Image forming method for forming a multicolor image from a half-tone dot exposure

DETAILED DESCRIPTION OF THE INVENTION Silver halide color photographic light-sensitive materials relating to the invention are comprised of at least three layers each having a different spectral sensitivity.
The light-sensitive materials preferably applicable to the invention include, for example; those capable of forming a positive image from positive black-and-white halftone-dot images.
Next, the couplers relating to the invention each represented by Formula I will be detailed.
##STR3## wherein R.
sub.
1 represents an alkyl group or a cycloalkyl group; R.
sub.
2 represents an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R.
sub.
3 represents a group substitutable for in a benzene ring; n is an integer of 0 or 1; Y represents a monovalent ballast group; and Z represents a hydrogen atom or a group capable of being split in a coupling reaction.
In Formula I, the alkyl groups represented by R.
sub.
1 may be either straight-chained or branched and they include, for example, a methyl group, an ethyl group, an isopropyl group, a t-butyl group, a dodecyl group and so forth.
These alkyl groups further include those each having a substituent.
Such substituents include, for example, a halogen atom and each group of aryl, alkoxy, aryloxy, alkylsulfonyl, acylamino, alkoxy, hydroxy and so forth.
The cycloalkyl groups represented by R.
sub.
1 include, for example, those of cyclopropyl, cyclohexyl, adamantyl and so forth.
As for the groups represented by R.
sub.
1, the branched alkyl groups should be preferable.
As for the alkyl and cycloalkyl groups represented by R.
sub.
2, the same groups as those represented by R.
sub.
1 may be given.
As for the aryl groups include, for example, a phenyl group.
The alkyl, cycloalkyl and aryl groups represented by R.
sub.
2 further include those each having the same substituent as those given in the case of R.
sub.
1.
As for the acyl groups, each group of acetyl, propionyl, butyryl, hexanoyl, benzoyl and so forth may be given.
The groups represented by R.
sub.
2 are preferably alkyl or aryl groups and, more preferably, alkyl groups
