A method of making a repositionable adhesive backed photo media is provided. The method includes the steps of (a) providing an imageable substrate or providing a photograph; (b) providing an attachment mechanism having a carrier film with opposing first and second surfaces; a thermally activating adhesive disposed on the first surface; a repositionable adhesive disposed on the second surface; and a liner disposed on the repositionable adhesive; (c) stacking the imageable substrate or stacking the photograph with the attachment mechanism; and (4) exposing the stack to heat causing the thermally activating adhesive to bond to the imageable substrate or the photograph.

An adhesive-backed photographic print is provided. The photographic print includes an adhesive composite sandwiched between a photographic print and a differential release liner. The liner has opposing first and second surfaces, the first surface having a higher release value compared to the second surface. The adhesive composite includes a repositionable adhesive, a support layer disposed on the repositionable adhesive, the support layer having a stiffness of less than about 50,000 Newton per meter in its cross-web direction, as measured according to ASTM 882-02, and a permanent pressure sensitive adhesive disposed on the support layer. The adhesive composite is disposed on the liner such that the repositionable adhesive is in contact with the first surface of the liner. The photograph print has opposing first and second surfaces, the first surface containing an image and the second surface disposed on the permanent adhesive.

A method for making a photographic print having an adhesive is provided. The method includes the steps of (a) providing a roll of dual coated adhesive tape, (b) providing a roll of photographic print having two substantially parallel edges and having opposing first and second surfaces, the first surface containing an image; and (c) laminating the tape and the photographic print. The dual adhesive coated tape includes a differential release liner having opposing first and second surfaces, the first surface having a higher release value than the second surface; a repositionable adhesive disposed on the first side of the liner; a support layer disposed on the repositionable adhesive, the support layer having a stiffness of less than about 50,000 Newton per meter in its cross-web direction, as measured according to ASTM 882-02; and a permanent pressure sensitive adhesive disposed on the support layer.

A photographic element of the conventional wet processed type or of the dry silver type which includes an antihalation or acutance dye which absorbs in the near infrared and has a relatively low visible absorption while retaining a high extinction coefficient at .sub.max. The dye is of the general formula: ##STR1## in which: m+p=2,n is 0 or 1,s is 0 or 1,Z.sup.1 and Z.sup.2 independently represent the non-metallic atoms necessary to complete a heterocyclic nucleus of the type present in cyanine dyes,R.sup.1 and R.sup.2 independently represent an alkyl or substituted alkyl, alkenyl, substituted alkenyl or aralkyl group of up to 20 carbon atoms,R.sup.3 and R.sup.4 independently represent a hydrogen atom or an alkyl, substituted alkyl, alkenyl or substituted alkenyl group of up to 10 carbon atoms,R.sup.5, R.sup.6, R.sup.7 and R.sup.8, which together may not contain more than 12 carbon atoms, independently represent a hydrogen atom, an alkyl, substituted alkyl, alkenyl, substituted alkenyl, aryl or alkaryl group, orone of R.sup.5 and R.sup.6 together with one of R.sup.7 and R.sup.8 represent the necessary atoms to complete a carbocyclic ring in which case the others of R.sup.5 to R.sup.8 are absent,Q.sup.1 and Q.sup.2 together represent the non-metallic atoms necessary to complete an acidic nucleus of the type present in oxonol or merocyanine dyes.

A radiation-sensitive element for half tone color proofing adapted to be exposed by scanning with four independently modulated sources of radiation emitting at different wavelengths within the range 550 to 900 nm, the element comprising a substrate bearing at least four separate imaging media coated thereon, said imaging media including:(1) an imaging medium capable of forming a yellow image upon imagewise exposure and processing,(2) an imaging medium capable of forming a magenta image upon imagewise exposure and processing,(3) an imaging medium capable of forming a cyan image upon imagewise exposure and processing, and(4) an imaging medium capable of forming a black or a balancing black image upon imagewise exposure and processing,each imaging medium having a maximum spectral sensitivity at a wavelength different from that of the maximum sensitivity of the other imaging media such that after exposure and processing super-imposed yellow, magenta, cyan and black or balancing black images are formed, each image being attributable to the imagewise exposure of the respective source. Three layer elements of forming yellow, magenta and cyan images may be used for preparing half-tone full color images. Exposure apparatus comprising at least three independently modulated sources, preferably semiconductor sources emitting in the region of 550 to 900 nm may be used for imaging.
摘要:
Cyanine dyes including two nitrogen containing heterocyclic nuclei, linked to each other through a rigidized conjugated 7, 9 or 11 carbon atom methine chain to form an amidinium-ion resonance system, are very good for sensitizing silver halide emulsions for use in photographic elements to be exposed to infrared radiation if one of said heterocyclic nuclei is 5-methyl-6-methoxy-benzothiazole.

Image transfer media and methods of transferring images are provided. The image transfer media comprise a sheet having a nonporous micro-embossed surface topography comprising cavities on one major surface of the sheet and an ink release coating on the embossed surface, wherein said major surface has a surface energy of about 43 dyne/centimeter or less. A method of transferring an image to a substrate comprises the steps of (a) printing a selected image onto an imaging surface of an image transfer medium of the invention; (b) contacting the imaged micro-embossed surface with the substrate using pressure; and (c) removing the micro-embossed surface of the image transfer medium from the substrate.
