Definitions
- the present invention relates to a paper coated on one side, a process for its production and its use.
- DE-B-1233248 describes a casting process in which a coating composition containing a metallic pigment and organic binder is applied to e.g. a paper web is applied and dried in contact with a heated high-gloss cylinder.
- a paper with a layer produced by the coating process is used for this purpose.
- the layer consists of a Normal temperature non-film-forming synthetic resin binder, the particles of which have a melting point between 71 ° and 99 ° C.
- the layer can also be applied to a base layer which, in addition to filler, contains one of the customary synthetic resin binders.
- Part of the synthetic resin binder to be used in the base layer can also be replaced by natural binders, so that 10 to 30% by weight of the total binder portion of the base layer consists of, for example, starch, modified starch, methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose and similar substances.
- the so-called “direct method”, as described above for DE-B-1233248, is specified and also the “indirect method”, in which the coating composition is applied to the high-gloss cylinder and the dry one before it is dried Paper is brought into contact with the still wet film, which is absorbed by the paper and pulled off the drum.
- DE-B-2310891 is not the casting process known from DE-A-1233248 (also called the direct method). Rather, here at the same time
- Coating polymer contained initially evaporated part of the water and the film formed at a temperature above 100 ° C under a minimum pressure of 5 kp / cm 2 against a high gloss cylinder.
- an anti-sticking agent can be added to the coating composition. For example,
- Sodium carboxymethyl cellulose, methyl cellulose, polyvinyl alcohol and polyvinyl pyrrolidone in amounts up to 10% based on the weight of the main polymer.
- the usual pre-coatings known from paper manufacture, with and without pigment addition, are provided as the base layer.
- a metallized paper is known from EP-B-98368, in which the layer intended for metallization is formed under similar process conditions as specified for DE-B-2310891.
- the coating composition contains 5 to 25 parts by weight of film-forming binder, based on 100 parts by weight of pigment, and thus has the pigment / binder ratio of the usual paper coatings.
- This proposal is intended to overcome the disadvantage which hitherto existed, which consisted in the fact that the coating surface intended for the metallization first had to be provided with a pre-coating based on organic solvents.
- the proposal according to EP-B-98368 is not free from disadvantages either, because the coating to be metallized must be in a minimum amount of 10 g / m 2 , preferably with an order weight of 18 to 26
- the object of the present invention is now to make available a paper provided on one side with a coating using inexpensive coating raw materials, which due to its high gloss and smoothness should be used where a decorative impression is desired.
- the invention sees a special task in the formation of a cover layer which enables direct metallization of the paper, i.e. Permitted without pre-varnishing with a varnish based on organic solvents, so that a paper of the highest smoothness with high gloss and metallic appearance results.
- the invention also intends to provide a paper which, despite the action of water, has a high gloss retention and is therefore - even in the non-metallized state - suitable for the production of labels which are bonded with adhesives on an aqueous basis.
- the paper In the metallized state, the paper should be able to be printed using gravure and offset printing, in the non-metallized state using gravure and flexographic printing, and - at least with special inks - in offset printing and should have good ink adhesion with mechanical action on the printed surface even in the presence of water.
- the present invention provides paper coated on one side, comprising: a) a cover layer applied by means of a cast coating process, b) formed from a composition consisting of
- the composition for forming the top layer additionally contains up to 5% by weight of mineral pigment.
- Information on the binder content relates to dry weight fractions
- Information on the pigment content relates to the total binder content (dry weight fractions) of the respective composition.
- the invention also encompasses a method for producing a one-sided coated, high-gloss paper with high smoothness, which can be directly metallized.
- a raw paper one-sided
- Coated composition which consists of film-forming synthetic resin binder and / or natural binder and mineral pigment.
- the dried layer is then satinized.
- a second composition is applied to this coating by means of one of the coating devices known per se, which - calculated as dry weight parts - from a natural binder in an amount of 20 to 60% by weight, based on the
- the applied coating is leveled and immediately afterwards fed to a heated high-gloss cylinder and dried in contact with it, the cover layer forming a less porous, closed film layer.
- the process can also be carried out by adding mineral pigment in an amount of up to 5% by weight to the second composition.
- a top layer of higher opacity is thereby achieved, which, however, may be purchased with a lower surface gloss and a reduced surface smoothness.
- a procedure without the addition of mineral pigment in the production of the top layer is therefore particularly preferred.
- a paper according to the invention is preferably used as a support for a vapor-deposited metal layer, in particular for the production of labels with aqueous Adhesives are processed such as bottle labels. Further possible uses are given by the use of the non-metallized paper, also as a label to be processed with aqueous adhesives or as decorative paper, metallized or non-metallized, for example as wrapping paper for gifts.
- the film-forming synthetic resin binders to be used to form the top layer have film-forming temperatures of ⁇ 40 ° C., preferably even ⁇ 30 c, and are used in the form of aqueous dispersions, preferably based on the polymers and copolymers of acrylic acid esters, methacrylic acid esters, butadiene-styrene, vinyl acetate and vinylidene chloride.
- the same film-forming synthetic resin binders are preferably used for the production of the layers forming the coating, however synthetic resin binders with a higher film-forming temperature may also be used here.
- Cellulose derivatives such as are used as natural binders for the production of the coating and the top layer Carboxymethyl cellulose, hydroxyethyl cellulose, preferably casein and starch, modified starch and mixtures of the above-mentioned natural binders.
- Binder preferably at not more than 70 wt.%, Very particularly preferably in a range between 10 and 50 wt.%, Each calculated as
- Dry weight fractions based on the pigment fraction, is 10 to 20% by weight. Titanium dioxide can preferably be used as the mineral pigment for the top layer to improve the opacity of the paper. Better results in terms of
- Addition is dispensed with, especially if one
- the cover layer is transparent and consists only of natural binder, synthetic resin binder and
- Production of the cover layer can be present, such as
- the amount of Total release agents and thickening aids are not more than 10% by weight, based on the total binder content in the top layer.
- a crosslinking aid (wet strength agent) can be present in the top layer.
- the paper according to the invention can be produced particularly inexpensively; the proportion of natural binder can preferably be 32 to 45% by weight. With more than 60% by weight of natural binder, the disadvantage arises that the coating composition has too little solids and the economy is questioned by the high drying effort required. There is also a risk that the water sensitivity of the deck will become thicker and the gloss will decrease.
- the Bekk smoothness of the coating is at least 150 s.
- the air permeability measured according to Gurley, is preferably the satin paper at max. 9,000 s / 100 ml air.
- the top layer is applied up to a maximum of 10 g / m 2, according to a preferred embodiment in a basis weight of only 3 to 8 g / m 2, preferably up to 6 g / m 2.
- the application of the cover layer with such a low mass per unit area forms a further advantage of the present invention in economic terms.
- the cover layer is preferably formed with a gloss in the range from 88 to 98% (gloss measurement according to Lehmann at an angle of 75 degrees).
- the smoothness of the top layer is so high that it cannot be measured with the usual Bekk method.
- a wet strength agent By adding small amounts of a wet strength agent, preferably in an amount of 2 to 10 wt. This is particularly important if the paper e.g. B. is processed into bottle labels and thereby comes into contact with aqueous adhesives.
- a further improvement of the paper according to the invention is achieved if the water absorption is reduced by means of a preparation made from a wax or paraffin dispersion applied to the back. Such a preparation is preferably applied in a basis weight of 1 to 2.5 g / m 2. Such a preparation allows the Cobb value, with which the water absorption is determined, to be in a range from 7 to 12 g / m 2 during 60
- Paper according to the invention - metallized or non-metallized - is used as a label to be bonded with aqueous adhesives. It has also proven to be advantageous to use, in such a use, a raw paper which has been sized and wet-strengthened and which has a relative wet strength of approximately 20 to 35%. This is particularly advantageous if the paper is used to produce labels that are glued to reusable bottles.
- a base paper In order to improve the opacity of papers according to the invention which are not to be metallized, a base paper has proven to be particularly suitable, to which 2 to 3% by weight of titanium dioxide has been added as a mass addition.
- Paraffin dispersion with a basis weight of 2.5 g / m Paraffin dispersion with a basis weight of 2.5 g / m.
- a layer of the following composition is applied to this base paper to form a coating:
- the composition contains:
- the paper web is passed through a super calender and the coating then has a Bekk smoothness of 865 s.
- Air permeability of the satin paper is
- a composition is then applied to this coating using the cast coating process, which is calculated as dry weight parts and is composed as follows: 25 parts by weight of casein
- This top layer is formed with a
- Example 3 A thin metal layer of high uniformity and with a very high gloss was produced on the cover layer of the paper described in Example 1 by the vacuum evaporation method.
- Example 3 A thin metal layer of high uniformity and with a very high gloss was produced on the cover layer of the paper described in Example 1 by the vacuum evaporation method.
- Forming a coating is provided with two superimposed layers. The following layers are applied with the squeegee:
- binder consisting of: 7 parts by weight of enzymatically degraded starch and 7 parts by weight of a butadiene
- Layer a is applied to the intermediate dried layer a in a surface mass of 10 g / m 2, layer b in a surface mass of 12 g / m 2. After layer b has dried, the paper is satinized in a super calender and then has one Bekk smoothness of 2,300 s.
- composition for forming the top layer is then applied to the coating via cast coating:
- This top layer is applied in one
- the paper web is brought into contact with a heated high-gloss cylinder and the composition
- Example 5 The procedure is as in Example 1, but in contrast to Example 1, the composition for forming the top layer still contains 5% by weight of titanium dioxide, based on the binder content of the top layer composition. The opacity is significantly improved, but the gloss is about 10% less than in Example 1.
- Example 5
- Example 4 The procedure is as in Example 4. Instead of titanium dioxide, however, satin white is used, which causes the casein to harden.
- a gloss measurement carried out following the test described in Example 1 for simulating the conditions during bottle etching (headlock test), showed a loss of gloss of only 1 to 2%.
