Tooth pastes comprising: a) imido-alkanpercarboxylic acids under the form of adducts with cyclodextrins, preferably beta-cyclodextrins, b) aliphatic carboxylic acids having a solubility in water at room temperature higher than or equal to 5% by weight and containing one or more carboxylic functions.

Print pastes and dye pastes for printing and dyeing fibrous materials based on organic dispersion of cross-linkable copolymers as binders for the pigments. The disperse copolymers, which can be used as binders without emulsions, are prepared by polymerization of (a) monomers which bear N-methylol groups or N-alkoxymethyl groups with (b) comonomers which do not contain any of the groups specified under (a), in (c) an organic liquid in which the copolymer is insoluble, and in the presence of a cop...

A process for forming a paste suitable for the preparation of dispersions and coatings is disclosed, said process comprising (1) dissolving a selectively hydrogenated monoalkenyl arene (A) - conjugated diene (B) block polymer in a first solvent, which first solvent is a good solvent for both the A blocks and the B blocks, (2) adding a second solvent to the solution, wherein said second solvent is a good solvent for the A blocks and a poor solvent for the B blocks, therein forming a suspension of...

A metallising paste, suitable for forming an adherent electrically-and thermally-conductive metal-containing deposit on a ceramic surface and having one application in providing screen-printed microcircuit conductors and a further application in providing heat abstracting pads, or "heat sinks," applied to the underside of microcircuit substrates, comprises a heat-vaporizable liquid medium containing as powder a glaze material and a component selected from aluminum or an alloy thereof, wherein th...

A metallising paste for screen-printing microcircuitry comprises a heat-vaporizable inert liquid medium containing, in powder form, at least one constituent selected from a noble metal, a noble metal alloy, an oxide of a noble metal and an oxide of a noble metal alloy, at least one constituent selected from copper and copper oxide, and a vitreous binder, the binder having a fusion temperature less than the melting temperature of the noble metal - copper oxide alloy formed on fusing the powder co...

A conductive paste is provided which is prepared by kneading a composition comprising silver metal powder, an organic vehicle, and a silver-titanium alloy powder contained in an amount of 0.1 to 6.0% by weight based on the amount of the silver metal powder.

The present invention provides a modeling paste comprising a latent material which can be applied as a thick layer to a substrate and which after activation rapidly crosslinks to a machinable surface.

Solder powders coated with a thin layer of parylene and solder pastes containing the coated solder powders are disclosed. The coated solder powders can exhibit a high degree of resistance to oxidation and to reaction with the flux contained in the solder paste without substantially interfering with the reflow characteristics of the solder.

Adhesives or pastes prepared by dissolving or dispersing uniformly a pullulan ester and/or pullulan ether in water or in a mixture of water and acetone in an amount between 5 percent and 40 percent of the solvent are moisture-proof and have better water retention, stability and adhesiveness than conventional starch pastes or glue. They are also non-toxic and resistant to the growth of fungi.

Pigment pastes, containing as the binder 3-20% by weight of a polyester-polyurethane, which is obtained by reaction of a polyesterpolyol of average molecular weight 500-3,000, based on hexanediol or butanediol-1,4 and adipic acid with isphorone diisocyanate or dicyclohexylmethane-4,4'-diisocyanate and subsequent lengthening of the molecular chain by means of isophorone-diamine and as the solvent at least 20-90% by weight of ethylene glycol monoalkyl ether, are universally suitable for the colour...
