摘要： 2-Methyl-4,4a-dihydro-3H-carbazolium salts that are useful as dye precursors and dyes derived from those precursors are disclosed. The salts are described by the formula ##STR1## wherein R.sup.1 represents an alkyl, aryl, sulfoalkyl, carboxyalkyl, sulfatoalkyl, alkoxyalkyl, acyloxyalkyl, dialkylaminoalkylene, cycloaminoalkylene, acyl, or alkenyl group having from 1 to 18 carbon atoms; R.sup.2 represents an alkyl group having up to 18 carbon atoms; R.sup.3 represents hydrogen or an alkyl group having from 1 to 18 carbon atoms; R.sup.4 represents hydrogen or an alkyl group having from 1 to 18 carbon atoms; R.sup.5 represents hydrogen, nitro, carboxyl, sulfo, hydroxy, halogen, phospho, or an alkoxy, thioalkoxy, oxyalkyl, acyl, alkyl, aryl, or amino group having up to 18 carbon atoms; wherein any two groups R.sup.5, or R.sup.4 and a group R.sup.5, or R.sup.1 and R.sup.4 may together form a substituted or unsubstituted aryl, heteroaryl, aliphatic, or heteroaliphatic ring; X represents an anion; and a and b represent positive integers such that a equals b.The salts have a partially saturated ring system that rigidifies the chromophore in the precursor and in dyes derived from it. The rigidified chromophores have narrowed absorption bands relative to corresponding non-rigid chromophores. Dyes prepared from the dye precursors of the invention typically have good solubility in non-polar solvents.

摘要： A black donor for use in a laser addressable thermal transfer system, wherein the black donor comprises a substrate having coated thereon at least one black color layer comprising a binder and colorants. The colorants include a non-infrared absorbing black dye or pigment and about 10% to about 50% of a carbon black pigment, based on the total weight of the colorants in the black color layer.

摘要： A structured surface is formed with the method of the present invention. The method of making this structured surface includes the steps of applying an ablatable radiation sensitive coating on the major surface of the substrate, and exposing the ablatable radiation sensitive coating to radiation such that exposed portions of the ablatable radiation sensitive coating ablate from the substrate to form a structured surface. The structured surface then includes a substrate and a pattern of structures framed by at least one separation bank. The method may also include the steps of depositing a flowable material on to the structures and the separation bank to form a pattern of flowable material in the structures.
