Coated synthetic paper and method for its Manufacturing

The invention relates to a coated synthetic paper having a thickness of more than 15 microns consisting of a Plastic film with a single or double-sided, opaque, printable, pigment-containing coating, which is generally used for almost all common uses Paper can be used and especially for high-performance prints and

309831/0862

graphic purposes is usable. The invention also relates to a method of making such a coated synthetic Paper. The products produced by the process according to the invention have printing properties and a surface strength, which is equal to or often superior to that of conventionally coated cellulose paper. In addition, they have all of the beneficial properties of the plastic carrier film including tensile strength and dimensional accuracy.

Many attempts have been made to use polymeric films as replacements for paper products. There are many good ones for that Reasons.

Polymeric films have good tensile properties and are both chemically and dimensionally stable. Unfortunately, however, it causes great difficulty in making them accept a printed image and, being essentially transparent, are such printed images are clearly visible.

Attempts have been made to improve the printability of plastic films and the transparency of the printed image Coating the film with various coatings, as is often the case

309831/0862

used to improve the quality of paper. These coatings are usually available as an aqueous suspension put together, which is applied to the paper and dried.

In contrast to paper, which is made from cellulose fibers, Not only do plastic films lack water and air permeability, they are also highly water-repellent. That's why The films prove to be unsatisfactory when used with conventional aqueous coating compositions for a variety of reasons be coated. In particular, they are unsuitable for writing on and printing on, e.g. for high-performance printing.

There are products known by coating a soft or roughened surface of a plastic film with an organic solvent coating mixture, which are a pigment, such as kaolin, calcium carbonate, talc, titanium dioxide and the like and contains a synthetic binder or adhesive resin which may be of a polyvinyl or polyester type.

U.S. Patent 2,955,970 discloses the manufacture of a product on, which is described as synthetic paper that is produced by

3098 31/0862

Coating an activated polyethylene film with an aqueous coating material which is 100 parts of a Pigment and 5 to 25 parts of a starch synthetic rubber adhesive contains.

When preparing such products, inevitably, many technical manufacturing problems have to be solved in order to produce products with to maintain the desired properties of coated paper, such as surface adhesion and printability. Of the The last term includes properties such as the ability to absorb ink, printing inks, gloss and drying speed a. Usually attempts are made to improve one property while deteriorating another. For example, increasing the amount of binder to improve surface adhesion often causes a decrease in absorbency for ink or printing ink. In addition, the surface of the Product usually be soft and attractive and not subject to cracking or chipping. The result are still no completely satisfactory products have been achieved.

One of the main materials used in the production of coated plastic films that can be used as a replacement for cellulose paper

309831/0862

The difficulty is that the moisture of the coating composition cannot evaporate through the carrier material. Evaporation is limited so that it only takes place in the direction of the surface exposed to the atmosphere. This is in contrast to conventional paper, where the moisture escapes in both directions. For this reason it is essential during the drying process that the coated film can dry at low temperatures while constantly maintaining a balance between the moisture content of the layers on the surface and the interior. When the coated film is dried at low temperatures for an extended period of time ₇ , bald spots often appear on the surface of the coating. As a result, the coating is rough and uneven and has poor appearance. Bald spots are tiny, uncoated areas that are caused by the partial rejection of the aqueous coating by the carrier material and also by the contraction of the layer during prolonged drying. In addition, lengthy drying processes are not economical.

On the other hand, fast drying often causes cracks in the coating due to the differential shrinkage,

309831/0862

which is due to the steep drying speed gradient along the thickness of the coating. This cannot be remedied by using a more viscous coating with a higher solids content. The reason is that difficulties arise in the extent that the coating composition becomes more viscous with respect to a uniform coating to achieve softness and smoothness.

The problem of flaking can be alleviated even under more stringent drying conditions by increasing the proportion of binder to pigment. However, this procedure is unsatisfactory because the binder tends to migrate to the surface of the coating during the drying process, with the result that the binder is unevenly distributed along the depth of the layer. The migration of the binder strengthens the surface of the layer, but has a negative effect on the absorption and drying of printing ink and ultimately causes the product to block. This last disadvantage robs any possibility of using the products in modern high-performance printing.

With modern printing techniques, especially offset printing, it is necessary to use high-viscosity printing ink to achieve sharp images

309831/0862

to use. The main difficulty with synthetic paper that has hitherto been made from plastic films, consists in that the top coating of the synthetic paper in the tests to print them with printing ink of adhesive number 12 or higher, comes off or peeled off and on the surface of the printing plate or the blanket gets stuck. Attempts to reduce this problem by To master the viscosity of the printing ink, have a reduced capacity for the printing ink and thus a Transfer of the image performed.

Despite the need for a synthetic paper, especially in those countries that have little or no sources of pulp, and despite repeated efforts in research, no satisfactory substitute for paper has yet been made, which would be useful for high performance printing and graphic purposes.

While there is already a method of making one that is coated synthetic paper has been proposed, in which the loading

layers of a plastic film with an aqueous coating mixture takes place that for every 100 pigments 5 to 30 solid parts

309831/0862

of a latex binder, 0.15 to 3 parts of a heat sensitive one Coaguliemmittels and 0.75 to 4.5 parts of a nonionic> Wetting agent and, if desired, 2 to 20 parts satin white and in which the paper is dried at an elevated temperature at which the film does not soften.

However, this method also has certain disadvantages in some cases.

In the above-mentioned single-layer coating method, FIG coated film has some uneven coating areas compared to conventional paper. To avoid this disadvantage, you should the coating weight should be limited to approximately 20 grams per square meter.

In other respects, except when an opaque film provided with a special filler is used as the support or a special coating composition that uses a pigment with a higher refractive index, such as titanium dioxide, it is inevitable that the opacity of the coated Films always lower than that of conventional coated paper when using products with the same coating weight compares with each other.

309831/0862

For the above reasons it is beneficial to have a coated product free of uneven coating areas and with a high degree of opacity

did to get a coating with more than 20 grams per m to be applied by means of a multilayer coating process.

The mere coating in several layers without consideration the surface property of the layer to be coated, however, would only lead to the formation of a number of finely drawn craters, similar to a lunar landscape, run on the coated surface of the top layer, with the result that such uneven Layers cannot be used for high-performance printing.

The object of the invention is therefore to remedy the aforementioned disadvantages.

A coated synthetic is used to solve this problem Paper consisting of a plastic film and a coating on one or both sides proposed, which is characterized in that that the coating is 15 to 40 g / m 2 and consists of two layers, of which the top layer has a small proportion of binder, i.e. 10 to 26 parts per 100 parts of pigment, and the base coat contains a larger proportion of binder, i.e. 28 to 100 parts

309831/0862

- ίο -

has, wherein the proportion of binder during drying on the surface of the base layer can be greater than in the interior that the binder migrates to the surface of the top layer. A method for producing a coated synthetic paper is also proposed, which is characterized in that a plastic film is coated on one or both sides with a viscosity of about 50 to 1000 cps, the mixture per 100 parts of pigment, about 28 to 100 parts by solid of a latex binder and about 0.2 to 0.7 parts of a dispersant and, if desired, 2 to 20 parts of satin white, and that the coated plastic film is at a temperature of about 70 ° C to a temperature of about 50 ° C above the softening point of the Plastic film is dried, whereby the base layer is formed on the film, and that is then coated again with an aqueous coating agent having a viscosity of about 50 to 100 ocps, the mixture per 100 parts of pigment, about 10 to 26 parts solids content of a latex binder, about 0.2 to 0.7 parts of a dispersant and, if desired, 2 up to 20 parts white and / or 0.5 to 3.9 parts of a nonionic wetting agent as a protective agent and 0.1 to 2.6 of a heat-sensitive one

309831/086 2

Has coagulant that works at room temperature or a relative low temperature has no effect on the coating mixture, but the coating mixture remains at an elevated temperature brings about coagulation.

The plastic films which can be used in the method according to the invention for the production of the novel product are generally all such thermoplastics that are formed into films and can be coated by the treatment described in more detail below. They include, for example, polyvinyl plastics, in particular polyvinyl chlorides and copolymers of vinyl chloride with vinyl ester, such as vinyl acetate, and with vinylidene components, in particular vinylidene chloride. They also include styrene-based polyvinyl polymers and various known ones Copolymers thereof. Polyolefins, particularly polyethylene and polypropylene, can also be used. further explanation can be made exemplary; Films are made from polyamides, polyesters, polyurethanes, natural and man-made Rubber, polycarbonates, cellulose derivatives, such as cellulose di or triacetate. The films can be plasticized

2263Λ5Λ

or remain unplasticized. You can mono- or biaxial or not oriented. Each of these films can, when treated according to the method of the invention, in the useful products described therein and thus claimed are transferred. Of the numerous products available as a result of the invention, those based on Polystyrene, polyvinyl chloride and polyethylene are preferred because the starting materials are readily available at a reasonable price and because the properties are particularly beneficial for one Own number of uses.

As a pigment useful in the invention, any or any one can be used pigment commonly used in the coating of ordinary paper for the production of printable surfaces. This includes, for example, kaolin and other types of clay, calcium carbonate, talc, titanium dioxide and the like «

However, the pigments to be used for the preparation of a base layer should not be such as diatomaceous earth, calcium carbonate and some kinds of alumina or the like. be. It has been shown that in the case of a base layer using coating agents with such pigments as diatomaceous earth, calcium carbonate and some

309831/0862

Types of clay or the like. no satisfactory top layer towards it is because numerous craters are formed on the surface layer.

The latex binders useful in the invention belong to known latex binders and are for example: various acrylic polymers, modified styrene-butadiene rubber, modified Methyl methacrylate-butadiene rubber, styrene-methyl methacrylate-butadiene rubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate copolymers and like polymers and copolymers.

Up to 10 % of the latex binder in each layer can be replaced with a water-soluble polymeric binder. In preferred variations, about 7-10 % of the binder is comprised of a water-soluble polymeric binder, such as casein, starch, modified starch, polyvinyl alcohols, and the like.

In the event that the greater amount of latex binder is used as the sole binder or in conjunction with a water-soluble polymeric binder in an amount of from about 7 to 10 % of the binder contained in the coating mixture

309831/0862

the surface adhesive strength of the synthetic paper coated in this way increases according to the amount of binder used, whereby a soft and even surface is obtained.

However, the binders migrate to the surface of the coating during drying, resulting in an uneven distribution of the binder leads in the layer and the absorption capacity and drying capacity for printing ink is reduced.

Nevertheless, the migration of the fertilizer in the base layer is reduced not the ability to absorb and dry printing ink, because the top layer overlays the base layer and all possible adverse effects of the base layer in terms of absorbency and drying ability for Could result from printing ink, extinguishes.

The relationship between the pigment to binder ratio in the base coat and the properties of the coated synthetic Paper are shown in the table below.

As the table above shows, the binder content, in order to meet the required conditions for the coated product, in the base layer greater than 28 parts per 100 Parts be pigment. However, when the binder content exceeds 100 parts, a tendency to block becomes so noticeable that that part of the layer formed on the substrate tends to be detached from the guide rollers of a coating machine

3 098 3 17 0862

2 2 6 3 4 5 Λ

to become. Thus, the binder content in the make coat should be between 28 to 100 parts.

On the other hand, the binder content should be in the top layer between 10 to 20 parts per 100 parts of pigment for the case that no heat-sensitive coagulants, as below described, be used. If used, they should be between 10 and 26 parts, if for education If the binder is used for the outer layer below the above-mentioned limits, no satisfactory surface adhesive strength is obtained. However, good ink receptivity cannot be achieved if the binder content is above upper limit is.

Heat-sensitive coagulants which are suitable for completing the process steps according to the invention can be: a salt or mixture of salts of divalent lead, zinc, magnesium, calcium, strontium or barium, or trivalent chromium or aluminum in conjunction with a constituent of the group Sulfate, phosphate, nitrate, isothionate and halogen ions; Polyvinyl

The polyvalent metal salts are not limited to individual salts from cations and anan, but also include them Complex and double salts.

These heat-sensitive coagulants dissolve when they are in the Coating mixture are used or are present, a coagulation process during heating, causing migration prevents the binder and increases the printability and anti-blocking tendency of the coated surface.

Furthermore, the retention of up to 26 parts by weight of binder to pigment in the layer to be applied is also possible, which allows a noticeable increase in surface strength.

309831/0862

It should be noted that the heat sensitive coagulants cannot be used in the coating mix for the basecoat. The reason is that their reluctance to Preventing cfer binder migration leads and consequently the occurrence increased by craters on the top layer and the pressure effects are impaired.

The heat sensitive coagulants are used in an amount of about 0.1 to 2.6 parts per 100 parts of pigment.

The reason is that there is no benefit in using less than 0.1 part of coagulant. However, the other hand occurs if significantly more than 2.6 parts of coagulant are used, premature coagulation occurs.

The heat-sensitive coagulant is used in conjunction with a applied nonionic wetting agent, which serves here as a protective agent. Examples of suitable wetting agents are: ethylene oxide, Addition products of higher alcohols, alkylphenol, fatty acids, polyhydroalcohol fatty acid esters, higher alkylamines, fatty acid amides, fatty oils and polypropylene glycol. A few simple ones

309831/0862

Observation readily suggests the usefulness and effective amount of a particular nonionic wetting agent in making products according to the method of the invention. It has been generally observed and found that the effective amount between 5 O ₇ on 100 parts of pigment and 3.9 parts.

When preparing the mixture in which heat-sensitive coagulants and protective agents are used, the two are mixed together and then added to the coating mixture ₇ before the heat-sensitive coagulant is used. In the other case, the viscosity of the mixture increases greatly so that the procedure is difficult.

A dispersant or mixtures of dispersants become used in the preparation of the mixtures according to the invention. A content of 0.2 to 0.7 parts in the mixtures is typical to 100 parts of pigment. Phosphates are most beneficial, although others are also used with less desirable results can be. The use of alkali metal phosphates, such as sodium phosphate, pystphosphate, metaphosphate, hexametaphosphate and Tripolyphosphate is explained further using an example.

Satin white is a calcium sulfo-aluminate and is made by the following Formula reproduced:

3CaO * Al ₀ O ₀ ^# 3CaSO. * 31H ₀ O

It is made by the reaction of slaked lime and aluminum sulfate. It is because of its good restraint of water particularly useful. It is also used to prevent the. Formation of cracks, advantageous even under severe drying conditions. Under suitable conditions, the products can be used according to of the invention can be produced by using satin white in a surface layer which is free from the heat-sensitive Is a coagulant or protective agent. Normally the proportion of satin white used in the products according to the invention is in the range On the order of 2 to 20 parts per 100 parts of pigment.

The coating mixture according to the proposal of the invention can in addition to the specific agents listed above, dyes, coloring liquids ,. Contain antistatic agents and other conventional ingredients used in the paper coating art.

309831/0862

The used films can be coated in the same way as conventional paper, being one of the conventional Coating equipment is used, such as a roller doctor blade, an air knife or a coating with an air knife. The preferred one Coating method depends in some way on the viscosity of the mixture to be applied, which is normally between about 50 to 1000 cps. varies when using, for example a Brookfield Synchroelectric Viscometer. The total coating weight in the dry state is between approximately

2 ■ 2

15 to 40 g / m. (in this case 10 to 25 g / m, while 5 to

15 g / m dry weight advantageous for the top and base layers are.)

After the wet coating process is complete, each is separated Layer dried to evaporate the water, and a soft, flat, opaque and printable. To produce surface. Conventional drying equipment can be used, e.g. Festoon dryer, tunnel or cylinder dryer.

In a drying process, the entire procedure is carried out under more severe conditions, which at such low temperatures

309831/0862

rotations as high as 70 C to as high as 50 C above the softening point of the plastic film for a period of approximately 10 seconds to about 2 minutes are enough. In general * drawn, the temperature below the softening point of the Keep it fine, i.e. about 15 C below the softening point. The preferred period of time for performing this process is between 10 and 40 seconds.

Another method that is preferred for products that have lower proportions and even free of heat-sensitive ones Are coagulants and protective agents, consists in the initial drying under more stringent conditions, as described above, run until the viscosity of the layer is approximately 1800 to 2000 cps. reached, and then to continue drying at a temperature of about 20 C to 60 C until the layer has reached the desired degree of dryness, i.e. for about 3 to 10 minutes.

The optimal drying conditions vary with the type of coating process or with the number of layers or bits the type of coating mixture.

309831/0862

In general, however, the first method will be for coating mix the base layer can be selected. The reason is that immediately after the formation of the base layer, it dries quickly can be, whereby the binder migrates, whereby the base layer is rich in peeling agent on the surface. the first method delivers products that are soft, even and free from bare spots and craters have sufficient adhesive strength to withstand ordinary writing and printing. The adhesive strength of products made by the second method usually turns out to be better out. Alternatively, the adhesive strength can be improved by calendering, and this process has the additional property of to improve the print quality of the opaque film far more.

The detailed explanation on the previous pages was made on a coated plastic paper with a plastic film, which is covered on one or both sides with an opaque, printable, pigment-containing coating was coated from two layers, referred to. The use of the coating material forming the base layer according to the proposal of the invention ds an intermediate
