Definitions
- the invention relates to a heat-sensitive recording sheet having a substrate, a heat-sensitive recording layer arranged on its front side and containing color formers and color acceptors, and a rear-side coating formed on its rear side.
- a recording sheet of the type specified above is known from DE-C-38 36 660.
- the backside coating can be formed from water-soluble high polymers such as starch, gelatin, styrene maleic anhydride copolymer hydrolyzates or polyvinyl alcohol and from water-insoluble polymers such as latices.
- the polymers can be used alone or as a mixture.
- the known back coating is intended to prevent, when used as a label, undesirable influences from plasticizers which are present on a sheet to be provided with the label.
- a barrier layer consisting of water-soluble polymers and a water-repellent wax or a wax-like compound is provided on the back.
- the desired effect is to avoid harmful influences, especially by plastic sealers.
- the back coating and the associated adhesive layer must be transparent.
- the use of pigments such as. B. are often used to improve the thermal head suitability is excluded, so a complicated sequence of the individual process steps is disadvantageously necessary, since the printing process follows immediately after the production of the coating base paper, which is then followed by the further coating and lamination steps.
- US-A-4,593,298 discloses a backside coating comprising an alkali salt of a styrene maleic acid copolymer and a polymeric Latex.
- the water resistance and the block resistance are to be improved.
- the running properties are to be improved and the tendency of the paper to curl is restricted.
- EP-B-0 171 810 describes a back coating in which the durability of the recorded image is to be improved by using a polyurethane emulsion with an application weight of 1 to 5 g / m 2 by preventing liquids, such as plasticizers, Oil, water and solvent penetrate the color development layer from the back.
- EP-A-0 518 552 describes a heat-sensitive recording material in which the substrate consists either of a thermoplastic film or of a synthetic paper.
- a coating applied on the back consists of at least 20% of a water-soluble polymer, such as. B. polyvinyl alcohol, cellulose ether or starch.
- the back coating also contains water-insoluble polymers, such as. B. copolymers of vinyl acetate-acrylic acid esters, methacrylic acid esters and acrylic acid esters, polyurethane resins, polyvinyl chloride resins and polyvinylidene chloride resins.
- a crosslinking agent can be added to the back coating to improve the water resistance.
- a heat-sensitive recording material described in DE-A-37 20 171 which has a colored fluorescent dye composition in its recording layer, is provided on the back with a barrier layer which essentially consists of water-soluble polymer materials, such as polyvinyl alcohol, various cellulose ethers, starch, gelatin, casein and polyvinylpyrolidone as well as water-dispersed resins, such as. B.
- Polystyrene emulsions can be produced.
- the function of the barrier layer is to protect against harmful materials, such as oils and plasticizers, which can discolor the images developed in the recording layer.
- DE-A-38 06 201 discloses a heat-sensitive recording paper in which the paper support has a layer which contains a cationic styrene / acrylic copolymer in order to avoid the formation of dust and flakes when the paper is calendered or supercalendered.
- a further advantage is a wider contact area with the thermal head during recording, a high recording density excellent point rendering, low fog and low adhesion as well as the avoidance of contamination or discoloration on the heat head.
- the cationic styrene / acrylic copolymer can optionally be applied in conjunction with starch, polyvinyl alcohol, a latex, pigment or dye using a size press or a coating device.
- JP-A-60-2397 the surface sizing of a coating base paper is provided which is heat-sensitive for the production
- a primer - underneath the heat-sensitive recording layer it is proposed to provide a primer - underneath the heat-sensitive recording layer.
- a water-soluble copolymer can also be used in addition to a styrene / methacrylate.
- the object of the present invention is therefore to develop a heat-sensitive recording material with a back coating which has a good barrier action against the substances used in offset and flexographic printing, in particular organic solvents and against plasticizers, oils and greases. Furthermore, the blocking of the web wound on a roll in the roll should be prevented.
- the problem is solved in the case of a heat-sensitive recording sheet with a substrate, a heat-sensitive recording layer arranged on its front side and containing color formers and color acceptors, and a rear side coating formed on its rear side in that the rear side coating is formed from a mixture which
- an acrylate copolymer comprising no styrene or vinyl acetate components and having a film-forming temperature of ⁇ 5 ° C.
- acrylate copolymer used in the description and claims includes an acrylate and / or methacrylate To understand copolymer that does not include styrene or vinyl acetate components and preferably has reactive groups.
- the copolymer to be used according to the invention can be in the form of an aqueous dispersion or emulsion.
- the use of an alkaline catalyst ensures the crosslinking of the acrylate copolymer and counteracts the tendency of the paper web to block.
- starch also means starch derivatives, such as starch ethers and starch esters, in addition to starch itself.
- starch and the acrylate copolymer are cationic.
- a paper consisting mainly of cellulose fibers is preferably used as the substrate, in particular a paper is preferred whose fibrous material consists of wood-free cellulose fibers.
- the excellent barrier effect is probably explained by the film-forming properties of the acrylate copolymer, which forms a relatively soft and slightly sticky film without the addition of starch according to the invention.
- the backside coating be based on it Total weight, contains 40 to 50 parts by weight of starch.
- the back coating based on its total weight, contain 30 to 40 parts by weight of the acrylate copolymer.
- the backside coating contains 9 to 28 parts by weight, very particularly preferably 13 to 24 parts by weight, of the alkaline catalyst.
- Metal carbonates have proven to be suitable alkaline catalysts, in particular calcium carbonate and magnesium carbonate have proven suitable, a precipitated calcium carbonate being very particularly preferred.
- sodium carbonate is unsuitable because the sodium ions can cause corrosion of the thermal head. Potassium and chloride compounds are also unsuitable.
- the back coating can contain a crosslinking aid, in particular an epichlorohydrin resin.
- an application weight of 1 to 3 g / m 2 for the backside coating in particular in the range from 1.5 to 2.5 g / m 2 , has proven to be suitable.
- Back coating is not to be confused with the long-known use of cationic sizing agents, such as those added to the fibrous material for mass sizing or possibly also applied as surface sizing agents by means of a size press or similar devices. These known application methods do not lead to a closed film, as is produced on one side of a paper web with the back coating provided according to the invention.
- the heat-sensitive recording paper according to the invention is used as a label in food packaging and is particularly suitable for labeling labels for frozen foods to be applied with special glues.
- the backside coating according to the invention prevents the penetration of plasticizers into the label in this application, so that there is no discoloration or change in the typeface produced on the front side in the heat-sensitive recording layer.
- the heat-sensitive recording layer is covered with a protective layer
- Another area of application is the production of tickets printed on the back with additional information, but in particular of those tickets which are printed on the back with solvent-containing magnetic strips.
- aqueous preparation consisting of 47 parts by weight of cationic starch, 16 parts by weight of precipitated calcium carbonate and 37 parts by weight of a cationic acrylate copolymer free of styrene or vinyl acetate components was prepared.
- the preparation was adjusted to a solids content of 18% by weight - pH 7.5 - and applied in an amount of 2.2 g / m 2 to a base paper and dried.
- the other side of the coated fabric web was provided with an intermediate layer for receiving the heat-sensitive recording layer, the essential components of which consisted of an oil-absorbing pigment and binder.
- the intermediate layer formed was then provided with a conventional heat-sensitive recording layer.
- a further preparation with an 18% solids content was prepared from the same components, but using 44 parts by weight of cationic starch, 34 parts by weight of an aqueous cationic acrylate polymer and 22 parts by weight of precipitated calcium carbonate.
