    • An image forming process including a heating step is disclosed. The process comprises conducting said heating step in the presence of at least one compound represented by formula (I), (II), or (III). ##STR1## wherein R.sup.1 represents ##STR2## wherein R.sup.11 and R.sup.12 each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkyloxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group or a substituted or unsubstituted amino group; R.sup.11 and R.sup.12 together form a 5-membered or 6-membered ring; Q represents a hydrogen atom or a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted aryl group, or Q represents a group linked to the pyrazole ring, TIME or PUG either directly or through another atom to form a ring; TIME represents a timing group; PUG represents a photographically useful group; and n represents 0 or a positive integer.The image forming process provides for little variation in photographic characteristics even when there is a substantial variation in the heat-processing temperature.
    • 公开了一种包括加热步骤的图像形成过程。 该方法包括在至少一种由式(I),(II)或(III)表示的化合物的存在下进行所述加热步骤。 (Ⅰ)其中R1表示其中R11和R12各自表示取代或未取代的烷基,取代或未取代的环烷基,取代或未取代的烯基 取代或未取代的芳烷基,取代或未取代的芳基,取代或未取代的杂环基,取代或未取代的烷氧基,取代或未取代的芳氧基,取代或未取代的烷硫基,取代或未取代的芳硫基, 取代或未取代的氨基; R11和R12一起形成5元或6元环; Q表示氢原子或取代或未取代的烷基,取代或未取代的环烷基或取代或未取代的芳基,或Q表示与吡唑环连接的基团,TIME或PUG直接或通过另一个原子形成 戒指; TIME代表一个时间组; PUG代表一个摄影有用的组; n表示0或正整数。 即使在热处理温度存在显着变化的情况下,图像形成处理也提供了摄影特性的很小变化。
