Methacrylic acid and 10% vinyl acetate used There will be a solution of 20 kg in polyacrylic acid. The plastic film is dried using a mixture of 40 kg of ethanol and 40 kg of methaine on a dry slope. 5 nol manufactured. This solution is on the back.

Solvent mixture of 61.5 kg of ethyl glycol and a solution of a copolymer of 20.5 kg of tetralin is dissolved.

This 15 acetate and butyl acetate are made. The solution is plastic solution is applied by means of a doctor blade to the rear side of a cambric paper web by means of a doctor blade on the back of a paper web, from which high-gloss ice cream paper is applied. The art for the application of plastic is 12 g / m², based on the material application is 10 g / m², based on the dry and dry substance. The solvent becomes substance. The solvent is evaporated by drying by drying in a drying tunnel. 20 evaporated in the drying tunnel.

A plastic solution made according to Example 2. A solution made from 15 kg of a carboxylated meth has been, with the help of a doctor blade on acrylic acid ester in 35 kg of butyl glycolate and a plastic film made of polyvinyl chloride, which contains a 25 7 kg tetralin, is on the back of a paper thickness of 40μ, applied. Applied to the plastic sheet made of velor paper. The plastic application is 8 g / qm, based on dry matter. order is 15 g / qm, based on dry-Das Solvent is made by drying in the dry substance. The solvent is made by drying channel evaporates. evaporated in a drying tunnel.

Claims (1)

1 2 to dry adhesive papers that already have the adhesive patent claim: wear the order and only need to be re-moistened for gluing. It is obvious that this is Use of if necessary with an addressed technical problem in which the Surface refinement coated paper 5 glue is only applied immediately during the gluing process or from plastic films, which become hydrophilic with, could not obtain any stimulation from papers, Polymers containing carboxy groups, mixed pods, the adhesive layer already as a fixed application lymerisaten or their mixtures contain coated. are, as labels and blanks to stick on As carrier paper for labels prepared in this way Both natural and uncoated papers come on objects by means of glue on aqueous or io and blanks Dispersion base. also all types of coated papers are in question, such as B. chrome, gloss, ice cream, high gloss, Bronze, plastic, cambric and velor paper. Can be used as a carrier for the plastic preparation 15 plastic films instead of paper, ζ. Β. out Used for labeling bottles, cans and polyvinyl chloride, polyamide, cell glass and the like Boxes as well as for covering cardboard boxes. Cases and other utensils are used. B. Polyz. B. Chromo or Cambric paper used, which only acrylic acid, methacrylic acid, maleic acid, crotonic acid at the point of use on their back with and their salts and the like., Proved to be suitable, and the required glue on aqueous or dispersing, although also in the form be provided by copolymers or sion-based. · Polymer mixtures with other carboxyl group-like labels or blanks have the 25-containing vinyl compounds or other compatible disadvantage that they borrowed when the glue was applied. Connections, e.g. B. polyacrylic acid esters, poly-caused by the impact of moisture in the methacrylic acid esters, polyvinyl chloride, polyvinylidene used adhesive, have a strong tendency to roll, so that chloride, polyvinyl acetate, polyvinyl alkyl ether, polycyclic often difficult to stick to the vinyl acetate, styrene, etc. The only condition is that that Have the object applied. Another disadvantage of copolymers or polymer mixtures in water, which is often observed, is that the glue is swellable. The arrangement of the individual layers even penetrates through the paper, so that the drawing shows, in the enlarged top side of the label or the blank, on a larger scale A, a cross-section through a so-called glue stain according to the previously prepared label made of natural paper that make the label or the blank unsightly 35 and B a cross-section through a device according to the invention. It also often happens that the pre-prepared label from a surface glue is repelled from the label paper, so that noble paper is displayed. that there is no uniform application of glue and the 1 and 4 in the drawing denote the carrier labels or blanks bad on the pasted paper, which can be wood-free or wood-containing, 3 den Stick object. 4 ° surface finishing line and 2 or 5 the hydro according to the invention these disadvantages are avoided by preparing a carboxyl-based backside preparation the use of possibly with a, group-containing compound, on which at Ge surface finishing coat provided paper or use the labels or the blanks of the glue of plastic films, which is applied with hydrophilic carboxy. group-containing polymers, copolymers 45 The new labels that come in a wide variety of or their mixtures are coated, as labels shapes, e.g. B. square, rectangular, circular, and blanks for gluing onto objects oval or punched out in irregular areas by means of glue on an aqueous or dispersion basis. have the advantage of being without The use according to the invention of with the roll, with the help of an aqueous adhesive on the named pre-preparation treated labels or 5 ° various objects, eg. B. made of metals, Cutting to size has the advantage that, as a result of the hydro- glass, cardboard, paper, plastics and wood, phile nature of the preparation the glue can be glued over. The entire label surface is assumed to be even. Below are a few examples of how a perfectly perfect bond is obtained. Provision of labels or blanks with backing The particular advantage of the hydrophilic page preparation used is listed,
Polymer preparations containing carboxy groups mainly consist in the fact that the label or its example 1
The cut is still permeable to water vapor and thus After the label has been applied, for example, on 5 kg of polymethacrylic acid, a bottle of 95 l of water can dry quickly, which in particular suspends 60%. Stirring is then continued in the Suspenbei the high operating speed of modern la- sion a 3 1 25 ° / _o aqueous ammonia. The chain devices thus obtained is important. Solution is applied by means of a coating machine through roller-case adhesive papers, as described, for example, in the order on the back of a chromo paper in German patents 603 200, 724 395, the order, based on dry bonding, being known per se as adhesive layer 65 substance, 10 g / qm. After drying the polymers and copolymers to be used, coated film this is for the purpose of curing at a two-layer job very thin layer as intermediate with a 5 ° / _o aqueous solution of. In all of these papers, however, aluminum sulfate is sprayed over, and it is then
