摘要:
An ink composition comprising water, a water-dissipatable polyester, a disperse dye or a solvent soluble dye or a mixture of such dyes, a water-immiscible organic solvent and a water miscible organic solvent. The inks are useful in ink jet printers.
摘要:
An ink comprising water, a water-dissipatable polymer and a dye of formula (1), wherein R1 is optionally substituted alkyl or optionally substituted aryl; R2 is H, optionally substituted alkyl or optionally substituted aryl; R5 is H or optionally substituted alkyl; and R?3 and R4¿ are each independently optionally substituted alkyl or optionally substituted aryl, or R?3 and R4¿ together with the CH group to which they are attached from an optionally substituted 5- or 6-membered ring. Also claimed are dyes and ink jet printing processes.
摘要:
A process for preparing an optical filter comprising a coloured cross-linked polymeric coating on a transparent substrate, which comprises applying to the substrate, by a printing process, a mixture comprising one or more polymer precursor(s), and one or more dye(s) having one or more heterocyclic NH group(s) or one or more substituent(s) capable of forming a covalent bond with the polymeric precursor, and thereafter curing the mixture. The invention also provides formulations comprising one or more polymer precursors and dyes, optical filters, and a novel dye.
