The present invention relates to a method of using radiation and (in one embodiment) solar energy and UV radiation to convert natural products, for example derivatives of vegetable oils, to lower molecular weight hydrocarbons. The invention further relates to a process whereby these hydrocarbons can be converted to vinyl monomers and used in the formation of plastics, solvents, fuels and the like.

Photochemical method for producing hydrocarbons

The present invention is a method and apparatus for remote curing of resin-coated surfaces and articles by means of a vaporous curing agent. The method of the present invention includes the steps: (a) providing a surface of the substrate with a layer of a coating precursor comprising a curable material and a stabilized curing agent that is adapted to react with a gaseous, vaporous or aerosol initiating agent to activate the stabilized curing agent so as to cause the curable material to undergo a curing reaction; (b) subjecting the coating precursor to the gaseous, vaporous or aerosol initiating agent for sufficient time to initiate the curing reaction, and allowing the coating precursor to form a cured coating on the substrate. Another variation of the method of the present invention involves the reversal of the positions of the active compounds utilizing the interaction between the gaseous, vaporous or aerosol curing agent and coating precursor comprising a curable material and initiating agent.

A liquid transfer article is provided including a support assembly and an imaged surface formed directly on the surface of the support assembly by digital photopolymerization. The support assembly is in the form of a polymeric base, and the liquid transfer article is formed by providing a liquid photopolymer on the surface of the base and then irradiating the polymer with a light source to form the image. The liquid transfer article is reimagable and may be used in gravure printing processes, as well as other printing applications.

A method for forming selectively colored printing plates using photosensitive recording elements is disclosed wherein the photosensitive recording element contains a photopolymerizable recording layer comprising a photopolymerizable monomer, a radical photoinitiator, a color former, and a color photoinitiator. A method for producing a printing plate from the photosensitive recording element involves exposing the back surface of the recording layer to a dose of actinic radiation, imagewise exposing the front of the photopolymerizable recording layer to another dose of actinic radiation thereby forming exposed and unexposed areas on the front of the recording layer wherein the exposed areas are cured and undergo a color change by exposure to the actinic radiation, and then removing the unexposed areas of the imagewise exposed recording layer thereby forming an image in relief wherein the image portion and the non-image portion are of different color and wherein the contrast between these portions due to the color difference is visually detectable.

Method for producing selectively colorable printing plates

Selectively colorable compositions and a method for forming selectively colored polymeric bodies using such compositions are disclosed. In accordance with the invention, a selectively colorable polymerizable composition comprising a leucobase color former is irradiated with light of a particular wavelength and specific intensity for a specified duration. Exposure to actinic radiation cures the composition and activates the color former. Exposure to higher dosages of actinic radiation can bleach the composition. The irradiation dosage can be varied to selectively color the polymeric body whereby the resultant color of any particular area depends on the exposure dose received at that location. By varying the dose, a polymeric body can be prepared having distinctly colored elements at specific locations.

Selectively colorable polymerizable compositions

The present invention relates to a thermally and cationically curable composition containing triarylcyclopropenylium salts and a solvent that is a Lewis base which contains acidic hydrogen and their use as thermal initiators in polymerization processes. The present invention includes the polymerization of epoxy resins, vinyl ethers and other cationically curable monomers.

Selectively colorable polymerizable compositions and a method for forming selectively colored polymeric bodies using such compositions are disclosed. In accordance with the invention, a selectively colorable polymerizable composition comprising both a leucobase color former and a leuconitrile color former is irradiated with light of a particular wavelength and specific intensity for a specified duration. Exposure to actinic radiation cures the composition and activates the color formers. The irradiation dosage can be varied to selectively color the polymeric body whereby the resultant color of any particular area depends on the exposure dose received at that location. By varying the dose, a polymeric body can be prepared having distinctly colored elements at specific locations.
