摘要:
An improved recording method and recording material utilizing a laser beam is disclosed. A transparent method is recorded upon with a laser beam of comparatively little energy by providing the material with a light absorbing, deformation promoting, removable layer having a high absorption coefficient.

MARKING OF PACKAGING MATERIAL UTILIZING AN EXISTING INK LAYER IN THE MATERIAL AND AN ADJACENT HEAT SHRINKABLE LAYER BY APPLYING HEAT IN THE FORM OF INDICIA TO CAUSE WITHDRAWAL OF SAID LAYERS TO ALLOW THE DIFFERENT COLORED BASE SHEET TO SHOW THROUGH. ALSO, WITHDRAWAL OF THE INK LAYER MAY BE BY PRESSURE OF A RAISED INDICIA AGAINIST A RIGID BACKING TO CAUSE SAID INK LAYER TO BE SQUEEZED AWAY, AND THE HEAT AND PRESSURE IS APPLIED TO THE BACK SIDE OF SAID BASE SHEET WITH THE RIGID BACKING BEING TEFLONCOATED TO PREVENT ADHERENCE OF SAID LAYERS.

The invention relates to compositions for forming an aesthetic image that is an work or object for display. The images are made from an image support medium of a compositions that generally includes a polymer in an amount sufficient to enable the image to have at least one aesthetic element. In different embodiments, the image support medium may be an image support stabilizer, the polymer may be a synthetic absorbent or conductive polymer, or the polymer is may be transparent or synthetic translucent polymer and a property of this transparent or translucent polymer is enhanced to facilitate the creation or preservation of the image by at least one stabilizer. The invention also relates to a method for preparing the composition and the image support medium. The method includes forming a reaction mixture comprising a monomer in an amount sufficient to provide or enable the image to have an aesthetic element, and processing the reaction mixture into a 2- or 3-dimensional shape.

Disclosed is a process for preparing a non-transparent microvoided axially stretched film including i) mixing a linear polyester having monomer components consisting essentially of an aromatic dicarboxylic acid, an aliphatic diol and optionally an aliphatic dicarboxylic acid, a non-crosslinked random SAN-polymer and one or more additional ingredients to produce a mixture, ii) forming the mixture produced in step i) in a thick film followed by quenching; iii) stretching the thick film at a temperature between the glass transition temperature of the SAN-polymer and the glass transition temperature of said linear polyester to at least twice the initial length, and (iv) further stretching the film at an angle substantially 90° to the previous stretching process to at least twice the initial length and at 90° C. or below.
