Definitions
- the invention relates to a first sheet for carbonless copy sets made from pressure-sensitive carbonless paper according to the preamble of claim 1.
- Such first sheets which are also known under the name OB sheet (coated back), are known.
- OB sheet coated back
- the capsule-coated back of the first sheet is also printed, the printed image is visible through the thin paper. and disturbs the visual impression of the top.
- a carbon copy rate usually consists of a first sheet (CB), one or more middle sheets (CFB) and a final sheet (CF).
- CB first sheet
- CFB middle sheets
- CF final sheet
- the adhesive adhesion for the purpose of functional removal of one set of the block between the CF underside and the CB top is to be lower than between the CB underside and the CFB top or the CFB underside and the CF top. If not: top coated.
- the first page was solved by setting, surface preparation and regulation of the absorbency of the corresponding backsides. However, these measures failed with the first sheets coated with pigments on the top.
- EP-A-0 274 886 already proposed to additionally provide the coated top side with a synthetic, reactive sizing agent or with a line structure agent or with both agents in order to ensure self-release gluing.
- a disadvantage of this proposal is that synthetic, reactive sizing agents have a certain dwell time for complete reaction Temperature range above 100 ° C. If this is not the case, e.g. B. if the coating unit is driven too quickly or if the drying capacity of the coating unit is a bottleneck, the synthetic sizing agent does not harden - with the result that the degree of glue or hydrophobization required for the self-separating gluing of the CB sheet provided with a printable top line does not is achieved.
- the object is achieved in a first sheet according to the preamble of claim 1 in that the top coating contains non-reactive hydrophobizing agents in a proportion of 5 to 15% by weight, based on the dry content of the coating.
- Non-reactive water repellents such as wax glues
- Wax emulsions metal salts of fatty acids, such as. B.
- Copolymer dispersions and dispersions from organic prepoly eren are known per se and were in the
- Wax glues as well as metal and ammonium salts of fatty acids, especially stearic acid, are also occasionally used in coating colors for printing papers in order to improve the internal sliding behavior of the coating pigments when calendering, the printing ink level during the printing process and the so-called dust behavior.
- the amount used in the coating color was limited to 0.3 to 1.2% by weight dry, based on the dry content of the coating color.
- EP-A-0 274 886 also makes use of this knowledge by specifying on page 5, lines 42 to 43 lubricants, in particular queurite stearates, as a further coating color additive, the proportion according to Examples 2 to 6 and 8 each being 0.5% by weight % should be. This document does not suggest an improvement in the self-separation behavior through the addition of
- first sheets for carbonless copy sets made of pressure-sensitive carbonless paper with excellent top side printability and printability and good self-separation behavior can be provided if the proportion of non-reactive hydrophobizing agent in the top coat layer between 5 and 15% by weight, based on the dry content of the coating, is selected.
- the proportion of non-reactive hydrophobizing agent in the top coat layer between 5 and 15% by weight, based on the dry content of the coating, is selected.
- Hydrophobing agents are understood to mean additives to the coating color for the top coat layer which, after the application of the coating color and the subsequent drying, have no further components, such as, for. B. hardener or crosslinker, and do not need a high temperature and residence time for reaction with OH groups and for the formation of the hydrophobicity effect.
- the Ca or Na salt of a fatty acid such as. B. stearic acid
- the ammonium salt of stearic acid has proven itself, but it should be noted that the viscosity of the coating color produced therewith increases with higher proportions, so that the person skilled in the art must select the coating units then required for applying the coating from the doctor or rod metering devices.
- a further useful hydrophobizing agent is a mixture of glossy ester waxes and low molecular weight, oxidized polyethylene. Such blends are e.g. B. as aqueous dispersions with a solids content of 30 wt.%, An average particle size of 0.2 microns and a pH of 8.5 to 9.0 in the trade and are sold under the trade name "Wükonil PW”.
- Another useful, non-reactive hydrophobizing agent is the so-called montan wax glue made from montan wax, especially in its bleached form. Further information on montan wax glue is given in the reference "Wochenblatt für Textilfabrikation 82 (1954), page 623.
- non-reactive hydrophobizing agent is available in the form of an aqueous dispersion of an organic prepolymer, as described in the technical data sheet from Schill & Seilacher under the product name "ÜKASOL NL". According to the invention, these water repellents can be used individually or in a mixture with one another.
- All pigments known in paper coating technology such as kaolin, calcined kaolin, ground or precipitated calcium carbonate, talcum, individually or in admixture with a conventional binder, such as, for example, can be used as natural pigments for the top coating.
- a conventional binder such as, for example
- B. styrene butadiene latex can be used. The person skilled in the art has no limits here, he will select the pigments based on the requirements for whiteness, gloss and the required smoothness of the top coating of the first sheet.
- the proportion of these natural pigments in the total proportion of the pigment mixture can in itself be selected as desired, but is preferably 70 to 90 parts by weight, based on
- the top coating also contains synthetic pigments such as precipitated silica, titanium dioxide or finely divided aluminum hydroxide in addition to the natural pigments individually or in mixtures.
- synthetic pigments such as precipitated silica, titanium dioxide or finely divided aluminum hydroxide in addition to the natural pigments individually or in mixtures. The selection is based on the requirements of printability and printability as well as the desired final whiteness of the coating. If high opacity is to be achieved, titanium dioxide is indicated as pigment. If special requirements are placed on the oil adsorption of the printing ink, the addition of precipitated silica is recommended.
- the proportion of synthetic pigments is preferably 10 to 30 parts by weight, based on 100 parts by weight of the total pigment mixture dry.
- the specialist is free to choose the weight of the top coating. It has been shown that in such
- the application weight is too high (over 12 g / m), the carbonless properties of the first sheet will deteriorate. It has therefore proven to be advantageous to select the application weight between 4 and 10 g / m 2. A is particularly preferred
- the formulations according to Examples I to IV were based on a base paper of 48 q m 2 basis weight in a quantity of 6 g / m 2, which was wood-free in the mass and was sized in the size press and provided with a preparation of starch in the size press, for the production of pressure-sensitive carbonless papers. calculated as dry matter - applied. After applying the top coat, drying and Satinage was then applied to the back of the actual capsule line and also dried.
