The invention provides a delamination-resistant embedded silicone hydrogel contact lens having an insert that is embedded in a silicone hydrogel bulk material. The insert is made of a crosslinked polymeric material having a refractive index higher than that of the silicone hydrogel bulk material by at least 0.07 and comprises a diffractive structure disposed on one of the front and back curve surfaces of the insert for providing a diffractive power that contributes to the overall optical power of the contact lens.

Diffractive contact lenses

The invention provides a class of high RI polysiloxane vinylic crosslinkers. Each of the polysiloxane vinylic crosslinkers of the invention comprise (1) a polysiloxane segment comprising dimethylsiloxane units and aryl-containing siloxane units each having one methyl substituent and one organic substituent having up to 45 carbon atoms and at least one aryl moiety which is linked to Si atom through a linker having at least 2 (preferably 3) carbon atoms; (2) ethylenically-unsaturated groups. The invention also provides an insert or silicone hydrogel contact lens which comprises a crosslinked polymeric material comprising repeating units of at least one of such a class of high RI polysiloxane vinylic crosslinkers.

Polysiloxane vinylic crosslinkers with high refractive index

The invention is generally related to a soft contact lens which comprises a hydrogel lens body and a coating of a hydrophilic copolymer thereon and to a method for producing the same. The hydrogel lens body comprises or is made of a polymeric material having 1,2- and/or 1,3-diol moieties, and the hydrophilic copolymer comprises arylborono-containing repeating units each having a boronic acid group. The coating is covalently-attached to the hydrogel lens body through cyclic boronic ester linkages each formed between one boronic acid group and one 1,2-diol or 1,3-diol group. The soft contact lens has a surface lubricity higher than the surface lubricity of the lens body.

Contact lenses with a lubricious coating thereon

The invention is related to a class of hydrophilic polymers each comprising one sole thiol-containing terminal group. The hydrophilic polymers are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating and can find particular use in for producing water-soluble highly-branched hydrophilic polymeric material useful for producing water gradient contact lenses.

Hydrophilic copolymer with one thiol-containing terminal group

A prepreg which is capable of being cured-in-place into a solid surface by irradiation, heating or a combination of the two is prepared. The cured-in-place solid surfaces can be used as veneer cladding for rigid substrates such as floor and wall tiles, kitchen and bath counter tops, sinks, cabinet door veneers, bath surrounds, architectural surfaces such as columns and roofs and the like.

Prepregs and cured in place solid surfaces prepared therefrom

A composition capable of radiation activated catalysis is provided. The composition comprises a metal compound, a mercapto compound and an olefinic compound. Radiation curable urethane compositions comprising the disclosed composition are also provided. The radiation curable urethane compositions comprise the disclosed composition, a hydroxyl compound and an isocyanate compound. Activation of the composition by radiation in a urethane formulation provides for an efficient method of curing the urethane composition. Coating and adhesive compositions comprising the radiation curable urethane compositions are also provided. In addition, methods for coating and bonding substrates are disclosed.

Composition capable of radiation activated catalysis and radiation curable urethane containing the composition

The invention is a pressure sensitive adhesive (PSA) composition, which is the ultraviolet radiation (UV) cured reaction product of a polyester-polyether-based urethane acrylate, one or more acrylate monomers, and a UV photosensitizer. The polyester-polyether-based urethane acrylate is the reaction product of between about 50 and 90 wt-% of a polyester diol having a molecular weight ranging from about 500 to 3200; between about 10 and 50 wt-% of a polyether polyol having a molecular weight ranging from about 1000 to 6000; between about 1 and 5 wt-% of a hydroxy-functional acrylate; and a polyisocyanate.

Self-photoinitiating multifunctional acrylates

The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. The binder system comprises (a) a compound containing at least two active methylene hydrogen atoms, (b) an organic polyisocyanate (c) a reactive unsaturated acrylic monomer and/or polymer, (d) an oxidizing agent, and preferably (e) an epoxy component. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes that are used to make metal castings.

The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from .gtoreq.1:1 to .gtoreq.13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
