Abstract
1499596 Heat-developable material MINNESOTA MINING & Mfg CO 16 May 1975 [5 June 1974 30 April 1975] 20949/75 Heading G2C A light-sensitive heat-developable dry silver sheet material comprises (a) photo-sensitive silver halide catalyst forming means and (b) heat-sensitive reactant image-forming means including an organic silver salt oxidizing agent and a reducing agent for silver ion, further comprises a monomeric spectrally inert organic sensitizing amide added prior to halidization of the organic silver salt and having a photographic speed of at least 5 compared to an otherwise identical sheet material free of said amide and wherein the speed is taken as unity, speed being measured by sensitometric exposure to a 6100‹K light source and heat development for 30 seconds at 260 F the sensitizing amide being represented by the Formulae: wherein one of the R groups represents hydrogen or a hydrocarbon radical having no more than 12 carbon atoms and the remaining R groups represent monovalent hydrocarbon having no more than 12 carbon atoms or substituted hydrocarbon radicals having no more than 12 carbon atoms or two of such remaining R groups represent a divalent hydrocarbon radical or hydrocarbonoxy radical having no more than 12 carbon atoms, with the proviso that none of R 1 , R 2 , R 3 and R 4 in the Formula R 1 R 2 NCONR 3 R 4 may be hydrogen. The halidization forms silver halide from a minor portion of the organic silver salt. The speed is determined as the reciprocal of the exposure required to generate a density of 0À6 greater than base plus fog. A table shows the effect on the film speed of the amides and comparison compounds: N 1 N<SP>1</SP>-diacetyl-2- aminophenyl disulphide, succinimide, N 1 N- dimethyl chloracetamide, polyvinyl-pyrrolidone, N-methyl maleimide N-ethyl succinimide, butyrolactone, N 1 N-diethylurethane, p-nitrobenzamide, formamide, N 1 N-diphenyl acetamide, tetramethyl phthalamide, 1-and 5-methyl-2-pyrrolidinones, 1- vinyl-2-pyrrolidinone, benzamide, acetamide, poly-dimethyl-acrylamide, p-methoxybenzamide, p-chlorobenzamide, N 1 N-dimethylacrylamide, N 1 N-dimethyl lactamide, dimethylformamide, hexamethyl phosphonamide, N 1 N<SP>1</SP>-diacetylpiperazine, N-methylacetamide, N 1 N<SP>1</SP>-dimethyleneurea, N-methylpropionamide, 2-pyrrolidinone, dimethylbenzamide, hexamethylene formamide, caprolactam, dimethylacetamide, tetramethylurea, N-acetylmorpholine, N 1 N-dimethylnicotinamide, 1-methyl-2-piperidone, 1-methyl-2-pyridone and 1- benzyl-2-pyrrolidinone.
