Abstract: A thermally processable imaging element and method are disclosed, wherein dimensional changes after thermal processing for about 5 seconds at a temperature of about 125.degree. C., do not exceed .+-.0.03%. The imaging element features an amine-generating and an amine-responsive composition. The method features preheating the element prior to exposure to dimensionally stabilize it.

Abstract: A process for producing an image which comprises the steps of:(1) applying to the surface of a substrate the surface of a photosensitive layer, the other surface of the photosensitive layer being adhered to a substantially transparent film support which is soluble or dispersible in a developer consisting essentially of a liquid capable of substantially dissolving or dispersing therein the areas of the layer other than those having a polymeric image produced by imagewise exposure in the step (2) below;(2) exposing the photosensitive layer, imagewise, to actinic radiation to form a polymeric image in the layer; and(3) washing away with the developer the film support and the areas of the layer other than those having the polymeric image to form an image of a polymeric material on the substrate.

Abstract: A method for preventing the degradation of a hydrophilic colloid solution for a silver halide photographic light-sensitive material of which the viscosity has been or is to be increased using an anionic polymer containing an acid group, which comprises incorporating into the hydrophilic colloid solution at least one compound represented by the formula (I): ##STR1## wherein R.sub. represents a hydrogen atom or an alkyl group; and R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group.
