Color photographic film element with blue and yellow antihalation layers

Claim 2

Colour photographic motion picture projection film element comprising a transparent film support and coated thereon in succession, a blue-sensitive silver halide emulsion layer comprising a yellow-forming coupler, a red-sensitized silver halide emulsion layer comprising a cyan-forming coupler, an intermediate layer, a green-sensitized silver halide emulsion layer comprising a magenta-forming coupler, and an antistress layer, wherein between said support and said blue-sensitive silver halide emulsion layer a yellow antihalation undercoat is provided, which comprises at least one yellow non-diffusing dye that absorbs blue light and is removable and/or decolourizable in a processing bath and between said blue-sensitive silver halide emulsion layer and said red-sensitized silver halide emulsion layer a bluish antihalation intermediate layer is provided, which comprises at least one blue non-diffusing dye that absorbs red light and is removable and/or decolourizable in a processing bath.

Claim 3

A colour photographic motion picture projection film element according to claim 1, wherein said yellow non-diffusing dye is at least one dye chosen from the group consisting of: a merostyryl dye corresponding to the general formula (I): ##STR4## in which: R 1 represents hydrogen, C 1 -C 4 alkyl, aryl, aralkyl, or a heterocyclic group, R 2 represents one of the groups represented by R 1 , carboxy, alkoxycarbonyl, aryloxycarbonyl, carbamoyl, ureido, or sulphamoyl, at least one of R 1 and R 2 being or containing carboxy or carbamoyl, R 3 represents hydrogen, C 1 -C 4 alkyl, or C 1 -C 4 alkoxy, and when R 3 is C 1 -C 4 alkyl or C 1 -C 4 alkoxy, it stands in ortho- or para-position in respect of the hydroxy group, which itself is in ortho- or para-position in respect of the methine group, and a monomethine oxonol dye corresponding to the following general formula (II): ##STR5## in which: each of R 4 and R 5 , which may be the same or different, represents: hydrogen, C 1 -C 4 alkyl, aryl, or a heterocyclic group, each of R 6 and R 7 , which may be the same or different, represents: C 1 -C 4 alkyl, carboxy, or carbamoyl, at least one of R 4 , R 5 , R 6 , and R 7 being or containing carboxy or carbamoyl, and that said blue non-diffusing dye is at least one pentamethine oxonol-type barbituric acid derivative dye corresponding to the general formula (III): ##STR6## in which: each of R 8 and R 9 , which may be the same or different, represents: hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, or aryl, and each of R 10 and R 11 , which may be the same or different, represents: one of the groups represented by R 8 and R 9 , or cycloalkyl.

Claim 4

A colour photographic motion picture projection film element according to claim 2, wherein said merostyryl dye and/or said monomethine oxonol dye as well as said pentamethine oxonol-type barbituric acid derivative dye are present in dispersed state in a hydrophilic colloid.

Claim 5

A colour photographic motion picture projection film element according to claim 3, wherein said hydrophilic colloid is gelatin.

Claim 6

A colour photographic motion picture projection film element according to claim 2, wherein a merostyryl dye corresponding to the general formula (I) is used wherein R 1 is p-carboxphenyl, R 2 is methyl, R 3 is hydrogen, and hydroxy stands in para-position.

Claim 7

A colour photographic motion picture projection film element according to claim 2, wherein an oxonol-type barbituric acid derivative corresponding to the general formula (III) is used wherein each of R 8 and R 9 represents a hydrogen atom and each of R 10 and R 11 represents methoxy.

Claim 8

A colour photographic motion picture projection film element according to claim 2, wherein a merostyryl dye corresponding to the general formula (I) is used wherein R 1 is p-carboxyphenyl, R 2 is methyl, R 3 is hydrogen, and hydroxy stands in para-position and that an oxonol-type barbituric acid derivative corresponding to the general formula (III) is used wherein each of R 8 and R 9 represents a hydrogen atom and each of R 10 and R 11 represents methoxy.

Claim 9

A colour photographic motion picture projection film element according to claim 1, wherein the side of the transparent film support that is opposite to that carrying the emulsion layers is provided with an antistatic layer comprising an electroconductive polymer.

Claim 10

A colour photographic motion picture projection film element according to claim 1, wherein the side of the transparent film support that is opposite to that carrying the emulsion layers is provided with an antistatic layer comprising polystyrene sulphonic acid sodium salt.

Claim 11

A colour photographic motion picture projection film element according to claim 2, wherein the amount of the yellow merostyryl dye and/or monomethine oxonol dye in the yellow antihalation undercoat and of the blue pentamethine oxonol-type barbituric acid derivative dye in the bluish antihalation intermediate layer varies from 250 to 25 mg per m2.
