Title: Photographic diffusion transfer products and processes
IPC: G03C8/28
Filed: 1969-04-22
Abstract: 1,260,528. Photographic silver salt diffusion transfer material. POLAROID CORP. April 22, 1969 [April 22, 1968], No.20557/69. Heading G2C. A photographic silver salt diffusion transfer material comprises a support carrying a light - sensitive silver halide emulsion layer, an opacityproviding material in sail emulsion layer and/or in an overlying layer present in sufficient amount to obscure an image formed in the emulsion layer, the major part of the opacity-providing material comprising a titanium dioxide pigment having a water-soluble non-ionic polyol of 4 to 10 carbon atoms at least in part absorbed thereon. A silver image receptor layer may be positioned above the said layer or layers or may be applied after exposure. On exposure and diffusion transfer processing of the material, the negative image formed in the emulsion layer is obscured by the opacity-providing material and only the positive image formed in the receptor layer is visible. The use of TiO 2  having the polyol adsorbed thereon gives whiter, less yellow image highlights. The TiO 2  pigment may also contain Al 2 O 3 , SiO 2  , hydrous oxides of Al, Ti, Zr and Si, salt of Sb, Cr and Zn and CaSO 4 , BaSO 4  and lithopone. The receptor layer contains silver-precipitating nuclei or substances and may also contain colloidal SiO 2 , a macroscopic pigment as disclosed in Co-pending Application 20555/69 and a hardening agent is disclosed in Specification No. 1, 260, 527.

Title: Improvements relating to urea-formaldehyde syrups and their use in the preparation of cold hardening compositions
IPC: C08G16/02
Filed: 1945-08-11
Abstract: Synthetic resins are prepared by reacting in an aqueous medium formaldehyde, furfuryl alcohol, urea and thiourea and heating the reaction mixture until an aqueous syrup of the resin is obtained. The quantity of thiourea is preferably between 15 and 30 per cent by weight of the urea.  The syrup is incorporated in a floor-covering composition with plasticisers, a filler or mixture of fillers which are free from alkaline constituents and an acid catalyst for the hardening of the resin syrup.  In the example, furfuryl alcohol and 40 per cent formaldehyde are refluxed and an aqueous solution of urea and thiourea added.  A filler comprising acid-resisting brick dust, silica flour, leather fibre, hardwood sawdust and chromium sesquioxide was combined with a 3 : 1 mixture of finely powdered ammonium chloride and oxalic acid, and a paste made by stirring the filler-catalyst mixture with the resin syrup plasticised with glyceryl sulphide.  Other acid catalysts may be used, for example 5 per cent of a 20 per cent solution of sulphuric acid, and other plasticisers, such as glyptal resins or mono ethers of di- or trihydric aliphatic alcohols in which the etherifying group contains not less than four carbon atoms, e.g. monophenyl glyceryl ether.
