Title: Photosensitive polymer derivatives and photosensitive elements containing them
IPC: G03F7/038
Filed: 1960-03-24
Abstract: The invention comprises polyvinyl acetals containing a plurality of intralinear -CH2CHOH-groups and a plurality of groups of the formula <FORM:0893616/IV (a)/1> wherein the free bands are attached to intralinear carbon atoms of the polyvinyl chain and R is alkyl, aralkyl, aryl, p-chloro-, p-sulpho-, sodium 2-sulpho-, 2-alkoxy- or 2-(C1 to C4) alkyl-phenyl, alpha-chlornaphthyl or alpha-methoxy- or ethoxynaphthyl.  The acetals may contain 10 to 90% based on the total number of vinyl alcohol units of -CH2CHOH- groups and 5 to 75% of 4-formyl-phenone acetal groups and may contain further groups such as ester or other acetal groups from aldehydes such as formaldehyde, acetaldehyde, benzaldehyde, o-sulphobenzaldehyde or sodium o-sulphobenzaldehyde.  The acetals are made by reacting the polyvinyl alcohol or copolymer with the formyl phenone or a derivative, e.g. an acetal in the presence of an acidic catalyst and two acetalizing agents may be present.  Coating compositions for use in making photosensitive elements may be made by dissolving the acetals in a volatile solvent, e.g. methanol, ethanol or isopropanol or mixtures of such solvents with water. The compositions may also comprise a hydrogen donor compound such as benzyl alcohol, methylphenyl carbinol, cyclohexanol, benzyhydrol, diphenyl methane, ringsubstituted toluenes, N-2-hydroxyethylformamide or hydroxy esters, or it may contain a phosphor, e.g. zinc sulphide or zinc cadmium sulphide particles, or fillers, e.g. organophilic silicas, bentonites, silica or powdered glass.  The composition may further contain a dye or a pigment, e.g. titanium dioxide, colloidal carbon, graphite, ceramics, clays, or metal powders.  Specification 864,041 is referred to.ALSO:p-Benzoylbenzal diacetate may be prepared by mixing p-methylbenzophenone with glacial acetic acid and acetic anhydride, cooling the solution in an ice-salt bath, adding concentrated sulphuric acid to the stirred solution, adding portions of chromium trioxide while maintaining the temperature below 10 DEG C., and pouring the mixture on ice.  p-Acetylbenzal diacetate is prepared similarly from p-methyl-acetophenone.  4-Formylbenzophenone may be prepared by refluxing p-benzoylbenzal diacetate with water, ethanol and sulphuric acid.  4-Formylbenzophenone ethylene glycol acetal may be prepared by refluxing 4-formylbenzophenone, ethylene glycol and p-toluenesulphonic acid with benzene while removing the water formed.

Patent GB-346978-A (GB)
Title: Emulsions of tar
IPC: C08L95/00
Filed: 1930-04-03
Abstract: Stable aqueous emulsions of tar, employed in surface-dressing of roads and pavements, are prepared by the use as emulsifying agents of aqueous solutions containing saccharates derived from mono-or di-saccharides in proportions not greater than 10 per cent of the tar.  The saccharates of sodium, potassium, calcium, strontium and barium or mixtures thereof are stated to be particularly suitable, the physical properties of the emulsions depending upon the saccharate or mixture used.  Calcium saccharate is stated to render the precipitated tar coating more weather-resistant.  The emulsifying agent may be formed during the emulsification process; for example, tar may be mixed first with lime and then with a dilute solution of treacle the proportions being such as ultimately to give tricalcium saccharate in the tar coating.  The emulsifying solution is preferably maintained slightly alkaline.  A specific example is as follows: 30 parts of a solution containing 1 per cent potassium hydrate and 5 per cent cane sugar are stirred with 60 parts of tar. Heat may be applied if necessary to melt the tar.  The prepared emulsion may be diluted, without precipitation, with solvents such as tetrachlorethane, carbon tetrachloride or xylene to produce a more rapidly drying coating.

Patent GB-756041-A (GB)
Title: Method of growing ethylene diamine tartrate crystals
IPC: C30B7/00
Filed: 1953-04-22
Abstract: Ethylene diamine tartrate crystals are grown from an aqueous solution of the salt to which sodium or potassium hydroxide has been added to raise the pH above 7.  The base may be added to a fresh solution or to an aged solution in which decomposition products have accumulated. The addition of the base facilitates the treatment of such solutions with absorbing agents such as active carbon to remove the decomposition products.  After the addition of absorbing agent and base the temperature of the solution is preferably gradually raised until the growth of crytals ceases and thereafter crystals are grown by slowly decreasing the temperature.  This avoids crystal deformities. Aged solutions which have been treated by addition of absorbing agent and base may be further purified by crystallizing ethylene diamine tartrate hydrate therefrom.
