- the paper coating slips can also contain so-called "co-binders" contain.
- cobinders examples include Starch, casein, gelatin, Alginates and soy proteins, as modified natural products Hydroxyethyl cellulose, methyl cellulose and carboxymethyl cellulose as well as cationically modified starch. But it can also conventional synthetic cobinders, e.g. on vinyl acetate or Acrylate base.
- These can e.g. in amounts of 0.1 to 10 wt .-%, based on the amount of pigment included.
- the components in mixed in a known manner the polymer generally in Form used as an aqueous dispersion, suspension or solution becomes.
- the water content in the paper coating slip is usually to 25 to 75% by weight, based on the total paper coating slip (including water).
- the paper coating slip can be made by conventional methods coating papers are applied (see Ullmann's Encyclopedia of Technical Chemistry, 4th Edition, Vol. 17, P. 603 ff).
- Papers have a high dry and wet pick resistance (adhesion of the paper coating slip). This makes them especially for the Suitable for offset printing, with the high tensile forces due to the printing ink claim the coated paper.
- the coated with the paper coating slips according to the invention Papers show good printability.
- the papers are special also suitable for offset printing processes.
- the template was heated to 85 ° C. and polymerized for 15 minutes. Then the monomer emulsion was metered in over 2 hours and the initiator (1% strength by weight solution of 6.29 g of sodium peroxodisulfate in H 2 O) was metered in over 2.5 hours. The mixture was then polymerized for a further 1 hour and cooled.
- the preparation corresponded to Example 1, but only 12 g Acrylic acid and an additional 12 g PMS are used.
- the preparation corresponded to Example 1, but only 6 g Acrylic acid and an additional 18 g PMS are used.
- Example 2 The preparation corresponded to Example 1, but none was Acrylic acid and 24 g PMS used instead.
- composition of the copolymers in% by weight is given in Table 1: example 1 2 3 4 nBA 52.9 52.9 52.9 St 43.3 43.3 43.3 43.3 AS 3.8 1.9 0.9 - PMS - 1.9 2.9 3.8
- a paper coating slip was prepared by stirring the following components. 10 Parts by weight of the copolymers 70 Parts by weight of hydrocarb (calcium carbonate) 30 Parts by weight Amazon (kaolin) 0.4 Parts by weight of polysalt (dispersing aid) 0.05 Parts by weight of NaOH 0.5 Parts by weight of CMC 7L2T (carboxymethyl cellulose)
- the solids content was adjusted to 65% by weight with water.
- a wood-free coating base paper with a basis weight of 70 g / m 2 was used as the base paper.
- the paper coating slip was applied on one side at 10 g / m 2 on a laboratory coating machine. Drying was carried out using an IR radiator. Before the application tests, the papers passed four times through a laboratory calender (a pair of rollers, line pressure: 2000 N / cm).
- the paper to be tested became strips in size 33 x 3 cm cut lengthways and these strips 15 hours at 27 ° C with a relative humidity of 50% stored in the climate room.
- the strips were then in a printing unit (IGT printability tester AC2 / AIC2) with a standard color (printing color 3808 from Lorilleux-Lefranc) printed.
- test strips are moving at a continuously increasing speed (maximum speed 200 cm / sec) through the printing unit guided.
- the speed is a measure of the dry pick resistance in cm / sec, with 10 tears after the start of printing from the paper coating slip (pick points).
- test strips were prepared and prepared as described above.
- the printing unit (IGT printability tester AC2 / AIC2) was set up so that the test strips with water before printing be moistened.
- the pressure was applied at a constant speed of 0.6 cm / s carried out.
- the papers to be tested are turned into samples with a size of Cut out 240 x 46 mm in the longitudinal direction.
- a corresponding amount of printing ink is placed on the inking roller given and allowed to run for 1 min. Then a thrust washer inserted and colored for 30 s.
- the printing speed is 1 m / s.
- a strip of paper will on a print sample with the printed paper strip again brought into the starting position. After a set Time will be the printing process without changing the printing disc started again. This process is repeated several times.
