Abstract: A photographic element, for use in the color diffusion-transfer process, includes a neutralising system which comprises (i) a neutralizing layer and (ii) a timing layer positioned on or under the neutralizing layer in direct or indirect contact therewith such that aqueous alkaline diffusion-transfer developing solution reaches the neutralizing layer during the processing of the element through the timing layer and the two layers together reduce the pH of said solution; the timing layer has been formed by coating and drying a layer of an aqueous latex of particles of a co-polymer which latex has been produced by emulsion polymerization of (a) at least one polymerizable ethylenically unsaturated monomer having at least one free carboxylic acid group or a free phosphoric acid group or salt thereof and (b) at least one other copolymerizable ethylenic monomer, using a redox type of polymerization initiator comprising an oxidizing agent and a reducing agent and in the presence of a compound of a transition metal of atomic number 21 to 30, 39 to 38, 57 to 80 or 89 or more. Preferably a third ethylenic monomer of a specified general formula is also copolymerized. The presence of the compound of the transition metal (preferably iron, copper, nickel or cerium) gives a small size to the copolymer particles in the latex and this gives a timing layer of good temperature-compensating function and good adhesion to adjacent layers. Examples of the known synthesis of the copolymer are given. The neutralizing system is coated on a film support to form a cover sheet for a conventional type of laminate integral diffusion-transfer color film unit.

Title: Improvements in compositions and processes for sealing strengthening rods in mines and analogous works
IPC: C08L67/00
Filed: 1980-11-19
Abstract: Resinous compositions of the "single-component" type comprise as fillers, carbon black, 40 to 70% of chalk, and 10 to 40% of quartz sand, and sufficient of a resinous binder comprising unsaturated polyester resin, catalyst and inhibitor to form a matrix for the said fillers, the said percentages being by weight based on the weight of the composition. The carbon black makes it possible to achieve a much better compromise between the viscosity of the composition and its reactivity. Such compositions are useful for positioning strengthening rods in mine levels and other works by introducing into a long bore made in a wall or other surface to be strengthened the composition and a rod of substantially the same length as the bore, and rotating the rod at a rotation speed which causes it to heat up by friction with the composition to the hardening temperature of the composition so as to cause the rod to be sealed in the bore by the hardening of the composition.
