Polycarbonates formed at least in part from dihydroxy aryl ketones and optionally benzylic hydrogen containing aromatic diols may be crosslinked by exposure to electromagnetic radiation such as ultraviolet light, thereby imparting improved solvent resistance.

Polycarbonate compositions

An optical memory storage media is described, e.g. a compact disc. A method of preparing the media (e.g. discs) is also taught. The storage media is formed from a substrate material having tightly bonded to the surface a highly reflective soft metal alloy formed of, for example, an alloy including at least five percent by weight of each of at least two metals selected from the group consisting of cadmium, indium, tin, antimony, lead, bismuth, magnesium, copper, aluminum, zinc and silver.

Optical recording medium

Optical information recording medium containing a metal alloy as a

An article and method for its perparation is disclosed wherein the article comprises a substrate having at least one planar surface on which is disposed a thermally decomposable metallo-organic compound in active association with a photosensitive dye. The article can be easily processed with, for example, a source of energy such as a laser beam to encode information or produce electroconductive lines.

Dye-enhanced deposition of elemental metals and metalloids on substrates

A water-insoluble pigment comprising a complex of a water-insoluble inorganic substrate exhibiting anion exchange properties, a water-soluble dye, and an anionic amphipathic material is disclosed.

Insoluble pigments and preparation thereof

A water-insoluble pigment comprising a complex of an inorganic water-insoluble anion exchange material and a water-soluble dye is disclosed. The anion exchange material may be represented by the general formula:

The invention is an oxalloy consisting essentially of about 5 to about 57 weight percent magnesium or aluminum and about 0.5 to about 10 weight percent of one or more alloying materials selected from the group consisting of B, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, As, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Ga, In, Sn, Sb, Hf, Ta, W, Re, Os, Ir, Pt, Au, Tl, Pb, Bi, Th, and rare earths; and the remainder oxygen. The invention also includes a method for forming the above oxalloys and a substrate coated with the oxalloys of the present invention.

Corrosion resistant magnesium and aluminum oxalloys

Novel aminoalkyl hydantoins and glycidyl derivatives thereof are prepared from previously unknown 3-(amidoalkyl) hydantoins.

Aminoalkyl hydantoins and glycidyl derivatives thereof

Method of making corrosion resistant magnesium and aluminum oxyalloys

A process to form polyethers from monoepoxides in the presence of a catalyst, said catalyst being formed from a photoactivated rhenium carbonyl coordination compound precursor.

Photoactivated catalytic polymerization of monoepoxides

A process to form silyl ethers by contacting a carbonyl compound with an organosilicon hydride under reaction conditions in the presence of a catalyst, said catalyst being a heated transition metal carbonyl coordination compound.

Thermal catalytic hydrosilylation of carbonyl compounds

A process to form silyl ethers by contacting a carbonyl compound with an organosilicon hydride under reaction conditions in the presence of a catalyst, said catalyst being formed from a transition metal carbonyl coordination compound precursor by irradiation at an appropriate wavelength.

Photoactivated catalytic hydrosilylation of carbonyl compounds

Polyether hydroxyl-containing compounds are prepared by reacting a monoepoxy-containing compound such as propylene oxide with a compound containing one or more OH and/or SH groups such as a low molecular weight adduct of glycerine and propylene oxide in the presence of a solid calcium naphthenate catalyst. The solid form of the catalyst is more efficient than the liquid form.
