Definitions

  • Finishes serve to improve the physical fastness of leather and imitations of leather, such as rub fastness, shock resistance and heat resistance. In addition, they give these materials a solid external appearance such as shine, smoothness and surface feel. Finishing agents for leather and imitations of leather are already known in large numbers, e.g. based on protein substances, nitrocellulose and polyurethanes.
  • thermoplastic primers if highly crosslinked polymer dispersions are used as binders when dressing the leather, or even better, if reactive binders are crosslinked on the leather using suitable polyfunctional compounds (see, for example, DE- OS 3 544 001 and DE-OS 3 711 415).
  • Primers with such strongly crosslinked polymer dispersions seal off strongly and are therefore only slightly swellable by water and solvents. The adhesion of the finishing layers is therefore problematic. Finishing agents that are to be applied to cross-linked reactive primers must therefore have particularly good adhesion to the substrate.
  • toluene, xylenes, isopropanol, ethanol, methyl and ethyl glycol, benzyl alcohol, diisobutyl ketone and in particular 2-ethyl-n-hexylacetate are particularly suitable as solvents or blending agents.
  • alcohols and glycols are preferred.
  • the physical properties of the finishing agents such as flow, drying speed and the like are due to the amount of low boilers (isopropanol, ethanol), medium boilers (methyl, ethyl glycol) or high boilers (benzyl alcohol, 2-ethyl-n- hexylacetate) controllable. They are used in amounts from 0 to about 985 g / kg of finishing agent.
  • the use of other solvents is of course within the scope of the invention.
  • the components are combined with solvents and blending agents and stirred until the cellulose acetobutyrate has completely dissolved.
