The present invention relates to a photochromic polymer for photo recording purposes comprising polymethacrylate, and having the following general formula: ##STR1## wherein R is --(CH.sub.2).sub.o --X--C.sub.6 H.sub.4 --Z--C.sub.6 H.sub.4 --R.sub.1, wherein R.sub.1 is an electron acceptor, such as cyano, alkoxy having 1 to 8 carbon atoms, halosubstituted alkoxy having 1 to 8 carbon atoms, halogen (F, Cl), hydroxy, esters of the formula --OOC--C.sub.n H.sub.2n-1, --CO--C.sub.n H.sub.2n-1, wherein...

The use of 2-methyl-3-cyclohexylpropanol, esters thereof or mixtures thereof as fragrance materials is disclosed. The subject materials possess unique fragrance notes and are cost-effective materials. The esters are novel compounds.

The invention relates to conductive heaters, and has its objective to provide a material that exhibits a uniform heating effect over the full area of the heater, relatively free from hot and cold spots, a further objective being to maintain the heater pliable. These objectives are met by a conductive material comprising finely divided carbon particles uniformly dispersed in an elastomeric carrier there being carbon particle levels of 20% to 75% by dry weight to carrier levels. Preferably, the ca...

Construction materials suitable for use as, or in, a wearing course for children's play areas, games areas and like purposes, comprise an agglomerate of granules of a thermoplastic elastomer. The granules of the agglomerate are conveniently held together by means of a polyurethane or other binding agent or by being melded together. The thermoplastic elastomer is, for example, a block copolymer of the styrene type, for example a styrene-butadiene-styrene block copolymer. The granules of the therm...

A transfer material and method of use for transferring monochrome and full colour images produced by a xerographic process or dry toner printing onto a substrate. The process requires the use of film form polymethylpentene material as the transfer material which is used to transfer the xerographic or dry toner image onto the substrate with the application of heat and pressure.

The present invention is directed to encapsulated fragrance materials. The fragrance materials are comprised of high Clog P materials or high Clog P fragrance materials along with high Clog P solvent materials. The encapsulated fragrance and solvent materials can then be further coated with a second coating, preferably a cationic coating. The selective use of solvents enables the fragrance and fragrance materials to remain in the capsules for extended periods of time without leaching from the ca...

Photoreactive dendrimers comprising a core portion, branching units and terminal groups, wherein at least one terminal group and/or branching unit is a photoreactive group and wherein the photo reactive groups include preferably cinnamates, coumarins, benzylidenephthalimidines, benzylideneacetophenones, diphenylacetylenes stilbazoles, uracyl, quinolinone, maleinimides, or cinnamylidene acetic acid derivatives and are able to undergo photocyclization, in particular [2+2]-photocyclization.

Puffed triticale is used alone or with tobacco to provide smoking materials.

The invention is concerned with a process for improving the smoking properties of a tobacco smoking material in which the tobacco material is subjected to treatment with at least one amylolytic enzyme capable of converting the starch contained in the tobacco into sugar. The amylolytic enzyme or a source thereof may be added to the tobacco material, for example to an aqueous dispersion of the latter.

A material contaminated with a solvent is treated with a hydrofluorocarbon to remove the contaminant. A preferred hydrofluorocarbon is tetrafluoroethane. Apparatus for carrying out the process is also described.
