Abstract: An imaging sheet used for achieving color balance in a full-color imaging system is disclosed. The sheet is characterized by utilizing three sets of microcapsules, each containing a different colorless image-agent and a photohardenable or photosoftenable composition, and a corrective dye associated with the substrate. Association of the corrective dye with the substrate achieves color balance by equalizing the speed of the different colorless color-forming microcapsules.

Abstract: Plants are protected from insects and mites by the application of tall oil neutrals to the plants. The method can prevent insects and mites from eating on the plants, sterilize the insects and mites, or destroy the insects and mites.
Abstract: A process for laminating two or more transparent or translucent substrates or one transparent and one opaque substrate together which comprises the steps of:coating a photohardenable composition on one surface of a first translucent substrate, said photohardenable composition comprising a free radical addition polymerizable or crosslinkable compound and a dye-counter ion complex, said complex being capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of said compound, and preferably being photobleachable,applying a second translucent substrate to said photohardenable composition such that said photohardenable composition is interposed between said first translucent substrate and said second translucent substrate, andexposing said substrates to actinic radiation.
Abstract: The present invention provide a dye-sensitized photopolymerizable composition comprising a free radical addition polymerizable material, and a photoinitiator, the photoinitiator consisting essentially of a photoreducible dye, a thiol, and an N,N'-dialkylaniline.
Abstract: A method for treating an imaging sheet is disclosed. The method includes the steps of providing an imaging sheet having coated on one of its surfaces a layer of microcapsules, the microcapsules containing a radiation curable composition and having an image-forming agent associated therewith, heating the sheet; and image-wise exposing the layer of microcapsules to actinic radiation; wherein the heating step is performed prior to or after the image-wise exposing step. The method reduces or removes damage defects on the imaging sheet and, in some instances, extends the dynamic range of the image-forming agents.
