摘要:
A recording material comprising a support coated with a photosensitive layer comprising a photosensitive diazo compound enclosed in microcapsules and a coupling component. The microcapsules are produced by forming an organic solution containing the diazo compound and a wall monomer, and emulsifying the organic solution in an aqueous solution containing an anionic surface-active agent and polyvinylpyrrolidone to produce oil droplets containing the wall monomer. The wall monomer is polymerized to form a wall around the oil droplets. When heat is applied to the photosensitive layer under alkaline conditions, the coupling component reacts with the diazo compound to form a color.
摘要:
A method of processing a silver halide color photographic material using a carbamoyl or imidazole type organic metal complex bleaching agent of any of compounds of formulae (I), (II), (III), (IV), and (V) and a mercapto, mesoionic or thioether fixing agent of compounds of formulae (A), (B) and (C). A bleach-fixing composition containing the bleaching agent and fixing agent is also disclosed. The processing method provides good desilvering with little bleach fogging of the processed photographic material, and the processing composition has good stability. W in formula (III) below represents a divalent linking group. ##STR1##

The material has excellent preservability before heat recording, provides a high color density upon heat recording, and develops a black color fixable with light.
摘要:
The aqueous developer solution for a positive-working photoresist composition comprises, as dissolved in an aqueous solvent, a water-soluble organic basic compound and a specific non-ionic surface active agent which may be an alkyl-substituted phenyl or naphthyl ether of polyoxyethyleneglycol in a specified concentration. The developer solution is advantageous in respect of the completeness of removal of film residua and scums from the substrate surface after development so that the patterned photoresist layer is imparted with greatly increased accuracy and fidelity of the pattern reproduction.
