Abstract
A method for the manufacture of a matrix on a substrate, said matrix being particularly useful in the formation of color filter elements, the process comprising the steps of: PA1 a) providing an imageable article comprising a substrate having on at least one surface thereof a black layer, PA1 b) directing energy of sufficient intensity at said black layer to transparentize black layer, PA1 c) said directing of energy being done so that black layer is removed in some areas, but is not removed in other areas so that borders of black layer surround areas from which black layer has been removed. A preferred method deposits colorant material within the open areas of the matrix by thermal transfer, e.g., laser induced thermal transfer, of colorant material to form a filter element.
