    摘要: Disclosed are thermally-stable, anthraquinone colorant compounds (dyes) which contain one or more vinyl groups which render the compounds copolymerizable with reactive vinyl monomers to produce colored, polymeric compositions such as acrylate and methacrylate polymeric materials. The compounds possess good fastness (stability) to ultraviolet (UV) light, good solubility in vinyl monomers, good color strength and excellent thermal stability. Also disclosed are (1) coating composition comprising (i) one or more polymerizable vinyl compounds, (ii) one or more of the dye compounds described above, and (iii) a photoinitiator and (2) polymeric materials, i.e., polymers derived from one or more acrylic acid esters, one or more methacrylic acid esters, one or more other polymerizable vinyl compounds or mixtures of any two or more thereof, having copolymerized therein one or more of the anthraquinone colorant compounds.

    摘要: Disclosed are thermally-stable, red, anthraquinone colorants which contain one or more ethylenically-unsaturated, photopolymerizable radicals and which may be copolymerized with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The compounds possess good stability to ultraviolet light, good solubility in vinyl monomers, good color strength and thermal stability. Also disclosed are acrylic polymeric materials, i.e., polymers derived from acrylic acid esters, methacrylic acid esters and/or other copolymerizable vinyl compounds, having copolymerized therein one or more of the colorant compounds of the present invention.

    摘要: An invisible indicia or encoded information is imprinted on a substrate using a compound which produces a fluorescence at a wavelength greater than about 650 nm when exposed to near infrared radiation. The information covered by a layer of material that reflects or absorbs a substantial amount of the visible and UV radiation illuminating its surface.
