Abstract
A process for preparing a patterned, cross-linked, acrylic-polymer, film coating on a substrate; the process comprising the steps of: a) applying to the substrate by an ink-jet printing process a mixture comprising: i) one or more cross-linkable, thermally ink-jettable, water-dissipatable, precursor(s) for one or more cross-linked acrylic-polymer(s); ii) one or more cross-linker(s) capable of cross-linking the precursor(s) for the acrylic-polymer(s); and iii) one or more colorant(s); and b) thereafter curing the mixture in situ to form the patterned, cross-linked, acrylic-polymer, film coating on the substrate. Preferably the substrate is a color filter suitable for use in an LCD display and the mixture is applied in a single pass. The precursor may itself comprise polymers, e.g. acrylic polymers. Ink for use in this process and substrates printed by this process are also described.
