An identity determination apparatus includes a first storage unit that stores registration apparatus information used in a case where reference data obtained by imaging a portion of a surface of an object to be determined is registered, material information regarding the object which is a target for identity determination, collation apparatus information used in a case where collation data is acquired, and collation reference information used in collation in association with each other, a second storage unit that stores the registration apparatus information and the material information in association with reference data acquired in advance, a reception unit that receives collation data acquired from the object to be determined in a case where a determination process is performed, the material information, and the collation apparatus information, and a determination unit that reads out the collation reference information corresponding to the material information and the collation apparatus information which are received by the reception unit and the registration apparatus information to be specified by the collation apparatus information from the first storage unit, reads out the reference data corresponding to the registration apparatus information to be specified by the collation apparatus information, and the material information from the second storage unit, and collates the collation data received by the reception unit and the reference data read out from the second storage unit with each other using the read-out collation reference information to determine identity of the object to be determined.

Identity determination apparatus and identity determination system

A silver halide color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing a polymer coupler which is capable of forming a dye upon coupling with an oxidation product of an aromatic primary amine developing agent and which is polymerized using a polymerization initiator represented by the following general formula (I): ##STR1## wherein R.sub.1 represents a straight chain or branched chain alkyl group having from 1 to 5 carbon atoms; an R.sub.2 represents a straight chain or branched chain alkyl group having from 1 to 20 carbon atoms. The polymer coupler according to the present invention has a good stability to humidity and heat during storage of the silver halide color photographic light-sensitive material containing thereof and provides decreased formation of fog in non-image areas of color photographs obtained by means of color development processing of the silver halide color photographic light-sensitive material.

Silver halide color photographic light-sensitive material

A mordant layer for a color diffusion transfer photographic element containing a cationic polymer latex obtained by emulsion-polymerizing a monomer represented by formula (I) ##STR1## wherein R.sub.1 and R.sub.2 each represents hydrogen or an alkyl group having from 1 to 6 carbon atoms; R.sub.3, R.sub.4, and R.sub.5 each can represent an alkyl group having from 1 to 20 carbon atoms, or an aralkyl group having from 7 to 10 carbon atoms, or any two or R.sub.3, R.sub.4, and R.sub.5 together can form a ring; and X.sup..crclbar. represents an anion; as a shell component for a core component of dispersed particles of a polymer latex obtained by emulsion-polymerizing a water-insoluble monomer or monomers other than the monomer of formula (I).
