Cholesteric laminate material for production of flake pigments and coating materials comprises two cholesteric layers with an interlayer of adhesive material |
摘要 |
An adhesive layer (B) forms the interlayer between similar or different cholesteric layers (A1) and (A2) in a cholesteric laminate material with the layer sequence A1/B/A2. Independent claims are also included for: (i) a process for the production of cholesteric laminate material by: (a) coating a base with a first coating material which is hardened to form layer (A1); (b) coating (A1) with a second material containing heat- and/or pressure-activated adhesive(s) to form a laminate A1/B with adhesive layer (B); (c) coating another base with a third coating material which is hardened to form layer (A2); (d) laminating (A2) with (A1/B) under elevated pressure and/or temperature to form laminate A1/B/A2; (e) stripping off the second base; and optionally (f) stripping off the first base; (ii) a process for the production of multilayer cholesteric flake pigments with the layer sequence A1/B/A2 by milling the above material to a particle size of up to 200 microns; (iii) cholesteric flake pigments obtained by this process; and (iv) compositions and coating materials containing these multilayer pigments. |
