I'm looking for the text of a patent which has the following characteristics:
- The following terms may be founded in the owner name: Heinz, Sovilla
and/or Diasec
- The patent is now public as it was probably registered in the early 80s
- It describes how to stick an image (photographic print) on the back
of an acrylic sheet (plexiglass). You then look to the image through
the acrylic and it looks perfectly transparent with vivid colours.
- It has been registered in Europe (Switzerland, Lichtenstein or other)
- It is not one of the following patents : WO1989012255, WO1993006527,
nor FR2030331
- It is sold under the name DIASEC

Hi johndifool,

Since I can't read German and the translating tools are not precise, I
cannot be certain this is the patent you are looking for. Plese take a
look and let me know what your think. If this is the correct patent, I
will post this information as an official answer.

Here's a description of the process developed by Heinz Sovilla-Brulhart:

"...This process was developed in the 70s by the Swiss chemist Heinz
Sovilla-Brulhart. Using a special adhesive, an air-tight bond is
created, fixing the photopaper to the back of UV-resistent acrylic
glass. The point of this is that when the light penetrates the layer
of acrylic glass the light refraction on the surface of the photopaper
is completely different from the effect when a photograph is framed
with a passepartout and ordinary glass. Even matt photopaper will
diffuse the light to a greater extent than a diasec-mounted
photograph. In the latter case there is less diffusion because of the
largely homogenous quality of the acrylic glass. As a result the
colours seem deeper, sharper, more brilliant and more immediate.
Furthermore, the traditional method of framing a photograph with a
passepartout and ordinary glass creates a greater distance to the
viewer's eye which is not only perceived spatially but which may also
be apprehended as an emotional, intuitive or semantic distance..."

Waiting to hear your views.
