摘要:
A receptor element for non-impact printing is provided comprising a support and an image receiving layer containing at least 80 % by weight with respect to the total weight of the layer of a polymer with between 0.5 and 20 mole % of moieties carrying sulphonic acid groups. Preferably the polymer is a polyester comprising between 0.5 and 20 mole % with respect to the total acid content of moieties provided by sulphoisophthalic acid and the sulpho groups are present in free acid form.

A photothermographic recording material comprising a support; a photo-addressable thermally developable element comprising a substantially light-insensitive organic silver salt, photosensitive silver halide in catalytic association with the substantially light-insensitive organic silver salt spectrally sensitized to the infrared region of the electromagnetic spectrum and a binder; and in a hydrophobic layer an antihalation dye according to the general formula (I): wherein R 1 and R 15 independently represent an alkyl group or an alkyl group substituted with at least one fluorine, chlorine, bromine or an alkoxy-, aryloxy- or ester-group; R 2 , R 3 , R 16 and R 17 independently represent an alkyl group; R 4 , R 5 , R 6 , R 7 , R 18 , R 19 , R 20 and R 21 independently represent hydrogen, chlorine, bromine, fluorine or a keto-, sulfo-, carboxy-, ester-, sulfonamide-, substituted sulfonamide-, amide-, substituted amide-, dialkylamino-, nitro-, cyano-, alkyl-, substituted alkyl-, alkenyl-, substituted alkenyl-, aryl-, substituted aryl-, alkoxy-, substituted alkoxy-, aryloxy- or substituted aryloxy-group, which groups may be substituted; or each of R 4 together with R 5 , R 5 together with R 6 , R 6 together with R 7 , R 18 together with R 19 , R 19 together with R 20 or R 20 together with R 21 may independently constitute the atoms necessary to complete a benzene ring which may be substituted; R 8 , R 9 , R 10 and R 11 independently represent hydrogen, an alkyl group or each of R 1 together with R 8 , R 8 together with R 9 , R 9 together with R 10 , R 10 together with R 11 or R 11 together with R 15 may independently constitute the atoms necessary to complete a 5-atom or 6-atom carbocylic or heterocyclic ring which may be substituted; R 12 , R 13 and R 14 independently represent hydrogen, chlorine, bromine or fluorine; and A - is a fluorinated alkyl or aryl anion in which the degree of fluorination is greater than 70%; a production process therefor and a photothermographic recording process therefor.
摘要:
A silver halide photographic material has been provided, having in a layer arrangement at one or both sides of a subbed support, corresponding with a single-side coated or a double-side coated material respectively, one or more layer(s) comprising a light-sensitive silver halide emulsion, one or more protective antistress layer(s) and, optionally, an outermost afterlayer, wherein at least one of said layers, subbing layer(s) inclusive, further comprises means in order to provide, when conditioned at a relative humidity of at most 30 %, an electrical resistance, measured as described in Research Disclosure June 1992, item 33840, of from 2 x 10 9 Ω/sq. up to 5 x 10 10 Ω/sq. for the layer having the lowest resistance.
