The invention provides a thermal transfer donor element comprising a support layer and a transfer layer supported by the support layer and comprising a binder containing carboxylic acid groups. The transfer layer includes an organic compound containing a plurality of hydroxyl groups with a hydroxyl group concentration of less than 18 mM/g and at least one connecting group, wherein the organic compound is free of any N,N-bis-(2-hydroxyethyl)amide and any rosin ester. In another embodiment, a method of using the donor element is provided, particularly in the manufacture of a color filter.

A polymeric film composition, which can readily be applied to a sheet-configured substrate and which resists creep at room temperature, even when the sheet/film combination is stored as a roll, is disclosed. The polymeric film composition has a viscosity of at least 3&times;10 Pa-s at a predetermined first lower temperature and at a shear stress of 10,000 Pa and a viscosity no greater than 1&times;10 Pa-s at a predetermined second higher temperature and at a shear stress of 50,000 Pa.
