color-reactive recording materials.
the non-generic EP 1 375 182 A1 the zinc 4-nitrobenzoate, which is not identical to zinc salicylate, as a developer component in heat-sensitive recording materials.
zinc benzoates and also those color developers, which include the zinc salicylate proposed here are disclosed as components of color-reactive recording materials, without mentioning the possible embodiments of such color reaction layers or even production processes for forming recording materials with such color reaction layers received.
Subject of the US 4,257,935 A is a color-developing coating composition which, according to introductory passages, is to be used preferably for pressure-sensitive recording systems.
a coating composition will contain, in addition to zinc salicylate as a color acceptor, and starch and Latex as a binder, a clay pigment, the possible involvement in which there proposes coating composition composition explanatory description is not mentioned.
a SC (selfcontained) coating composition for forming a carbonless paper are disclosed for the zinc-salicylate as a color acceptor, a variety of possible components such as starch and polyvinyl alcohol as a binder and optionally also various pigments as possible fillers.
CB layers (coated back), as understood in the present specification, contain microcapsules in which dye precursors are present in a suitable solvent.
the application of a localized pressure to the CB coating causes the microcapsules to break up, resulting in a release of the previously encapsulated dye precursors.
the dye precursor from the microcapsules with the zinc salicylate as at least one color acceptor within the CF layer together it comes to forming a color reaction, which takes place exactly where the microcapsules were previously broken by the pressure exerted: usually this happens along a script line, which is formed by inscription by means of pen or typewriter.
an SC coating includes both encapsulated dye precursors and dye acceptors that react with these dye precursors upon release.
CF recording materials produced by the method proposed herein color-forming to be bonded CB recording materials having microcapsules which largely not in terms of size and the leuco dyes preferably used therein are restricted.
those microcapsules which have a wall material of melamine-formaldehyde resin with a preferred average capsule size in a range in particular of 4 to 6 ⁇ m are particularly well-proven.
Diisopropylnaphthalene oil KMC oil from Rütgers Novares GmbH, Duisburg, Germany
dye precursor leuco dyes in a range from 4 to 7.5% by weight.
the formation of the web-like substrate in its execution as paper is done for example on a paper machine, in which at least one upstream Mischbütte a paper pulp of different pulps, optionally groundwood, fillers and water is applied and where preferred to this paper pulp before being fed to the paper machine other ingredients such as resin size for engine sizing and other conventional additives such as pigments, Nuancierfarbstoffe and / or optical brighteners are added.
a paper machine in which at least one upstream Mischbütte a paper pulp of different pulps, optionally groundwood, fillers and water is applied and where preferred to this paper pulp before being fed to the paper machine other ingredients such as resin size for engine sizing and other conventional additives such as pigments, Nuancierfarbstoffe and / or optical brighteners are added.
the first coating composition for forming a CF layer in addition to the zinc salicylate comprises at least one inorganic pigment selected from the list comprising: natural kaolin, calcined kaolin, silica, talc, natural calcium carbonate, precipitated calcium carbonate and aluminum (hydr). oxide.
the CF layer it is possible for the CF layer to contain a pigment mixture, wherein the pigment mixture contains at least one inorganic pigment, more preferably at least two inorganic pigments, selected from the list respectively, comprising: natural kaolin, calcined kaolin, silicic acid, talc , natural Calcium carbonate, precipitated calcium carbonate and aluminum (hydr) oxide.
the CF layer comprises a pigment mixture of exactly two materially different inorganic pigments, each selected from the list, comprising: natural kaolin, calcined kaolin, silicic acid, talc, natural calcium carbonate, precipitated calcium carbonate and aluminum (hydr) oxide ,
the CF layer contains a pigment mixture exclusively of natural kaolin and precipitated calcium carbonate.
the CF layer preferably contains at least a binder selected from the list comprising: styrene-butadiene latex, styrene-acrylate latex, starch, polyvinyl alcohol.
styrene-butadiene latex which is used in particular together with starch.
the zinc salicylate in a range of 4 to 14 wt .-%, most preferably in a range of 5.5 to 11.0 wt .-% - based on the Total weight of the CF layer - integrated in this layer.
Silica, kaolin, aluminum (hydr) oxide and, in particular, natural and also precipitated calcium carbonate may be used as the inorganic pigment within this backside coating, and it is also conceivable to use a mixture of said inorganic pigments with one another or else with other inorganic pigments. If, in addition to the previously disclosed pigments, other pigments are to be used within the backside coating, it is preferred if these other inorganic pigments in a mixing ratio based on wt .-% to silica, aluminum (hydr) oxide or in particular natural or also precipitated calcium carbonate between 1: 4 and 1:25 are included within the second coating composition.
Styrene-acrylate latex, starch, polyvinyl alcohol and very particularly preferably styrene-butadiene latex are suitable as binders within this backside coating.
Wax and / or AKD glue are used in particular as a means of hydrophobing the pigmented coating.
the application of the second coating composition to form a pigmented and preferably hydrophobic coating on the back side of the substrate is preferably accomplished by means of a coater selected from the list comprising: roller coater, curtain coater, doctor blade and doctor blade coater.
the second coating composition used to form this pigmented backside coating is also preferably aqueous.
the subsequent drying of the second coating composition after the application is again usually carried out by a method in which heat is supplied, as is done by hot-air floatation dryer or contact dryer. Proven is also a combination of the listed dry processes.
the areal mass of the pigmented backcoat of the second coating composition is preferably between 2.5 and 4.2 g / m 2, and more preferably between 2.7 and 3.7 g / m 2 .
a paper web of bleached and ground deciduous and softwood pulps with a basis weight of 47 g / m 2 is prepared as standard additives in conventional amounts and in particular with the addition of resin size for engine sizing and at the end of the paper machine as a semi-finished product rolled up on a spool.
a first coating composition to form a CF film and a second curtain coater using a second curtain coater in its slot die design become a second coating composition Formed a pigmented and hydrophobic coating and dried each.
the second coating composition contains as main constituents natural calcium carbonate as pigment, styrene-acrylate latex and starch as binder mixture and AKD glue as a means for hydrophobizing the pigmented backcoat. While the back coating is applied with a basis weight of 3.0 g / m 2 , the basis weight for the CF layer is 4.0 g / m 2 .
the CF layer is alternatively formed from seven different first coating compositions, these coating compositions differing as shown in Table 2 below.
