    • A method of color image formation is disclosed, comprising imagewise exposing a color photographic light-sensitive material comprising a reflective support having provided thereon at least one light-sensitive layer containing a color coupler capable of forming a color image upon coupling with an oxidation product of an aromatic primary amine developing agent and a silver halide emulsion, and processing the exposed light-sensitive material with a color developing solution containing substantially no benzyl alcohol within a development time of 2 minutes and 30 seconds, wherein said processing is carried out in the pressence of at least one compound represented by formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 each represents a hydrogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, an acyl group, or a sulfonyl group; or R.sup.1 and R.sup.2, or R.sup.3 and R.sup.4 together form a ring; X represents a substituted or unsubstituted lower alkylene group; and n represents an integer of from 1 to 4. Disadvantages due to use of benzyl alcohol can be eliminated, and reduction in color density noted when color development processing is conducted over a short time without using benzyl alcohol can be prevented.
    • 公开了一种彩色图像形成方法,包括成像曝光彩色照相感光材料,该彩色照相感光材料包括反射支撑体,其上设置有至少一个含有能够形成彩色图像的彩色成像器的感光层, 芳族伯胺显影剂和卤化银乳剂,并且在2分30秒的显影时间内用基本上不含苄醇的显色溶液处理曝光的感光材料,其中所述处理在压力下进行 的至少一种由式表示的化合物,其中R 1,R 2,R 3和R 4各自表示氢原子,羟基,取代或未取代的烷基,取代或未取代的烯基,取代或未取代的炔基 ,酰基或磺酰基; 或R 1和R 2,或R 3和R 4一起形成环; X表示取代或未取代的低级亚烷基; 并且n表示1至4的整数。可以防止由于使用苄醇而引起的缺点,并且可以防止在不使用苄醇的情况下在短时间内进行显色处理时注意到的色浓度的降低。
