Abstract: A low viscosity energy curable epoxy resin composition essentially free of solvent for preparing an ink composition comprising: (a) at least one divinylarene dioxide compound, (b) at least one cycloaliphatic epoxy resin, (c) at least one vinyl ether compound, (d) at least one cationic photoinitiator, (e) at least one pigment, and (f) optionally, at least one oxetane; wherein (i) the viscosity of the curable composition is less than or equal to about 50 mPa·s at 25° C., (ii) the composition cures at a relative humidity of greater than 30%, and (iii) the composition cures with an increase in cure time of less than 100% when the composition is cured at a relative humidity of at least 70% compared to that of a composition that is cured at a relative humidity of less than or equal to 45%. The curable epoxy resin composition is useful, for example, for preparing an ink composition; and more specifically for preparing a solventless low viscosity UV curable inkjet ink composition.

Abstract: A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group. Such polymers impart qualities of environmental or protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability, flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, and/or reduced moisture pick-up. Additionally, the coatings are optically clear, easy to apply either neat, in a solvent or otherwise, have relatively low cure temperatures for their temperature resistance, and exhibit insulating and planarizing capabilities.
