The image-receiving element includes a strip-coat layer comprising a hydrophilic colloid, such as gum arabic, and an aluminum salt which overlies the image-receiving layer and significantly reduces striations and/or haze and facilitates the separation of the image-receiving element from the remainder of the film unit subsequent to diffusion transfer photography.Type: GrantFiled: October 6, 1993Date of Patent: September 13, 1994Assignee: Polaroid CorporationInventors: James A. Foley, Nicholas S. Hadzekyriakides, James J. Reardon

Patent number: 5296331Abstract: An image receiving material comprises an image receiving layer provided on a support. The image receiving layer contains particles of a thermoplastic compound. The image receiving layer has a porous surface formed by the particles. According to the present invention, the image receiving material is prepared by forming the image receiving layer on the support and heating the image receiving layer at a temperature of higher than a softening point of the thermoplastic compound to widen pores in the porous surface. The image receiving material is preferably used in combination with a light-sensitive material which comprises a support and a light-sensitive layer in which light-sensitive microcapsules are dispersed. The light-sensitive microcapsules contain silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance.Type: GrantFiled: March 10, 1993Date of Patent: March 22, 1994Assignee: Fuji Photo Film Co., Ltd.Inventor: Keiichi Taguchi

Patent number: 5264321Abstract: Various photothermographic elements are provided containing a transparent substrate; image receiving layers; dry silver layers; interlayers; and a translucent or opacifying layer. The translucent or opacifying layer can occupy a variety of positions in the photothermographic element relative to the dry silver layers. The translucent or opacifying layers serve to help produce a reflection print upon exposure of the photothermographic element to actinic light and subsequent heating of the exposed element for image development and dye transfer.Type: GrantFiled: July 16, 1992Date of Patent: November 23, 1993Assignee: Minnesota Mining and Manufacturing CompanyInventors: Raymond J. Kenney, Takuzo Ishida, Richard C. Cotner
