Definitions
- the present invention relates to the use of waxy, aromatic Unit containing compounds in photo toners and photo toners, such Contain connections.
- photo toners used consisting of resins, pigments, charge control agents and waxes as well optionally flow aids exist.
- Form the powdery photo toners When copying the template to be copied usually first on one Transfer roller from, are transferred from there to the copy paper and subsequently thermally fixed.
- the waxes contained in the toner as a formulation component favor as Separation and anti-offset means the detachment of the photo toner from the fixing roller, act as a bonding agent in the transfer to the paper and contribute to the Preparation of the toner as a dispersing aid for the homogeneous distribution of Pigments.
- wax components in photo toners are so far predominantly Hydrocarbon waxes such as polyethylene or polypropylene waxes used. These waxes meet the requirements of modern fast-moving Copy machines do not do justice in all aspects.
- EP 0 291 872 A1 discloses waxy esters of aromatic alcohols and their Use as lubricant for highly transparent thermoplastic materials described.
- the invention accordingly provides for the use of waxy compounds of the formula (I) in photo toners, wherein R 1 is the group -CH 2 -O-CO-R 3 or -CH (OH) -CH 2 -O-CO-R 3 , R 2 is an alkyl radical having 1 to 4 C atoms or halogen, R 3 is an unbranched alkyl radical having 16 to 36 carbon atoms and m is 1, 2 or 3 and n is 0 to (6-m).
- R 1 is preferably the group -CH 2 -O-CO-R 3
- R 2 is an alkyl radical having 1 to 4 C atoms or halogen
- R 3 is an unbranched alkyl radical having 16 to 36 carbon atoms and m is 1, 2 or 3 and n is 0 to (6-m).
- the invention furthermore relates to photo toners containing at least one Pigment component, a resin component and a waxy, aromatic Unit-containing component of the formula (I).
- wax-like compounds of the formula (I) which can be used according to the invention are formed by reacting aromatic compounds of the formula (II) or of the formula (III) with carboxylic acids of the formula (IV) R 3 -COOH
- R 1 is the group -CH2-O-CO-R 3 or -CH (OH) -CH 2 -O-CO-R 3
- R 2 is an alkyl radical having 1 to 4 C atoms or halogen, preferably an alkyl radical having 1 to 2 C atoms or chlorine
- R 3 is an unbranched alkyl radical having 16 to 36 C atoms, preferably having 26 to 32 C atoms
- R 4 is the group -CH 2 OH or -CH (OH) -CH 2 -OH, preferably -CH 2 OH
- R 5 is the group such as m is 1, 2 or 3, preferably 1 or 2, and n 0 to (6-m), preferably 0 to 3.
- Suitable starting compounds of the formula (II) are, for example Benzyl alcohol, o-, m-, p-tolylcarbinol, chlorobenzyl alcohol, bromobenzyl alcohol, 2,4-dimethylbenzyl alcohol, 3,5-dimethylbenzyl alcohol, 3,4,5-trimethylbenzyl alcohol, p-cumene alcohol, 1,2-phthalyl alcohol, 1,3-bis (hydroxymethyl) benzene, 1,4-bis (hydroxy-methyl) benzene.
- a suitable starting compound of the formula (III) is, for example, styrene oxide.
- Suitable carboxylic acids of the formula (IV) are, for example, arachic acid, behenic acid, tetracosanic acid, cerotic acid, montanic acid, melissic acid, in particular technical montanic acid, which is essentially a mixture of C 18 -C 36 -carboxylic acids with a predominant proportion of C 26 -C 32 -carboxylic acids and is obtained by oxidative bleaching of raw montan wax (see, for example, Ullmann's Encyclopedia of Industrial Chemistry, 5th ed. 1996, Vol. A 28, pp. 122-150).
- photo toners generally contain resins based on Polyesters or styrene-acrylate copolymers.
- a charge control agent the Support transfer of the toner from the photo-roll to the paper-base, are used e.g. quaternary ammonium salts for a positive charge and For example, aluminum azo complexes for a negative charge of the Toner powder used.
- the Toner powder small amounts of highly dispersed silicas are added.
- the toners are already in the thermoplastic Mixture of suitable black or color pigments added.
- styrene-acrylate resin type CPR 100, manufacturer Fa. 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: Fa. Timcal
- a charge control agent Copy Charge N4S, Manufacturer: Clariant GmbH
- This mixture has now become one Toner powder of average particle size 12 microns (100% ⁇ 20 microns) comminuted.
- the Toner powder were now still 0.5 parts by weight of a silica-based Flow agent (type HDK, manufacturer: Wacker) added. 5 g of this now free-flowing Mixture was mixed with 95 g of iron powder and into the reservoir of a Copier filled.
- Example 1 The procedure was analogous to Example 1. Instead of the one used in Example 1 Benzyl montanate wax was used herein according to the invention Reaction product of technical montanic acid and styrene oxide used (Acid number 18 mg KOH / g, dropping point 76 ° C) used. At the same time the Pigment content reduced by 25%. Otherwise, the procedure was as in Example 1. The prints showed the same color depth as a parallel according to Example 1 tested standard without wax. It follows that through the Wax addition a more effective pigment dispersion is achieved.
