Fluoroalkoxy compounds of the general formula I ##STR1## wherein R1 represents a 1-3C-alkyl radical which is completely or predominantly substituted by fluorine, or a chlorodifluoromethyl radical, R1' represents hydrogen, halogen, trifluoromethyl, a 1-3C-alkyl radical, or a 1-3C-alkoxy radical which is optionally completely or predominantly substituted by fluorine, R2 represents hydrogen or a 1-3C-alkyl radical, R3 represents hydrogen or a 1-3C-alkyl or 1-3C-alkoxy radical, R4 represents hydrogen or a 1-3C-alkyl radical and n represents the number 0 or 1, and their salts are new compounds with a marked protective effect on the stomach.
A heat-developable color photographic material is disclosed. The material is comprised of a support having thereon a layer containing at least a photographic silver halide and the photographic material containing an organic silver salt oxidizing agent, a reducing agent, a [hydrophobic]-- binder and a dye releasing compound which releases a diffusible dye upon heat development. The material is characterized by a support capable of receiving a released dye or a support having thereon a layer composed of an organic high molecular weight compound which is capable of receiving a released dye. The heat-developable color photographic material can easily provide a clear and stable color image by imagewise exposure to light and a heat development procedure. A process for forming a color image using the heat-developable color photographic material is also disclosed.
A heat-developable color photographic material is disclosed. The material is comprised of a support having thereon a layer containing at least a light-sensitive silver halide, an organic silver salt oxidizing agent, a hydrophilic binder, a reducing agent for the silver halide and/or the organic silver salt oxidizing agent and a dye releasing compound which is capable of bonding to an oxidized product of the reducing agent and releasing a hydrophilic dye. The heat-developable color photographic material can easily provide a clear and stable color image by imagewise exposure to light and a heat development procedure. A method of forming a color image using the heat-developable color photographic material is also disclosed.
A heat-developable color photographic material comprising a support having thereon at least a light-sensitive silver halide, a hydrophilic binder and a dye releasing redox compound represented by the following general formula (I):
wherein G represents -OR' or -NHR2; R' represents a hydrogen atom or a hydrolyzable group; R2 represents a hydrogen atom or an alkyl group containing from 1 to 50 carbon atoms; Z represents an image forming dye group; A represents an atomic group necessary for forming an aromatic ring; Ball represents an organic immobilizing group on the aromatic ring, and when two Ball groups exist, they may be the same or different from each other; m represents an integer of 1 or 2; X represents a divalent organic group containing from 1 to 8 atoms and X with a nucleophilic group (Nu) is capable of forming a 5- to 12-membered ring together with an electrophilic center (the carbon atom marked with *) which is formed by oxidation; Nu represents a nucleophilic group; and n represents an integer of 1 or 2.
The heat-developable color photographic material can easily provide a dear and stable color image by imagewise exposure to light and a heat-development procedure. A method of forming a color image using the heatrdevelopable color photographic material is also disclosed.
