Definitions
- the present invention relates to the use of combinations containing waxes in photo toners and photo toners containing such combinations.
- photo toners which consist of resins, pigments, charge control agents and waxes and, if appropriate, flow aids, are usually used in modern copying processes.
- the powdery photo toners usually initially image the original to be copied on a transfer roller, are transferred from there to the copy paper and then thermally fixed.
- the waxes contained in the toner as a recipe component promote the release of the photo toner from the fixing roller as a release and anti-offset agent, act as an adhesion promoter during the transfer to the paper and contribute to the homogeneous distribution of the pigments during the production of the toner as a dispersion aid.
- JP-A-1 142 560 describes the use of erucasaureamide in liquid toners. Due to its low hardness, Erucaamid is only of limited suitability for use in toners.
- the invention therefore relates to the use of a combination of erucaamide and one or more wax (s) in photo toners.
- the wax is preferably selected from the group of natural or partially synthetic waxes.
- the wax preferably has a needle penetration number of at most 10 mm "1 .
- the wax preferably has a melting point of 50 to 160 ° C.
- the invention also relates to photo toners containing a combination of erucaamide and one or more waxes.
- the wax is preferably selected from the group of natural or partially synthetic waxes.
- the wax preferably has a needle penetration number of at most 10 mm "1 .
- the wax preferably has a melting point of 50 to 160 ° C.
- the term "wax" is used here according to a definition by the Germans
- Plant waxes such as carnauba or candellila wax or waxes of animal origin such as shellac wax, for example, are suitable as natural waxes.
- Suitable partially synthetic waxes are, for example, bleached montan waxes, which may have been modified chemically, for example by esterification and / or by partial saponification.
- Corresponding products are, for example, in Ullmann's Encyclopedia of Industrial Chemistry, 5th edition, Vol. A 28, Weinheim 1996 in . Sections 2.2, 2.3 and 3.1-3.5 are described.
- Non-polar polyolefin waxes can be produced by thermal degradation of branched or unbranched polyolefin plastics or by direct polymerization of olefins.
- Possible polymerization processes are, for example, radical processes, the olefins, as a rule ethylene, being converted to more or less branched waxes at high pressures and temperatures;
- processes in which ethylene and / or higher 1-olefins are polymerized with the aid of organometallic catalysts, for example Ziegler-Natta or metallocene catalysts, to give unbranched or branched waxes.
- Polar polyolefin waxes are created by appropriate modification of non-polar waxes, e.g. by oxidation with air or by grafting on polar olefin monomers, for example ⁇ , ⁇ -unsaturated carboxylic acids and / or their derivatives, for example acrylic acid or maleic anhydride.
- polar polyolefin waxes can be produced by copolymerizing ethylene with polar comonomers, for example vinyl acetate or acrylic acid; further by oxidative degradation of high molecular weight, non-waxy ethylene homo- and copolymers. Corresponding examples can be found, for example, in Ullmann's Encyclopedia of Industrial Chemistry, 5th edition, vol. A 28, Weinheim 1996, chap. 6.1.5.
- the waxes used according to the invention have needle penetration numbers of at most 10 mm “1 , preferably of at most 5 mm " 1 , furthermore dropping points from 50 to 160 ° C., preferably from 60 to 120 ° C., particularly preferably from 70 to 90 ° C.
- photo toners generally contain resins based on polyester or styrene-acrylate copolymers.
- charge control agents which support the transfer of the toner from the photo roller to the paper base, e.g. quaternary ammonium salts are used for a positive charge and, for example, aluminum-azo complexes for a negative charge of the toner powder.
- quaternary ammonium salts are used for a positive charge and, for example, aluminum-azo complexes for a negative charge of the toner powder.
- small amounts of highly disperse silicas can be added to the toner powder.
- suitable black or color pigments are added to the toners in the thermoplastic mixture.
- styrene-acrylate resin type CPR 100, manufacturer Mitsui; glass transition temperature 60 ° C; MFR 140 ° C 5 g / 10 min
- a black pigment carbon black average particle size of 2 ⁇ m; manufacturer: Timcal
- a charge control agent ®Copy Charge N4S, manufacturer: Clariant GmbH
- 4 parts by weight of an erucaamide / wax combination from Table 1 used according to the invention homogeneously mixed in a kneader , This mixture was then ground to a toner powder with an average particle size of 12 ⁇ m (100% ⁇ 20 ⁇ m).
- silica-based flow agent type HDK, manufacturer: Wacker
- toner powder was now applied to a surface of 20x100 mm.
- This image was then fixed with a roller arrangement consisting of a rigid heatable roller and an elastic cold roller at 160 ° C. and a throughput speed of 150 mm / s.
- Another white sheet was then passed through the hot roller pair and examined for toner residues. No "ghost pictures" could be recognized on the white sheet.
