A solid electrolyte having solvent ligands and polymer ligands coordinated with metal ion exhibits improved stability and resistance to volatilization or migration of liquid phase components. The solid electrolyte of this invention comprises a metal salt to provide a metal ion which is coordinated with a molar ratio of ligands appropriate to the metal ion. For lithium ion the ratio is between about 1:3 and about 1:6 moles of lithium salt to moles of ligands, where the ligands comprise about 10% to about 60% by weight structural network crosslinked polymer and about 40% to about 90% by weight aprotic solvent.

摘要:
A process is provided for producing a coating composition containing microcapsules having a hydrophilic core material for use in the manufacture of pressure-sensitive carbonless transfer papers comprising the following steps of preparing a hydrophobic emulsion component by dispersing an emulsifier in a radiation curable hydrophobic liquid, preparing a hydrophilic emulsion component by dispersing a first wall-forming material in a hydrophilic liquid containing at least one chromogenic material being soluble in the hydrophilic liquid, the first wall-forming material being reactive with a second wall-forming material to form a polymeric capsule wall, the polymeric capsule wall being substantially insoluble in the hydrophilic and the hydrophobic liquids and mixing the hydrophobic emulsion component with the hydrophilic emulsion component to form an emulsion containing droplets of the hydrophilic emulsion component dispersed in the hydrophobic emulsion component. The second wall-forming material is then added to the emulsion with agitation, the agitation continuing for a period of time sufficient to allow the first and second wall-forming materials to react to form a dispersion of microcapsules in the hydrophobic emulsion component, the microcapsules having cell walls substantially impermeable to the hydrophobic and the hydrophilic liquids. A process is provided for producing a pressure-sensitive carbonless transfer paper comprising the further steps of applying the coating composition to a substrate and curing the coating composition by subjecting the coating composition on the substrate to radiation for a period of time sufficient to cure the radiation curable hydrophobic liquid, thereby producing a tack-free resinous film on the substrate. A novel coating composition is produced comprising microcapsules having a hydrophilic core material dispersed in a radiation curable hydrophobic liquid. A pressure-sensitive carbonless transfer sheet is produced comprising a substrate having a plurality of surfaces, at least one of the surfaces being coated with a tack-free resinous film comprising a radiation cured resin having dispersed therein microcapsules containing a hydrophilic liquid containing at least one chromogenic material, the chromogenic material being soluble in the hydrophilic liquid.

A process is provided for producing a radiation curable coating composition containing microcapsules comprising the steps of preparing a dispersion of substantially discrete microcapsules in a continuous phase, the continuous phase comprising a liquid volatile solvent, preparing a liquid radiation curable suspending medium, the liquid radiation curable suspending medium comprising one or more ethylenically unsaturated organic compounds having at least one terminal ethylenic group per molecule, mixing the dispersion of substantially discrete microcapsules in the continuous phase and the liquid radiation curable suspending medium with turbulent agitation to form an intimate mixture of the dispersion of microcapsules and the liquid radiation curable suspending medium, and applying heat and vacuum to the mixture, while maintaining the agitation, until the liquid volatile solvent is substantially removed from the mixture to form a dispersion of substantially discrete microcapsules in the liquid radiation curable suspending medium, the heat being applied to maintain the mixture at a temperature above the boiling point of the volatile solvent at the vacuum level.
