专利摘要

There is provided a dispersion comprising a dispersion medium (phase l) and a disperse liquid phase II, wherein both phases I and II comprise a further dispersed phase III and this dispersed phase III comprises a release-active agent, wherein phase III has a fraction in phase II of from 5 to 20 wt %, based on the sum of phase II and phase III, wherein the dispersion has 3 phases following separation by centrifuging, these phases being discernible as phases having different transmittances (T). ......

权利要求: CLAIMS: 1. A dispersion comprising a dispersion medium phase I and a disperse liquid phase II, wherein both phases I and II comprise a further dispersed phase III and this dispersed phase III comprises a release- active agent, wherein phase III has a fraction in phase II of from 5 to 20 wt %, based on the sum of phase ll and phase III, wherein the dispersion has at least 3 phases following separation by centrifuging, these phases being discernible as phases having different transmittances (T). 2. The dispersion according to claim 1, wherein the two phases I and II at room temperature are 1 0 soluble in one another to an extent of less than or equal to 0.5 wt %, based on the respective other phase. 3. The dispersion according to claim 1 or 2, wherein phase I and phase ll have mass and phase I to phase II have a mass ratio of from 0.1:100 to 100:0.1. 1 5 4. The dispersion according to any one of claims 1 to 3, wherein phase II consists of water to an extent of more than 55 wt %. 5. The dispersion according to any one of claims 1 to 4, wherein phase I consists of a hydrocarbon or hydrocarbon mixture to an extent of more than 75 wt %. 2 0 6. The dispersion according to any one of claims 1 to 5, wherein phase III has a fraction in phase I of from 0.1 to 20 wt %, based on the sum of phase I and phase III. 7. The dispersion according to any one of claims 1 to 5, wherein phase III has a fraction in phase I of 2 5 from 1 to 7.5 wt %, based on the sum of phase I and phase III. 8. The dispersion according to any one of claims 1 to 7, wherein said release-active agent in phase III comprises one or more microwaxes, polyethylene waxes and/or ethoxylated polyethylene waxes. 3 0 9. The dispersion according to any one of claims 1 to 7, wherein said release-active agent in phase III comprises one or more microwaxes and/or ethoxylated polyethylene waxes. 10. A process for preparing the dispersion as defined in any one of claims 1 to 9, wherein a phase I and a phase II are provided, a release-active agent is dispersed as phase III into both of phases I and II, 3 5 and subsequently phases I and ll are mixed with one another. Date Regue/Date Received 2023-01-09 - 19 - 11. The process according to claim 10, wherein the two phases I and II at room temperature are soluble in one another to an extent of less than or equal to 0.5 wt %, based on the respective other phase. 12. The process according to claim 10 or 11, wherein a molten wax is used as releacc active agent. 13. A product comprising the dispersion as defined in any one of claims 1 to 9, wherein the product is selected from the group consisting of paints, inks, polymer dispersions and release agents.
