摘要： Dye imbibition printing blanks are disclosed comprising a support bearing a layer comprising a cationic mordant, a hydrophilic colloid and a plasticizer polymer, wherein the plasticizer polymer is a latex polymer having a glass transition temperature below about 30.degree. C. comprising from about 2 to 20 wt % of units having a quaternary ammonium group. In a preferred embodiment, the latex polymer comprises a vinyl co-polymer addition product of from about 50 to 98 weight percent of acrylic or methacrylic ester units, 0 to 48 weight percent of vinyl benzene units and 2 to 20 weight percent of the quaternary ammonium group containing unit. This latex provides a dye imbibition printing blank substantially free of haze and brittleness.

摘要： A silver halide light sensitive photographic element is disclosed comprising a polyethylene terephthalate film base, at least one light sensitive silver halide-containing emulsion layer, an antihalation undercoat layer, and a process-surviving antistatic backcoat, wherein the polyethylene terephthalate film base has been formed by drafting a cast resin at a stretch ratio of at least 3.4, tentering at a stretch ratio of at least 3.4, and heat-setting at an actual heat-set temperature of at least 216° C. In accordance with preferred embodiments of the invention, the polyethylene terephthalate film base of the photographic element is formed by: (a) casting a molten polyethylene terephthalate resin in a machine direction onto a casting surface to form a continuous sheet, (b) drafting the sheet by stretching in the machine direction at a stretch ratio of from 3.4 to 4, and at a temperature ranging from 70 to 130° C., (c) tentering the sheet in the transverse direction by stretching at a stretch ratio of from 3.4 to 4, and at a temperature ranging from 70 to 130 C., (d) heat-setting the tentered sheet at an actual temperature sensed by the sheet of at least 216° C., and (e) cooling the heat-set sheet without substantial detentering to obtain a stretched, heat-set polyethylene terephthalate film.
