Abstract: An optical recording medium has deposited on a substrate a recording layer incorporating therein a cyanine dye, preferably an indoline dye, and optionally incorporating therein an autoxidizable compound or a thermoplastic resin and/or a singlet oxygen quencher.

Abstract: Holographic flake pigments, processes for making the pigments, decorative coatings comprising the pigments, and articles comprising the decorative coatings are disclosed. The pigment comprises particles that (1) comprise an organic polymer and further comprise one or more volume phase holograms; and (2) have a thickness of about 1 micrometer to about 100 micrometers, an average diameter of about 10 micrometers to about 300 micrometers, and a thickness to diameter ratio of about 1:2 to about 1:60.

Abstract: An ablative recording element comprising a support having thereon, in order, a barrier layer and a colorant layer comprising a colorant dispersed in a polymeric binder, the colorant layer having an infrared-absorbing material associated therewith, and wherein the barrier layer comprises a vinyl polymer having recurring units of the following formula: ##STR1## wherein R.sup.1 and R.sup.2 each independently represents a halogen atom; a haloalkyl group with at least one halogen atom in its .beta.-position of the carbon to which R.sup.1 or R.sup.2 is attached; a ketal group; an acetal group; a thioketal group; a thioacetal group; a substituted or unsubstituted alkyl group; or a group containing a double or triple bond between any two atoms, one of which is adjacent to the carbon to which R.sup.1 or R.sup.2 is attached;with the proviso that at least one of R.sup.1 and R.sup.2 represents a group containing a double or triple bond between any two atoms, one of which is adjacent to the carbon to which R.sup.1 or R.

Abstract: A color diffusion transfer light-sensitive material is described including a support having thereon at least one light-sensitive emulsion layer associated with a dye image-forming material and an electron donor, wherein the dye image-forming material comprises at least one reducible dye-providing compound represented by formula (I) which releases a diffusible dye upon being reduced and tabular silver halide grains having a mean grain diameter of at least about 0.3 .mu.m, a mean grain thickness of less than about 0.5 .mu.m, and a mean aspect ratio of at least about 2 account for at least about 50% of the total projected area of the silver halide grains contained in at least one light-sensitive emulsion layer;PWR - (Time).sub.t - Dye (I)wherein PWR represents a group capable of releasing -(Time).sub.t -Dye upon being reduced; Time represents a group capable of releasing Dye through a subsequent reaction after being released as -(Time).sub.
