摘要： A process for producing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizing dye and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizing dye has first and second forms, the first form having substantially greater substantial absorption in a first wavelength range than the second form. The superacid precursor is capable of being decomposed to produce superacid by radiation in a second wavelength range, but is not, in the absence of the sensitizing dye, capable of being decomposed by radiation in the first wavelength range. The secondary acid generator is capable of acid-catalyzed thermal decomposition by unbuffered superacid to form a secondary acid. While at least part of the sensitizing dye is in its first form, the medium is imagewise exposed to radiation in the first wavelength range, thereby causing, in the exposed areas of the acid-generating layer, the formation of unbuffered superacid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The components of the acid-generating and color-change layers or phases are then mixed so that the secondary acid causes a change in color of the image dye, and the sensitizing dye is converted to its second form. The acid-generating layer or phase desirably includes a cosensitizer which is a reducing agent less basic than the secondary acid generator.

摘要： An imaging medium has at least one color-forming layer comprising a thermal color-forming composition adapted to undergo a change of color upon increase in the temperature of the color-forming layer above a color-forming temperature for a color-forming time, the color-forming layer further comprising a color stabilizer which is a hindered amine light stabilizer or a nitrones. The color stabilizer prevents development of color in the medium during storage before or after imaging, thereby reducing the minimum optical density of the imaged medium and/or color distortion in the image.

摘要： An imaging medium comprises a layer, depolymerizable by exposure to actinic radiation and undergoing a reduction in cohesivity upon at least partial depolymerization, disposed adjacent a layer of an imaging material, which has a cohesive strength greater than the cohesive strength of the depolymerizable layer after depolymerization. This medium is imagewise exposed to radiation, thereby causing at least partial depolymerization of the polymer in the exposed areas, so rendering these exposed areas lower in cohesivity than the unexposed areas. The exposed areas of the imaging material are then removed from the depolymerizable layer.

摘要： A spark arrester characterized by a fixed base assembly attached over the top of a chimney, a pivot assembly attached to the fixed base assembly, and a rotatable assembly rotatably coupled to the pivot assembly. The rotatable assembly is substantially cylindrically shaped having perforate sidewall portions and a perforate top portion. A vane portion of the rotatable assembly orients a windward section of the sidewall portion towards the wind, and a deflection plate attached within the sidewall portions proximate the windward section deflects the prevailing wind up through the top portion of the assembly. Co-action between the upwardly deflected wind and the underside of the vane portion creates a low pressure area over the top portion which substantially increases the draught of the chimney, resulting in reduced risk of chimney fires and an increased burn rate for airborne embers and sparks.
