Abstract: An indexing image for craft stamps that is opaque to the eye but transparent to UV light is produced by printing a wavelength-specific solvent-based ink on the stamp substrate. This eliminates the step of printing a separate adhesive-backed indexing image sheet and applying it to the substrate.

Abstract: Negatives and laminates containing negatives for exposing liquid photopolymers in UV flexographic plate making are created by printing opaque images directly onto the protective or release cover films used in plate making processes. Combining negatives and cover films in this way eliminates two layers and two interfaces in the exposure process, reducing cost and improving quality.

Abstract: Negatives, and laminates containing negatives, for exposing liquid photopolymers in UV flexographic plate making are created by printing opaque images directly onto the protective or release cover films used in plate making processes. Combining negatives and cover films in this way eliminates two layers and two interfaces in the exposure process, reducing cost and improving quality. By bringing the negative images as close as possible to the liquid photopolymer, printed dots of “digital quality” are created.

Abstract: A laminate of an artificial nail bound to a natural nail with a layer of a cyanoacrylate adhesive formulation containing a thickener, a stabilizer, and a plasticizer is as strong and durable as similar laminates but is flexible and pliable enough to bend without cracking.

Abstract: A flexography substrate for making I-plates with liquid photopolymers has, in addition to the tie-coat applied to one side to hold the photopolymers in place on the substrate, a micro-porous coating applied to the other side, enabling a masking image to be applied to it using an inkjet printer. In this way, one single sheet of film performs the dual role of substrate and I-plate masking film. By eliminating a sheet of film, the invention provides cost, quality, and environmental benefits.

Abstract: Two methods using two respective laminates produce flexographic printing plates with flat top dots from sheet photopolymers. The methods use a preliminary laminate to isolate the photopolymer surface from the ambient air. A third method enables images to be transferred to non-porous surfaces.

Abstract: This disclosure relates to a photosensitive composition useful in preparing water-developable, relief printing plates and other photosensitive articles. The compositions comprise an unsaturated polyurethane pre-polymer, which is the reaction product of at least one polyether diol, at least one aliphatic diisocyanate, at least one hydroxyl-functionalized mono-, di- and tri-(meth)acrylate, and a particular photoinitiator. The resulting photosensitive resin compositions have reduced rates and levels of yellowing if subjected to additional UV-light or sunlight after processing.

Abstract: The invention relates to reactive monomers containing 2-cyanopenta-2,4-dienoate and methacrylic or acrylic double bonds in their molecules. The reactive monomers are easily polymerizable in a variety of ways. The polymerized reactive monomers can form strong adhesive bonds between a variety of substrates. The adhesive bonds are water and humidity resistant, heat resistant, impact and peel resistant and can sustain large loads and stresses. The polymerized reactive monomers are applicable as structural and industrial adhesives, medical and surgical adhesives and optical fibre coatings, and can be used in the manufacture of positive or negative photo or electron beam resists.

Abstract: A solid cyanoacrylate adhesive composition is disclosed which can be applied to a substrate in solid form and which polymerizes into an adhesive polymer upon liquefying. Preferably the solid cyanoacrylate composition liquefies at temperatures slightly above room temperature and polymerizes upon liquification. &egr;-caprolactones are used as a solidifying polymer with cyanoacrylate monomers and other additives to form the solid cyanoacrylate adhesive composition. The solid cyanoacrylate adhesive composition is easy to apply, especially stable in solid form and is capable of use in a variety of industrial, consumer and medical applications.

Abstract: The present invention provides pure, storage stable, reactive esters of 2-cyanopenta-2,4-dienoic acid and the adhesives and polymers thereof. The monomers of the present invention have the formula: where R is alkyl, alkenyl, alkynyl, alkoxyalkyl, alkenyloxyalkyl, alkynyloxyalkyl, poly(oxyalkyl), aryl, cycloalkyl or a heterocyclyc radical. R may also be one of the foregoing moieties substituted with one or more of the other moieties; this includes the case of the substituent itself being substituted, and may also contain halogens. The reactive monomers of the present invention can be formulated into adhesives by incorporating certain modifiers and additives such as polymeric thickeners, viscocity regulators, plasticizers, thixotrophic agents, compatibilizers, adhesion promoters, pigments and colorants, fillers, deodorants and perfumes. They can also be used in composition with other monomers containing a reactive double bond such as for example cyanoacrylates.

Abstract: A methyacryloyl or acryloyl derivative of an ester of cyanoacetic acid may be of the formula: CN—CH2—COOR2OCOCR1═CH2. R1 may be H or CH3, and R2 may be one of the group of moieties including alkyl, alkenyl, alkynyl, alkoxyalkyl, poly (oxyalkyl), aryl, cycloalkyl, and heterocyclyc radical, or substitited combinations thereof. Further, R2 may include between 1 and 16 carbon atoms or heteroatom ring members.

Abstract: Bioabsorbable cyanoacrylate-based tissue adhesives containing bioabsorbable copolymers are disclosed. The copolymers are preferably derived from &egr;-caprolactone, lactide and glycolide monomers or from butyl 2-cyanoacrylate, glycolide, lactide, &egr;-caprolactone monomers. The adhesives are characterized by increased biodegradability, increased viscosity and increased flexibility. The adhesives are useful for wound and incision closure, and for medical devices, including implants.

Abstract: Cyanoacrylate preparations for medical and surgical applications are sterilized by heating in a suitable container at a temperature of at least 160.degree. C. The preferred container is a squeezable aluminum tube and the preferred temperature is above 170.degree. C. Cyanoacrylate adhesive compositions sterilized by heat have improved shelf life compared to those sterilized by ionizing radiation.
